[SOLVED] USB wifi adapter not working in Arch but ok in Ubuntu?

I have a Legion 9 and the internal MediaTek wifi (7927) is not supported in the latest Kernel (I'm using 6.17.5-arch1-1). Anyway, i have an old USB Wifi adaptor that works on Ubuntu 24.04 but when I plug it into my new Arch setup nothing

Here is the output from sudo hmesg -Hw when I plug it in:

[  +0.025549] usb 1-4: ath9k_htc: USB layer deinitialized

and lsmod | grep ath9k_htc gives me:

cfg80211             1421312  4 ath9k_htc,ath9k_common,ath,mac80211
rfkill                 45056  10 ath9k_htc,bluetooth,ideapad_laptop,cfg80211

So the kernel module is loaded? Not sure why this is not working...?

Also what exactly does "not working" mean?

Re: [SOLVED] USB wifi adapter not working in Arch but ok in Ubuntu?

Haven't tried the LTS kernel. I'll give it a try. Given that the Legion 9 is very new I was going for the most recent stable Kernel.

By not working, I plug in the USB adaptor into the USB port and the light goes on but does not flash, so no network traffic. I assumed once the right driver was laoded it would start to be used...? Do I have to manually configure the network setup somehow or setup routing tables?

Depends on your definition of "manually", but you'll need to install/enable some network configuration service, https://wiki.archlinux.org/title/Networ … k_managers
nb. *ONE* service!
