Yesterday it was fine. Today I booed into the system, didn't check wifi status (usually it's connected during the boot) and closed the lid, which triggers suspend action.
When I opened the lid, there was no wifi connection. Network restart, reboot, hard reboot - none of it worked. It looks like if there were no wifi connections around or as if it wifi was on but didn't try to search for networks.
I checked into my Windows OS which I haven't booted for over a half year and the wifi is working fine, so that is not a hardware failure.
I'm using unstable branch lately so I thought this may be caused by my recent systemd 455 craziness that I complained about in the Announcement section. I couldn't switch to resting and downgrade because of some file ownership and dependency issue:
The lack of internet is a show stopper so I restored my backup from a few days ago 7.03.2020 with systemd 244 and... no change, the wifi is still not working.
Since this wasn't caused directly by some package versions, maybe some config went corrupt, I don't know. I'm writing from my Win 10 , because Manjaro without Wifi is not usable for me. I don't have long enough cable to use it normally.
Please, help me to figure this out. I'm not familiar with networks.
I'm posting some VERY OLD inxi output that I bookmarked and posted elsewhere because at the moment of writing I'm on windows, so ignore software related info which is clearly obsolete:
