Which other information do you need?

Do you have the NIC?

ip a

Bluetooth could interfere w/ a 2.4GHz carrier.
Other than that, cut out NM and test "by hand", https://wiki.archlinux.org/index.php/Ne … ireless#iw

We're probably going to need the system journal (on whether there're eg. firmware issues, NM just stumbles over itself, …)

For instance, now it connected immediately to my network, after rebooting from Windows: maybe a stand-by or activation related issue?
Anyway, in the following you can find more informations:

Which journactl log do you need? Could you please give me the command?

seth · 2020-11-03 16:39:32

"sudo journalctl -b", but

after rebooting from Windows

first check the third link in my signature...

If you have MAC address randomization enabled in Network manager try disabling it.

Try blacklisting bluetooth to see if that makes any difference.

It might also be worth testing out the LTS kernel.
