WiFi does not work after upgrading to Windows 10

No WiFi after upgrading to Windows 10? WiFi getting disconnected? If your Wi-Fi does not working after you upgrading to Windows 10, then this post will show you how to try and fix the problem.

No WiFi after upgrading to Windows 10

After you upgrade from Windows 8.1 to Windows 10 Pro or Windows 10 Enterprise, you may find that no wireless networks are available. Wired Ethernet connections may also not function properly, if you are using built-in Ethernet adapter or a USB Ethernet adapter. This could occurs due to presence of unsupported VPN software.

Here are a few things you could try:

1] Restart your computer. Reset your Wi-Fis router and see if that works.

2] Next check if you have any VPN software installed on your computer. If it doesn’t not support Windows 10, then uninstall it and see if it resolves the issue. If it does, then go visit the software vendors website and download the version which supports Windows 10.

3] Disable your Firewall and see if that is the cause.

4] Open  Settings > Network & Internet > Airplane mode. Ensure that Airplane mode is Off.

5] To resolve this issue, KB3084164 recommends the following. First, run in a CMD, netcfg –s n to see if DNI_DNE is present in the resulting list of networking protocols, drivers and services. If so, proceed.

Run the following commands, one after the other, in an elevated command prompt:

reg delete HKCR\CLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f
netcfg -v -u dni_dne

If this does not work for you, create a system restore point and then Run regedit to open the Registry Editor. Navigate to the following registry key:

HKEY_CLASSES_ROOT\CLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3}

If it exists, delete it. It basically does the same thing as the ‘reg delete‘ command.

6] The Network Reset feature in Windows 10 will help you reinstall Network adapters and reset Networking Components to original settings.

7] If you do not see the Wi-Fi network’s name at home, first ensure that your router is set to broadcast the network’s name.

To check this, you will have to connect your PC to your router using an Ethernet cable. Next open your browser and type the IP address for your wireless router in the address bar and hit Enter. Sign in and visit the Wireless Settings page. Now ensure that the settings Enable SSID Broadcast, Wireless SSID broadcast, etc, is set to On.

The issue could affect Surface devices too.
