Bug Description
Wifi has very bad connectivity in this system.
Some of behaviour I am experiencing:
* During the connection (specially visible on video calls) it seems that the connection loses packages. This is on-going and it happens all the time.
* Every ~10 minutes, the connection is completely lost during 15 seconds, and then it reconnects again. When that happens, the following messages show in dmesg:
[ 2274.914647] wlan0: deauthenticating from a0:21:b7:d9:c4:23 by local choice (reason=2)
[ 2274.917456] wlan0: authenticate with a0:21:b7:d9:c4:23
[ 2274.919021] wlan0: send auth to a0:21:b7:d9:c4:23 (try 1/3)
[ 2274.919950] cfg80211: Calling CRDA to update world regulatory domain
