The new D-Link DSS-100E-18P switch is a device not manageable, this means that we will not have a management web interface where to configure VLANs, Link Aggregation, Spanning-Tree Protocol or other typical L2 functionalities, however, we do have a physical switch that will allow us to configure a total of three very interesting functionalities, which we will explain later.
This unmanageable switch has a total of 16 Fast-Ethernet ports (10 / 100Mbps) with PoE and PoE +, that is, it is compatible with the 802.3af / at standards to provide up to 30W of power per port. Thanks to the fact that it has a 230W Power Budget, we will be able to power a large number of IP cameras through its 16 PoE ports. We also have one dedicated Gigabit Ethernet port to do uplink tasks, and we even have One Gigabit Ethernet RJ-45 / SFP Combo port. Thanks to these two Gigabit Ethernet ports, we can connect this switch in a trunk way to the network, and not have a bottleneck.
This model has a 7.2Gbps switching capacity in total, the maximum forwarding speed is 5.36Mpps, uses the store-and-forward method to forward the frames, allows a MAC address capacity up to 4K addressesFurthermore, how could it be otherwise, we have auto negotiation on all ports and auto MDI / MDIX. A very important feature of this model is its physical switch that activates different options: Standard, Isolation, Long Range.
Standard: In this configuration mode, ports 1-16 can communicate with each other smoothly, the sync speed is 10 / 100Mbps.
Isolate– In this configuration mode, ports 1-16 are isolated from each other, but they can all communicate with ports 17 and 18 (the Gigabit Ethernet ports) which are the trunk ports.
Extend: In this configuration mode, ports 1-16 communicate with each other, but ports 8-16 will synchronize at a speed of 10Mbps to reach up to 250 meters away and power different devices.
Regarding the dimensions of this switch, we must bear in mind that it is a professional and rackable equipment. The dimensions are 44cm wide, 18cm deep and 4.4cm high, the weight is 2.1Kg. The consumption of this equipment depends on the number of equipment that we power by PoE, in standby it is 10W, and at maximum performance with all PoE ports working, the consumption is 265W maximum. Finally, it incorporates a fan to evacuate the hot air from the interior, something normal in a switch with so many PoE + ports, however, this fan is heard very little, ideal so that it does not make too much noise.
Although this D-Link DSS-100E-18P switch is capable of reaching a distance of up to 250 meters, if you need to go further, the manufacturer D-Link also has a PoE extender that will allow us to increase this distance to 650 meters maximum. The D-Link PoE extender is called DPE-302GE and it allows us to extend the maximum distance by 100 meters, if you need to reach more than 250 meters plus 100 meters of this extender, you can buy more extenders up to a total of four extenders, following this scheme:
As you can see, we will reach a distance of up to 650 meters maximum to feed IP cameras, logically, the maximum speed will be 10Mbps, enough for the bitrate of the cameras that is usually lower, even if they are Full HD.
Unboxing and first impressions
In RedesZone we already have with us this new non-manageable switch oriented to video surveillance, to power IP cameras at a distance of up to 250 meters at speeds of 10Mbps in its ports. This switch model is ideal for those environments where we have to cover a long distance with the network cabling to be able to power the IP cameras, since, due to the circumstances of the scenario, it is not enough only with 100-meter segments, which is the standard. . In addition, we must bear in mind that we can extend these 250 meters with the “extenders” that we have taught you before. Below, you can see in detail our video with the unboxing and first impressions:
Soon in RedesZone you will be able to see a complete analysis of this unmanageable switch for video surveillance, so you can see the real performance it provides us.
Before we start talking about why I have high latency in WiFi networks, we should know a little about how the wireless WiFi networks that we all use regularly work.
Wireless WiFi networks use the network access control protocol CSMA / CA (Carrier Sense Multiple Access with Collision Avoidance)that is, they make use of multiple access by carrier detection and collision avoidance. This protocol is essential because it allows multiple stations (such as wireless clients) to use the same transmission medium (in this case, air). Each team involved in the communication announces its intention to transmit before doing so, in order to avoid possible collisions of the frames in the air. Thanks to this behavior, we will avoid frame collisions and their subsequent retransmission. In case someone is transmitting, a random time is waited to reduce the probability of new collisions.
Basically the communication process in WiFi networks consists of three steps, first we listen to see if the network is free, if it is free we transmit the information, and finally, we wait for the confirmation of the receiver indicating that it has received everything correctly. CSMA / CA solves some typical problems in wireless networks:
“Hidden” WiFi clients: a client might believe that the channel is free, when in fact it is not because another client is transmitting and this client does not “hear” it.
Exposed WiFi clients: A client might believe that the channel is busy, when in fact it is not because the other client does not interfere with the communication.
In WiFi networks up to WiFi 5, we make use of OFDM (Orthogonal Frequency Division Multiplexing), this technology allows multiplexing a set of carrier waves of different frequencies, where each one carries information and is modulated in QAM or PSK. In WiFi 5 networks, the quadrature amplitude modulation is 256QAM, while in the latest WiFi 6 standard it supports up to 1024QAM, therefore, we can send more data per symbol in the latest standard. In WiFi 6 networks technology is incorporated OFDMA (Orthogonal Frequency Division Multiple Access), which is a huge improvement over the OFDM we had so far, OFDMA technology is the OFDM “multi-user”, allowing us to share the spectrum of a certain channel, this is called subcarriers or subcarriers, and they are ideal for low-power applications. velocity. The channel is divided and divided into groups based on the needs of wireless clients, greatly optimizing WiFi wireless networks when we have dozens of clients connected.
High latency in a WiFi network can be due to several reasons, in some cases only one reason can be given, and in other cases there could be each and every one of the reasons that we are going to indicate.
We are far from the WiFi router or AP
When we are very far from the WiFi router or AP we have a low coverage, this means that the packet will take longer to get from our WiFi client to the WiFi router or AP. The most important thing when we are very far from the access point, is that, normally there are also other WiFi clients transmitting, so we will have to “wait” until the channel is free for us to broadcast, so it could cause latency is higher than normal, and even that there are collisions and we have to retransmit the packet.
Furthermore, a very important detail is that the “slower” customers hurt the faster ones, because they take longer to send their package. When we are very far from the WiFi router or AP, the synchronization speed will drop, and we will have less real speed, therefore, this must also be taken into account.
Many WiFi clients connected at the same time
When there are many WiFi clients simultaneously connected to a WiFi router or AP, the wireless network will be more collapsed, and we will have to wait longer until the channel is free to be able to broadcast. The new routers incorporate technologies such as MU-MIMO and OFDMA that allow to improve this aspect enormously, creating groups to transmit (MU-MIMO) at the same time, and creating subcarriers (OFDMA) to serve all clients.
When we have many WiFi clients connected to the same router or AP at the same time, regardless of whether they are in “stand-by”, they will always be transferring some data, so the occupation of the channel will be greater, and we will have a greater collapse in the wireless network, therefore, we will have to “wait” until the channel is free to be able to broadcast. In this case, the same thing happens as before, if we have many WiFi clients, it is possible that some clients are “slow” either due to their type of WiFi network card or because they have little coverage, and this will affect the rest of the network.
There is a technology called «Airtime Fairness»That allows the WiFi router or AP to provide a certain time to each of the wireless clients to be able to broadcast, in this way, when we are in an environment with a mixture of fast and slow clients, we can improve the performance of the fastest clients because they will not be interrupted by slower clients, speeding up and reducing the latency of the WiFi connection. This feature is ideal in environments where there are dozens of wireless clients connected.
WiFi clients transferring a lot of data
If we have one or more WiFi clients transferring a lot of data, it will be more difficult to find a “hole” in the wireless network for us to be able to broadcast our packet, therefore, the latency will increase without being able to do anything. When we have a wireless client or several that do not stop sending and receiving data, the other wireless clients will be harmed because they will have to wait longer until they can transmit. This could be mitigated by performing a bandwidth control per connected wireless client, so that the same WiFi client is not able to occupy all the available channel time, in this way, the latency of the WiFi connection will decrease.
Interference with other WiFi networks and frequency bands
If our WiFi router or AP is transmitting on the same WiFi channel as other neighboring networks, we could have interference with both your router or AP, as well as your WiFi clients because they will be “occupying” time in the air. These interferences could also cause high latency because our customer will have to wait until the network is free.
The 2.4GHz band has a greater range than the 5GHz band, this is a clear problem for interference with neighbors’ WiFi networks. If we use the 2.4GHz band, it is very likely that we will have more interference with neighboring WiFi networks, and, therefore, we will have higher latency in the connection. If we use the 5GHz band (which has less range), surely we will not have interference with neighboring networks, or at least, we will not have so much interference with neighboring WiFi networks, therefore, if you want to have the best latency you should always use the band of 5GHz. Soon we will have available the 6GHz band thanks to the WiFi 6E, this will allow us to reduce the interference of the WiFi networks enormously by having a new frequency band.
As you have seen, these are the reasons why we could have a high latency in our WiFi connection, now we are going to give you some solutions to mitigate the problem (because surely you cannot solve it completely).
Solutions to mitigate the problem of having high latency in WiFi
If you are far from the router
If you are far from the WiFi router or WiFi access point, the best thing you can do is get closer to the AP that is broadcasting, in this way, you will have better coverage, higher synchronization speed, higher performance and lower latency. In the case that you are a WiFi network administrator, we recommend that you activate the Airtime Fairness functionality, to prevent these “slow” clients that are so far from the AP, harming the faster clients that are close to the access point . Also, it might be a good decision to use the disconnect functions for WiFi clients that are too far away, in order to kick them out of the WiFi network and not harm others.
If there are many WiFi clients connected at the same time
In the case that there are many WiFi clients connected at the same time to the same WiFi router or AP, we have two ways to make this more bearable and not affect latency. The first thing we can do is activate the “Airtime Fairness”, so that slow clients do not harm faster clients. Another option is to install an additional access point to distribute the load of the wireless clients, or a WiFi Mesh system with simultaneous triple band to have a frequency band specifically for the interconnection of the nodes (if it allows Ethernet backhaul much better), In this way, we will be distributing all the wireless clients among several nodes, performing a load balancing.
If you have clients transferring a lot of data
In the event that you have clients transferring a lot of data, the most advisable thing is to limit the maximum bandwidth per wireless client, for example, put each WiFi client connected to our network to download at 50Mbps symmetric speed, in this way, we will avoid that a wireless WiFi client monopolizes all the WiFi bandwidth of the network. In addition, in this case it would also be advisable to enable Airtime Fairness to prevent slow clients from harming faster ones, and to optimize the wireless network as best as possible.
Use 5GHz or 6GHz and change channels if necessary
In the event that you are using the 2.4GHz band to connect, we recommend connecting to the 5GHz band or to the future 6GHz frequency band, in order to have as little interference as possible. In the event that you have interference, changing the WiFi channel will also improve the latency of the connection, in addition, if you use very large channel widths such as 40MHz in 2.4GHz or 80MHz in 5GHz, possibly if you reduce the width of channel (at the cost of reducing the maximum real speed) you will have less interference with other WiFi networks.
As you have seen, depending on the scenario where we will find ourselves, we can perform different actions in order to improve the latency of our WiFi connection.
The Asuswrt-Merlin firmware has VPN servers such as OpenVPN and IPsec, as well as different advanced VPN clients, including an OpenVPN client. One of the most important characteristics of this firmware is that we can forward all the traffic of a certain client on the LAN through an OpenVPN tunnel that we build. Now, the Asuswrt-Merlin developer has done a full review on OpenVPN routing, serving as the basis for the new VPN Director functionality, which is coming soon, and which is currently in beta for testing.
Starting with the new version 386.3, all OpenVPN routing will be done directly by the firmware, instead of the OpenVPN client that we configure and the firmware modifies later. Now the internal routing will be cleaner, it will no longer be necessary to remove unwanted routes that were incorporated by the OpenVPN server. Thanks to this revision, now the possibility of “redirecting Internet traffic” will behave much better, because the remote server will not override it silently, in addition, we can allow or not certain routes to be installed from the OpenVPN server (when we we act as a customer). Now there will no longer be a policy and a strict policy as previously in the Asuswrt-Merlin firmware, now we will simply have a single policy.
Another feature that has changed is the operation of the so-called Kill-Switch, a function that allows you to block traffic if it does not go to a remote OpenVPN server, with the aim of protecting us from possible tunnel drops and filtering information. Now the Kill-switch will not activate if we manually stop the VPN tunnel, either through the graphical user interface or via SSH by commands. Now the Kill-switch works in these cases:
If the VPN client is configured to connect to the router startup, and the kill-switch is enabled, then all traffic will be blocked until the OpenVPN client connects.
If the VPN client terminates the connection abruptly, then this Kill-switch will work too.
In addition, this Kill-switch would also work in the case of configuring a policy of “redirect all traffic through a VPN client”.
What is VPN Director?
VPN Director replaces the strict policy and policy-based routing policies that we had up to now. Now all the rules will be configured in a centralized location that will be in charge of managing all the VPN client connections (only with the OpenVPN protocol), ideal for making it easier for users to configure them. The new menu will be in the “Advanced / VPN Settings” section, as you can see below:
This new functionality will allow us to configure in detail all the policies we want, up to 199 rules in total, and assign which VPN tunnel we want a specific client on the LAN to access. In this way, we can easily configure certain clients to go to the Internet through different VPN services, or to go directly if we select the Internet WAN interface. In this menu we can also start the different VPN clients, see if we have the kill-switch enabled and much more.
A very important detail is that the “policy” to be followed by this VPN Director will be:
OpenVPN clients to redirect all traffic will have the highest priority.
WAN rules will also have high priority, but below total traffic redirection.
The OpenVPN 1 client rules will take precedence over the OpenVPN 5 client rules.
The rules can be easily enabled and disabled by clicking on the “Enable” section in the rules.
Another important aspect is that we can “mark” specific IP addresses, or using CIDR notation to put subnets.
As you have seen, for users who use the OpenVPN client with VPN services such as Surfshark, PureVPN, NordVPN and many other services, this new functionality is ideal because we can see all the rules directly in a single menu. All these rules will be stored directly in JFFS (internal FLASH memory), and not in NVRAM, with the aim of saving space and being able to store up to 199 rules in total. We recommend you access the VPN Director beta thread where you will find all the details.
Having a good Internet connection through Wi-Fi is very important today. We have more and more devices that are compatible with wireless networks and this means that we must avoid problems that may affect coverage and stability. However, this is not always possible and we find errors to navigate. We see that the speed is very slow, that it connects and disconnects, that the signal does not reach certain places … We are going to show some deals on Amazon on devices for improve Wi-Fi. We will also see some routers and network switches at a reduced price.

In RedesZone we do not have any agreement with brands. We search for the best deals on networking devices on Amazon and take a small commission in return.
As we have mentioned, when surfing the net, when registering on sites, making purchases or using different services, we can leave a lot personal information. Here we can include our name and surname, email address, telephone number and even the purchase details of the bank card.
By registering on an online platform we are trusting that that site is legitimate and will not use that information for bad purposes. For example, when we enter a web page to make a purchase, the normal thing is that we put at least our e-mail, home address, name and surname, as well as the telephone number.
In case that site is attacked or there is some kind of filtration, all that data could end up in the wrong hands or end up being public on the network. We have seen numerous such cases. But one of the most common problems is that we forget a social network or a forum in which we registered years ago. That service may have been forgotten, that it is no longer used by users, but our data is still there.
Keep in mind that our personal information has great value on the net. It can be used for different techniques that hackers use, as we will see. Hence, it is very important to avoid leaving a trace and control the information that we make public.
What can they do with our personal data
If a hacker manages to get hold of our personal data on the Internet, they could have a wide range of possibilities to use it and profit from it. An example is the fact of being able to include ourselves in spam campaigns. At the end of the day they could know our email address, name and even phone number. They can also have information about our tastes, since they will obtain data from pages we have visited, stores where we have bought, etc.
Another very important question is that all this could be used to launch custom phishing attacks. This is important, as the probability of success is greatly increased. That is, it is not the same as a hypothetical victim receiving a generic email to log into a site and that it is actually a trap, to a more personalized email, with our name and even with a platform that we use as bait. They could be significantly more likely to succeed.
They could even reach impersonate our identity. This is dangerous since they could create profiles on social networks with our data, add friends or relatives who would not suspect anything and, in this way, attack them as well. For example, they could do this if they send messages through social networks that contain malware or malicious links. That is why it is always important to detect bots on social networks.
Therefore, as we have seen, it is very important to prevent our personal data from remaining on the network on platforms that we stop using. You always have to protect the information and not take risks of any kind. Otherwise we could be victims of multiple cyber attacks.
DeadHash is a program Open Source that we can use on both Linux and Windows systems, as well as Android. It is completely free and allows us to check if the hash of a file that we have downloaded from the Internet is legitimate.
Keep in mind that many developers provide this information precisely so that users can verify that they are looking at the correct file. One way to ensure install legitimate software and that it has not been maliciously modified.
Using DeadHash is very simple. The first thing we have to do is download it. There we will meet the different versions. For Windows we can also see the portable version alternative, so as not to have to install it.
How DeadHash works
The mode of use of DeadHash It is very simple. Once we install it or run it through its portable file, we will find a first screen like the one we see in the image below.
On the left we will see the section of File. There we have to click to select the file that we want to analyze. You just have to go to the route where we have it saved and that’s it. We can also simply drag the file that interests us there. Later we will give Calculate, to show us the information.
Keep in mind that the time it takes for DeadHash to process it will depend on the File size. However, it is usually not more than a few seconds. Once it is finished we will see the list of hash values of the file.
We can easily copy the values or give it to export in a CSV file and be able to use it in the future. DeadHash supports hash algorithms such as MD4, MD5, SHA1, SHA-224, SHA-256, SHA-384, SHA-512, RIPEMD160, and CRC32. It is an option to generate hashes of files.
If we enter the menu we can change the language, as well as other parameters of the program. We can also select or remove different algorithms to show them or not. This is useful if we only want something specific. We will not find many more options, since it is a simple application that has the essentials.
In short, DeadHash is a simple program to analyze hashes of files that we have downloaded. A way to maintain security at all times and not have problems when installing a program that we have downloaded and that we do not know if it has really been modified in a malicious way and be a problem for our security.
The hackers they are constantly looking for a way to steal information and attack what is most used. Without a doubt, VPN services are today, so they have a possibility there to carry out different strategies and attack users.
According to data provided by NuspireSpecifically, attacks against Fortinet SSL-VPNs increased by 1,916% and against Pulse Connect VPNs by 1,527% during the first quarter. In the first case, they took advantage of the CVE-2018-13379 vulnerability and in the second, CVE-2019-11510. These flaws could allow malicious file download and disclosure.
In both cases they launched security patches, as usual. It is very important to always have the latest versions and updates that may be available. In this way we can correct possible bugs that may appear and preserve privacy when using VPN or any program.
However, not only have attacks increased through these two vulnerabilities that we mentioned. The truth is that they have done it against different VPN programs, the amount of fake software that tries to look like legitimate programs and scams targeting both private users and companies that use this tool has increased.
It is a fact that in recent times the use of VPNs has grown due to the rise of teleworking as well. We need to connect to computer equipment that we do not have physical access to. This also opens the door for hackers to carry out attacks.
Decrease in malware and other attacks
It should be noted that, unlike what has happened with attacks against VPN, in general malware has decreased in the first quarter of the year. According to the Nuspire report, malware has decreased by more than 54%. Keep in mind that there are many varieties of viruses.
There has also been fewer botnet attacks and similar threats. Much of this significant decline has been due to the dismantling of Emotet. This has been a fact of great importance in cybersecurity so far in 2021.
However, security researchers indicate that it is not ruled out that hackers devise new formulas to distribute malware, through new threats that they can distribute on the network.
This means that we must be protected at all times. We must avoid the entry of malicious software, for which we will need to have security programs, such as an antivirus or firewall. It is also very important to update the equipment and in this way prevent them from exploiting vulnerabilities.

As we have indicated, the elements that will allow us to connect to the network are different. Some we can modify and adapt to our needs. We can make the connection speed faster, that everything goes more fluid and have less problems connecting our equipment.
Sometimes it is convenient to carry out some changes in the router or in our devices. It may even be necessary to make it work better. In this case, when we talk about time of DHCP lease or Lease time, we refer to the refresh time of the IP. Basically it is the time that elapses until the IP address changes.
We can easily configure this value in the router. This could be interesting on certain occasions. Usually it comes configured in 12 or 24 hours. We can lower or increase that time.
Keep in mind that our telephone operator assigns us a dynamic IP address when we connect. We are going to keep that IP for a while, unless we turn off the device. Now, we can also determine the time on the device itself.
This term can also be found as DHCP rental. But, why can it be interesting to change the concession time? This might be necessary for example in a network with many connected computers. We could have problems if the IP does not restart after a certain period of time has passed.
This means that we must configure it to renew earlier. If, for example, we have it set by default so that it changes every day, we can set it to do so after a few hours. We could also need the opposite, that this time be lengthened. We will be able to easily modify it according to our interests.
How to view DHCP lease time
On Windows 10, which is the most used operating system on desktop computers, we can easily see the DHCP lease time. To do this you simply have to run a command. We will not have to install anything additional to obtain this information.
The first thing we are going to do is go to Start, open the Command Prompt and execute the command ipconfig / all.
It will show us a series of data, as we can see in the image. We will have information regarding the type of network card, the physical address, whether or not we have DHCP enabled, etc. But what interests us in our case is the information that shows the concession obtained and when it expires. We will easily see it with the exact time.
We can also use it in Windows PowerShell. The procedure is exactly the same. You just have to go to Start, open PowerShell and execute the command ipconfig / all. There it will show us this information that we have seen. It will also show us data related to the network and, what interests us most, the IP lease time.
In both cases we will see the exact moment in which we obtained the grant of that IP address and also when the grant will expire. That time interval is what we can modify in the router, in case we are interested in doing so. It is a simple process and we will only need a series of data to be able to access and change it.
How to modify the IP lease time on the router
Inside the router we can configure different parameters that can help improve security or even performance. One of these options is to modify the Lease time or lease time of an IP address. It is something that we can do with practically any home router.
To achieve this we will have to access the device. We need to know the default gateway. Generally it is 192.168.1.1, but it could be something else. To confirm we can go to the Command Prompt again and execute ipconfig. There it will show us the exact address.
Once we know the default gateway we can access the router. The password is usually generic, of the type 1234, admin1234, etc. Of course, we always recommend changing it and using a different one, created by us, and that is totally safe. We must never leave the factory settings, as it could allow intruders to enter our network and affect the speed and quality of the signal. You always have to create keys that are random and that meet the appropriate requirements to avoid taking risks.
When we are in the router, to change the lease of an IP address can depend on the model. However, the steps will always be similar. We will have to go to the menu, we enter settings or advanced configuration and there to LAN. The option to change the Lease time may appear there or we may have to enter DHCP Server.
As we see in the image, it shows us first that the DHCP server. This is basic for what interests us. It also shows us the range of IP addresses where it is going to act and, below, the concession time measured in hours. This is what we can modify. We can put what interests us.
If we enter device information and DHCP, all the devices that are connected to the network will appear and when the IP address assigned to them will expire. This also provides us with information that may be relevant.
In short, by following these steps that we have explained, we can change the IP address lease time. It is a simple process, as we have seen. It can be useful at different times if we are interested in having the IP renewed more frequently, especially if we have many devices connected to a network and we have problems.
In order to surf the Internet it is necessary to have a series of devices and tools. We can have different types of programs, configuration and equipment that help us in our day to day. All this will make it possible for us to navigate normally. But of course, on many occasions some of these factors may not work properly and that is where we would be unable to connect.
The virtual hosted network adapter is a Microsoft service that helps us to turn on or off the wireless network or virtual Wi-Fi. It may happen that it does not appear, that it is not available, and the causes are diverse, as it usually happens in these cases.
Usually this appears due to having made an update in the system. There may have been an error and this causes services like this not to appear. It is something relatively common and that can affect the operation of the systems or devices that we use in our day to day life.
It could also happen some system level error. Windows could be affected by different problems that could interfere with the operation of these types of services. This causes us to encounter the message that the hosted network could not be indicated.
Hosted Network Virtual Adapter Does Not Appear
As it usually happens when errors of this type appear, we will always have different options to solve it. We are going to see some simple steps that we can take into account and thus avoid the error that indicates that the virtual hosted network adapter is not available appears.
Update network drivers
This is something basic but it can solve many problems of this type. We must always have the latest versions, especially when it comes to devices connected to the network. In this way we will be able to include all the improvements that are present, in addition to solving certain problems.
Therefore, the first thing we are going to do if we see that the hosted network adapter does not appear or gives an error, is to update the network drivers. To do this we must go to Start, enter Device Manager, go to Network adapters and there we click on the corresponding network card, click with the second mouse button and click Update driver.
Check that Windows is correctly updated
We have mentioned that one of the main causes for this problem is an error when update windows. The update may have been hanging or that there is even a bug with that version and it is generating conflict.
Therefore, we must confirm that Windows has been updated well. We can go to Start, we enter Settings and we go to Update and security. There we will see the exact version that we have and we will check if there is something pending to be installed. It is important that a system update is completed correctly, otherwise something could remain and cause problems of this type.
Reset the wireless hosted network
Another step we can take to solve this error is reset wireless hosted network. Basically what we are going to do is deactivate the hosted network manually and then re-enable it. This way we will get it to be restored and see if the problem is solved.
To achieve this, we have to execute the following commands:
netsh wlan start hostednetwork
netsh wlan set hostednetwork [mode=]allow
Later we will have to restart the computer. In this way it will be restored correctly and we can see if this problem has really been solved or not.
Restart the WLAN Auto Configuration Service
The automatic WLAN configuration service or AutoConfigWlan Allows you to establish a connection between the computer and the wireless network or an adapter. It is linked to the Windows Hosted Network Virtual Adapter, so it could be the cause of this problem.
To do this we have to go to Start, look for Services and there, once a new window opens, we look for Automatic WLAN configuration. We have to click with the right button of the mouse and we give it to Stop and later to start it again.
Once this is done, once again we will have to restart the computer for the changes to take effect correctly.
Reset Windows Network
We can also take into account the possibility of resetting the network in Windows. On many occasions this option can solve problems that appear. What we are going to do is revert to the default values of the network adapters.
To do this, we have to go to Start, we enter Settings, we go to Network and Internet and there we will see the option to Network reset. We have to give it to follow and accept. We will restart the system again.
Check that there is no malware on the computer
Of course we must also make sure that there is no security threat on the computer. On many occasions there may be malware that jeopardizes the proper functioning and that affects the devices and the different functions.
It is essential that we keep systems safe, with a good antivirus and firewall installed. In this way we can detect possible security threats and know if a virus or any malicious software could be causing this network error. We have both free and paid options available, although we must always choose one that really protects us.
Ultimately, following these steps we can solve the problem when the message that the virtual network adapter does not appear appears. You just have to take these tips into account and see if it is solved. It is an error that can appear occasionally and should be fixed.
