When my PC wakes from an overnight suspend, sometimes it shows as disconnected from internet and the only option upon clicking the icon is airplane mode, so i do that but it doesnt work, upon reboot its all working normal

My other PC uses wifi and thats fine and other devices connected via cable seem fine too

21h2 and latest drivers from WU

Thanks

The only other things I can suggest to try are:

Make sure you have latest lan and chipset drivers.

See if you have an available bios update.

Reset network adapters
Reset Network Adapters in Windows 11 Tutorial

Make sure you have no corrupt system files that is causing this problem. Open a command prompt as administrator and type sfc /scannow
Pay attention to the scan results to see if SFC found anything it could not repair. If it found corruption it could not fix followup with this command (note the spaces)
dism /online /cleanup-image /restorehealth
Restart computer
(Note-you can follow up with another sfc /scannow command to make sure that dism repaired the files)
