So I recently installed arch linux on a brand new computer. I used a wired connection but now I would like to switch to wifi. However I have not been able to get it to connect (although networks do show).

$ ip link

link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

$ lspci -knn | grep Net -A2

Not sure what to do. Tried wifi-menu, iw, netctl and networkmanager. Unable to connect no matter what I try. Access points show though. The network I'm attempting to connect to is found.

    Connect manually; it will provide more detailed debugging messages when it fails.

  • Try lspci -k to check if the driver for your PCI-card has been loaded. Check kernel messages for firmware being loaded: dmesg | grep firmware Also run rfkill list to see if your wlan is blocked (either soft or hard). If softblocked use rfkill unblock wifi.

when you run NetworkManager, then you can configure your WLAN with it and then have a log at /var/log/syslog or /var/log/messages and see what NetworkManager is doing and where it's failing.
