I am using Manjaro 5.15.94-1 in an HP desktop. Yesterday, I tried to update the BIOS, and I succeeded by doing it in WinPE. Unfortunately, after rebooting I found that I cannot enable the Wi-Fi card.
ip link show wlo1
3: wlo1: <BROADCAST,MULTICAST> mtu 1500 qdisc noop state DOWN mode DEFAULT group default qlen 1000
link/ether d2:7b:72:1c:8f:d8 brd ff:ff:ff:ff:ff:ff permaddr 7c:70:db:0f:8a:61
I tried to enable it by
ip link set wlo1 up, but it raise an error “RTNETLINK answers: Input/output error”. And there is no helpful message in
dmesg | grep firmware or
dmesg | grep iwlfifi. Any idea how to solve it?
BTW, I am using
Network Manager. Despite the Wifi is inactive, the wired connection is okay.
