Unable to connect ethernet, just wireless connection

My kernel is: 5.13.6-artix1-1

The output of dmesg is:

$ sudo dmesg | grep r8169
[ 3.114305] r8169 0000:04:00.2: can't disable ASPM; OS doesn't have ASPM control
[ 3.118021] libphy: r8169: probed

[ 4.848435] r8169 0000:04:00.2 eth0: Link is Down

where eth0 appears as "Link is Down"

I've tried to use dhcpcd but it doesn't help.

You could try setting it 'up' manually and see if that works, or if you get some error messages that might give more of a clue:

Code: [Select]

$ ip link show
# ip link set enpXXXX up

There is troubleshooting info for network connections on the Arch wiki that might help (saying vaguely) ...
