For a few weeks now, I kept having problems with my WiFi. Out of the blue, suddenly every minute or so a popup kept showing that he could not connect to my WiFi any more. Even if WiFi was not even in use because I was on cable network.
dmesg shows this message:
No beacon heard and the time event is over already…
I googled a bit, found lots of other people with the same problem, but no solution, and I had the easy ay out – the Windows method.
Today, I started to get angry, and searched again, and finally found the solution:
- Open
/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf - If it says:
wifi.powersave = 3– change this to 2
# Values are 0 (use default), 1 (ignore/don't touch), 2 (disable) or 3 (enable).
Afterwards, restart the network manager:
sudo systemctl restart network-manager.service
I hope this solves it, and maybe if you have the same problem, there is now one more place that lists a solution and not only the problem 😉
Many thanks to the german ubuntuuser forum where I found the answer: https://forum.ubuntuusers.de/topic/iwlwifi-no-beacon-heard-verbindungsabbrueche/
EDIT: Obviously, this did not work 🙁
