G5 5505 Post Windows 11 upgrade Wifi not working, but bluetooth shows up...
I have a G5 5505 with the Qualcom bluetooth + wifi module. Oddly after the Windows 11 upgrade my wifi has stopped working and will not show up in the "Device Manager" but the bluetooth shows up and works.
I had unidentified devices post upgrade that I tried to install drivers for to no effect. I removed the unidentified devices and they've not returned. I've uninstalled the bluetooth module and removed the qualcomm driver, then rebooted. The bluetooth adapter shows up again but the wifi still will not appear.
At this point I'm stumped. I unfortunately removed the windows 10 files as I couldn't afford the 25 gb they were taking.
Is this an issue of an outdated driver, or do I need a clean install of windows 11? Has anyone seen this?
The qualcomm driver downloads as "Qualcomm-QCA61x4A-QCA9377-Wi-Fi-and-Bluetooth-Driver_V5JJK_WIN_12.0.0.1118_A45_04.exe". In windows device manager the bluetooth hardware shows as "Qualcomm QCA61x4A Bluetooth". The device manager is flickering every 15-30 seconds as though it's trying to update and failing.

Ok. So downloading the latest driver from AMD (adrenalin 2020-22.1.1) that came out yesterday and performing a factory reset on the install and not keeping the user preferences fixed the issue for me. Upon finalizing the install and performing the last reboot the wifi came up. Perhaps it was a driver incompatibility, perhaps it was the user preferences, or perhaps the factory reset did the trick. However I am up and running properly now. Perhaps another bug will crop up, but for now this is up and running. I hope this helps anyone else who hits this issue.

Just a shot in the dark but have you installed the chipset drivers?

Tricky to do with this laptop as it's all one driver set. As it's the AMD Ryzen and Radeon they integrated both sets of drivers into one. However Dell lists them as separate on their site, the chipset driver installs the graphics driver as well, and visa versa.
AMD just put out a new driver package. I'll have it do a clean install after I remove the bluetooth module from device manager to see if the wifi is picked up. If that doesn't work I'll try a "sfc /scannow". I'd really rather refrain from doing a full wipe and restore of windows 11. I'll also give a linux boot usb a shot to validate that Dell's 1.9 Bios for this machine that installed automatically right after the update to windows 11 didn't kill the wifi.
