The hardware has known issues:

There’s a driver package in the AUR that may help.


Tanks will try that.


I had the same problem with rtl8821ae. Installing newer drivers didn’t help me at all.

What did help me was disabling NetworkManager and connecting with netctl.

There’s a good instruction at Archwiki:


It’s broken everywhere.
Try to get help here


The guy here claimed to have solved tho…


since i installed kernel 413 it does reconnect back again, but i will definitively have a look into that tanks @mirh
