Methods to follow to fix the WiFi adapter on Windows 10

Solution 1: Make use of network troubleshooter

One of the best and easiest ways to fix the WiFi adapter on Windows 10 is to run the network troubleshooter. All you need to do is run and it will do the required work for you. Here's the steps to run the network troubleshooter in Windows 10:

1. Firstly, navigate to Settings.
2. Now, go to Updates & Security and then Troubleshoot option. 
3. Choose Internet Connections, and then Run the Troubleshooter.
4. Keep following the on-screen instructions and let the process finish.

In case the network troubleshooter fails to resolve the problem, then jump to the next solution.

Solution 2: Perform registry tweak via command prompt

Users who are facing the problem with a WiFi adapter in Windows 10 can fix the problem using this method. So, you can perform the following steps as below:

1. Firstly, right click on the Start Menu button and select Command Prompt (as admin)
2. Now, enter the given command and press Enter:
netcfg –s n
The command displays a list of network protocols, drivers and services. Therefore, check if DNI_DNE is in the list or not. If it is present, then it's a problem.
3. In case DNI_DNE is listed, then using the command prompt window, enter the following command and press Enter: reg delete HKCRCLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3} /fnetcfg -v -u dni_dne

This command should resolve the issue. However, if you get an error 0x80004002 after entering the command than this value is either not in the registry, or need to be deleted permanently. So here’s what you need to perform if you receive this error code:

1. Navigate to Search, type regedit and launch Registry Editor.
2. Now, go to the following path:
HKEY_CLASSES_ROOT\CLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3}
3. Lastly, delete DNI_DNE if it still exists in the registry.

Solution 3: Reset TCP/IP stack

If the above two solutions didn’t work to fix the WiFi adapter on Windows 10, then simply try resetting the TCP/IP stack. For doing that, enter a few command lines into the command prompt. This is how you need to do:

2. Now, enter the following lines into Command Prompt, and then press Enter after each one:
netsh int ip reset
netsh int tcp set heuristics disabled
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global rss=enabled
3. Finally, restart your computer and check if you’re able to connect to WiFi now.

Solution 4: Upgrade network drivers

Since you cannot download anything with your current internet connection, so download the necessary drivers via another computer or through another network.

In order to get the most suitable drivers for your system, go to your network adapter manufacturer’s website. On the website, search for the drivers for your network adapter. Hopefully, a fresh set of network drivers will surely fix the WiFi adapter on Windows 10 system.
