Internet stops working after updating to 21.2

After updating to the latest version, Manjaro 21.2 (Qonos) the internet just stops working a couple of days later. I rolled back the update and then tried after a couple of days, but still, the same thing is happening. Right after the updating, it works fine but I don’t know what causes it suddenly stop working, where should I look for clues?

Then I doubt your issue has anything to do with the update.

Logs are always a good place to start, check your journal for errors since last boot when this happens:

$ journalctl -b -p err

I have updated twice and rolled back twice. And before this update I never faced this kind of issue in any distro I have used. So I thought there was a issue with the update.
