I have a Sony Vaio Fit 14 laptop with a Broadcom integrated WiFi adapter which never worked on Ubuntu/Mint. Therefore I have been using a WiFi dongle with a Qualcomm Atheros chip.
I've installed the Manjaro i3 community release. During the installation, the Broadcom adapter didn't work, but that didn't bother me. I can keep using the dongle after all.
After installation finished, I plugged in the dongle and tried to connect to my network. By default, the Broadcom adapter (which does not work - it asks for the password indefinitely) is selected.
My problem is: When I change it to Qualcomm Atheros, the field to type in the network password disappears.
The Broadcom is displayed as status "dormant" and the Atheros is "down". I tried
sudo ip link set [atheros-name] up but it stays down.
I'm going to try and get the output of
inxi -Fx and paste it here as a reply in a moment, since I'm writing this from Windows.
Please let me know if you need anything else, and thank you very much for your time!
