If you have no WiFi after upgrading to Windows 11/10, installing Windows Update or installing a Feature Update, or getting disconnected randomly, this post will show you how to try and fix the problem.
Fix No WiFi after Windows Update
After installing Windows Updates or a Feature Upgrade, you may find no wireless networks are available. Wired Ethernet connections may also not function properly if you use 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 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 the Network Reset feature.
WiFi does not work after installing Windows Update
1] Check the Router setting
If you do not see the Wi-Fi network’s name at home, ensure 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 11/10, uninstall it and see if it resolves the issue. If it does, visit the software vendor’s website and download the version supporting Windows 11/10.
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 does the same thing as the ‘reg delete‘ command.
6] Update the WiFi driver
You may want to update your WiFi driver and check. You may run Windows Update or use Devices Manager.
Alternatively, you may uninstall your WiFi driver and then download and install the WiFi driver using the manufacturer’s website.
7] Use the Network Reset feature
The Network Reset feature in Windows will help you reinstall Network adapters and reset Networking Components to their original settings.
You must connect your PC to your router using an Ethernet cable to check this. Next, open your browser, type your wireless router’s IP address in the address bar, and hit Enter. Sign in and visit the Wireless Settings page. Ensure that the settings Enable SSID Broadcast, Wireless SSID broadcast, etc., are set to On.
The issue could affect Surface devices too.

How do I know if my WIFI adapter is faulty?
The easiest way to determine if the hardware is faulty is to connect it to another working PC or Laptop. If everything is working as expected, and you can connect with a wifi connection, then the problem is on your Laptop. If not, you must check with the OEM and get a replacement if it’s still under warranty.
Can a WiFi adapter stop working?
Yes, the adapter may stop working. The hardware is constantly running and can temporarily suspend its operation unless restarted. If it happens occasionally, it is still ok; however, if the frequency increases, the hardware faces an internal issue. You can connect with the service center and get it checked. At times, there are minor issues that can be rectified with a small budget.
