"No Wi-Fi Adapter Found", iw dev yields no results

light-tuna · 2018-09-16 19:50:47

Hello! It's been a while since I've used Arch, so bear with me.

I've recently installed Arch with Gnome 3. While my wireless initially worked fine, after performing a full system upgrade my wireless network adapter ceased to work. The Gnome settings panel tells me "No Wi-Fi Adapter Found" and I can only connect to the internet via ethernet.

I don't see my wireless card when I input

lspci -v

(I'm temporarily using an ethernet connection to post this)

Furthermore, entering

iw dev

lists nothing.

What can I do from here?

What is the card?
