If you have no WiFi after upgrading to Windows 10, installing Windows Update or installing a Feature Update, or if WiFi gets disconnected randomly, then this post will show you how to try and fix the problem.
No WiFi after Windows 10 Update
After you install Windows Updates or a Feature Upgrade, you may find that no wireless networks are available. Wired Ethernet connections may also not function properly if you are using a built-in Ethernet adapter or a USB Ethernet adapter. This could occur due to the presence of unsupported VPN software.
If there is No WiFi after Windows 10 Update, here are a few things you could try:
- Check Router setting
- Reset your Wi-Fi router
- Disable VPN software
- Disable Firewall software
- Ensure that Airplane mode is Off
- Check networking protocols
- Update WiFi driver
- Use Network Reset feature.
1] Check Router setting
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.
2] Reset your Wi-Fi router
Restart your computer. Reset your Wi-Fi router and see if that works.
3] Disable VPN software
Next check if you have any VPN software installed on your computer. If it does not support Windows 10, then uninstall it and see if it resolves the issue. If it does, then visit the software vendors website and download the version which supports Windows 10.
4] Disable the Firewall software
Disable your Firewall and see if that is the cause.
5] Ensure that Airplane mode is Off
Open Settings > Network & Internet > Airplane mode. Ensure that Airplane mode is Off.

6] Check networking protocols
To resolve this issue, KB3084164 recommends the following. First, in a CMD, Run 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] Update WiFi driver
You may want to update your WiFi driver and check. You may run Windows Update or use the Devices Manager.
Alternatively, you may uninstall your WiFi driver and then download and install the WiFi driver using the manufacturer's website.
7] Use Network Reset feature
The Network Reset feature in Windows 10 will help you reinstall Network adapters and reset Networking Components to original settings.
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.
