The hardware has known issues: https://forum.manjaro.org/search?q=rtl8821ae

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


#3

Tanks will try that.


#4

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:
https://wiki.archlinux.org/index.php/Netctl


#5
