OS: Windows 11
Machine: Inspiron 14 5000 2 in 1
Driver: Intel Wireless AC -9560
When did it happen: Last night, 6/25/2022, after a windows update. Showed error code 10 on driver
More important info: Ethernet & wireless driver did not appear under network adapters. However, when I connected my laptop to my docking station, the ethernet adapter appeared. The wireless adapter did not apear but showed as disabled under devmgt.msc.
Things I tried:
(1) Uninstalled driver. Tried to reinstall driver using Dell Support Assist via website, got an error that it was forbidden by system policy. Opened up GPE via gpedit.msc. Go to --> Local Computer Policy--> Computer Configuration --> Administrative Templates --> Windows Components --> Windows Installer. Double-click Prohibit non-administrators from applying vendor signed updates, change from "Not Configured" to "Disabled". Installed driver, restarted, wireless adapter still not working.
(2) Shut down machine. Turned on, pressed F2 repeatedly until BIOS came up.
Made changes in BIOS - (A) Made sure WLAN & Bluetooth were checked under Wireless Switch
(B) Made sure WNLAN & BLuetooth were checked under Wireless enable
Restarted machine, wireless adapter still not working.
What eventually fixed it:
(3) Ran Dell Support Assist one more time & it showed there was one more urgent update needed, it was a BIOS update. Ran that, restarted. My WI-FI is working. I was able to click on wireless connections, select my Home Wi-Fi & add in the network credentials.
It's possible that a combination of everything I tried is eventually what fixed it.
