Ralink Rt73 - No wlan0 interface with latest kernel *

Question

So, I update my kernel and I can no longer use my wireless card. It's not listed with ifconfig even though I'm loading all the necessary modules, those being: rt73usb, rt2x00usb, rt2x00lib
I have no clue where I can go from here, besides downgrading the kernel...

Answer 1

so, i am new to arch linux; passed thru gentoo and bored looong time debian user.
1) i'm experiencing the same problem, here on Dell vostro1400, iwl3945
# uname --all

2) [url href="http://bbs.archlinux.org/viewtopic.php?id=82277"]This url[/url] is not useful: my rfkill switch works as it changes its /sys/class/rfkill/rfkill0/state values 0 - 1;
3) sometimes wifi-led respond sometimes not, maybe related to boot with switch close/open; bios settings supposed ok (as on debian, where all the stuff regularly worked)

4) some relevant site on /etc bind with bootup stuff or touching /proc ?
5) 1) seems i don't have a binary called rfkill. i'm googling for AUR, any hints?
