I have a MediaTek Corp. MT7922 running with kernel 6.2.0-20-generic
#20-Ubuntu. Wifi works fine after a reboot, but it does not start after
resuming. I can't even do sudo commands after resuming and the computer
won't turn off (I have to turn it off by pressing and holding the power
button)
The report here says that it works fine after suspend, but it is not the
case here. Any ideas?
$ sudo lshw -C network
