[SOLVED] NetworkManager fails to connect to WiFi

Sweyn78 · 2019-05-20 08:33:16

NetworkManager is failing to connect to my WiFi.
I'm on a fresh Arch install. I'm dual-booting with Windows, and Windows is able to connect to my WiFi. Likewise, LiveCDs of other Linux distributions are also able to connect to my WiFi.
I have verified that I am using the correct password.
I am attempting to connect to one of the stock routers AT&T provides.
Also, fwiw, ethernet works fine. However, as this is a laptop, having functional WiFi is pretty critical.
I've just spent an hour searching for solutions, but I've had no luck. I'm hoping someone here might know how to get this working.

Here's the relevant portion of journalctl:

a dmesg after reproduction of the issue? FWIW NetworkManager often has issues with it's internal DHCP Client (though it doesn't look like you are even getting there), try something else

A full dmesg please, lots of context missing in these greps.

Unfortunately, those weren't greps -- those were solid chunks I excised by hand. I would provide you with a fuller dmesg, but it seems all the other setup I did must have magically fixed NM. I have no clue what it would have been, perhaps one of the following? [1] installed base-devel (Maybe NM was missing some undefined optional dependency?), [2] switched to linux-zen (Maybe there's something in this kernel that magically fixed things?), [3] installed bluetooth (They're technically the same radio, so maybe this somehow installed something I was missing?).
Anyways, thanks for the quick reply.

I have the same issue i have a dual boot system with arch and windows 10 and this issue occurs when i put my laptop on sleep or when i turn it on the solution to this is restart the pc but i am not satisfied with that.
the output of :-sudo systemctl status NetworkManager
