I even tried rebooting again and the problem is still likely fixed. I will monitor the situation but for the sake of sustainable solution, I guess the above does set a setting that we could not set in any other way? It seems to work and that's great, I just wonder if running `sudo iw wlan0 set power_save off` upon each reboot or kernel update can be replaced with something more long lasting.If you use network manager as WiFi controller, set 'wifi.powersave = 2' in config file [1].

So I applied this with the wifi card failing again with the above errors. Then I tried the same NetworkManager config but with a full reboot and the wifi crashed again. I reissued the previous `iw` comment to set this but then the wifi crashed again before and after additional cold reboot. I am really not sure what is going on here. Should I look for more logs once this happens again despite the powersave mode? -- Best, Plamen Dimitrov
