How to fix Wifi not found error after updating Windows 10
Why is there no Wifi after updating Windows 10?
- Wifi driver or wireless adapter driver is not updated and not compatible with Windows 10 update. In some cases, Wifi driver is lost after updating Windows 10.
- If reinstalling the Wifi driver does not fix the problem, the problem here may be caused by the VPN software not being supported during the Windows 10 upgrade. If you have an old VPN client, specifically the Cisco VPN client or client Sonic Global, then it is certain that this software is the cause of Internet connection problems in Windows 10.
Method 1. Use Command Prompt to fix no Wifi problem after updating Windows 10
Note: Before editing, back up the registry to restore in case something goes wrong.
1. Type cmd in taskbar search box and right click on Command Prompt > Run as administrator to run as admin.
2. Type the following command and press Enter key:
reg delete HKCR\CLSID\{988248f3-a1ad-49bf-9170-676cbbc36ba3} /va /f
3. Type the command below into the Command Prompt dialog box and press Enter:
netcfg -v -u dni_dne
4. Restart the computer and check the Wifi settings. There will now be a list of all available networks in range.
Note: If you have a Cisco VPN client, Sonic Global client, or other VPN software running on your computer and intend to upgrade to Windows 10, uninstall the VPN before continuing.
Method 2. Update Wifi Driver on Windows 10
1. Run Driver Talent and click the Scan button to scan the computer, it can check all driver problems in general and network drivers in particular.
2. Click the Update or Repair button to fix the Wifi driver problem.
3. Restart the computer.
Note: Users can also try the network version Driver Talent for Network Card. This version can help fix driver problems without Internet connection.
Method 3: Optimize Wireless Adapter Settings for Best Wifi Performance
1. Use the keyboard shortcut Windows + X or right-click on the Start menu, select Power Options.
2. Scroll down and click Additional power settings (This option is available to Windows 10 Fall Creators Update/Creators Update users. For previous versions, go directly to Step 3).
3. Click Change plan settings.

If the above solutions don’t help, try turning Wifi back on in Settings or uncheck the option Allow the computer to turn off this device to save power in Device Manager > Network Adapters > Properties > Power Management.
Method 5: Reset TCP/IP stack
1. Right-click the Start Menu button and select Command Prompt (Admin).

Method 6: Reinstall the adapter
If reinstalling the driver doesn’t work, try uninstalling the adapter first. Here’s how to uninstall the Network adapter in Windows 10:
- Go to Search, type devm and open Device Manager.
- Find your Network adapter.
- Right click on your Network adapter and select Uninstall.
- Follow the instructions on the screen.
- Restart your computer.
- Now, go ahead and install the driver for the Network adapter again, as outlined above.
Method 7: Reset your adapter
As the name suggests, find the small button on the back of the adapter, press and hold it. Wait a few minutes for the signal to return and try connecting to the Internet again.
Method 8: Update the router’s firmware
This is very complicated. It’s best to check your router’s manual for more instructions on how to update it.
Method 9: Switch to maximum performance mode
- Go to Search, type power management and open Power & Sleep.
- In Related Settings, go to Additional Power Settings.
- When the Power Options window opens, find your current mode and click Change plan settings.
- Go to Change advanced power settings.
- Find Wireless Adapter Settings and set Power Saving mode to Maximum Performance
- Click Apply and OK to save the changes.
Just remember that Maximum Performance mode puts extra pressure on your device, so the laptop battery can drain faster.
Method 10: Make sure nothing interrupts the Wifi signal
Certain devices and hardware unrelated to your computer can disrupt the Wifi signal. For example, microwave oven weakens Wifi signal. So make sure there aren’t any devices that can interrupt the signal near your router.
