We understand you're having issues detecting wireless networks with your Intel® Dual Band Wireless-AC 8265.
In some cases, switching from your OEM specific driver to our Intel® generic version may result in errors. To troubleshoot, we could try a driver only installation:
1. Download and extract our latest IT Admin driver for your adapter: WiFi_20.10.2_Driver64_Win10.zip
2. Under Programs and Features in the Control Panel, uninstall any instance of the "Intel® PROSet/Wireless Software." When prompted, choose to "discard settings."
3. Go to the Device Manager > Network Adapters > Right click on your Intel(R) Dual Band Wireless-AC 8265 and uninstall it. Make sure to mark the option to "Delete the driver software for this device."
4. Clear out your temporary files: Press the Windows* Key + R to open the run box. Type Cleanmgr.exe and press OK. Here you will need to make sure Temporary Files are checked, you may uncheck everything else (unless you're ok with the extra wait) and press OK.
5. Go to the Device Manager > Network Adapters > Right click on your Intel(R) Dual Band Wireless-AC 8265 again, this time choose to "Update driver software..." > Select the option to "Locate and install driver software manually." Here you will need to direct the wizard to the location where you extracted the IT Admin package back in step one.
Alternatively, since the issue is fairly recent, you could try a restoring your system to a date when the adapter was working properly through System Restore.
1. Select the Start button, type control panel, then choose it from the list of results.
2. Search Control Panel for Recovery.
3. Select Recovery > Open System Restore > Next.
4. Choose the a restore point created on a date where your system was working properly, then select Next > Finish.
If at this point the issue continues, and you're still unable to update the driver nor see available networks, we could suggest reinstalling your operating system (Settings > Update & Security > Reset this PC > Get started). If that's out of the question, then engaging your computer manufacturer for support would be recommendable.
Please let us know if this works.
