wireless Atheros AR9485 on hp 655 and suse 12.2 don't work

English Network/Internet
1

on my notebook HP 655 shipped with suse SLED11
processor=AMD E1-1200 APU
with radeon HD graphics 1.40GHz
32bit 2core processors
fresh install of opensuse 12.2 with kde

my Atheros AR9485 Wireless seems to be recognized but don’t switch on,
I checked if the wireless works installing windows and looking for the proper driver (quite complicate :-)) ) it works,
is there a keystroke(F12) in the keyboard (to press with or without “fn”) to enable wireless, in windows isn’t need to press it, in suse pressing it has no effect
I looked in BIOS but there isn’t any item about enabling or disabling wireless

how can I solve??

thanx, ciao, pier :-)))))

following your very useful sticky :
1)=ok, 2a)=no usb wireless adapter,

For each interface that does not support
wireless the result is “no wireless extensions.”

It seems solved, taking into account this link that says “blacklist acer-wmi”, I looked in my lsmod output and I tried to blacklist my “hp_wmi” in /etc/modprobe.d/50-blacklist.conf, restarted , now it works, :-))), at ther first start result off, but at the first press of f12 it becomes on, I don’t know what hp_wmi does, may be I will discover other things don’t works…

I am getting the same results…it says blacklist is read-only…and when i try in the terminal it says modprobe :command not found

You need to edit all files in /etc as root. Use ‘kdesu kwrite <file_name>’ if
you use KDE. For Gnome, there is a similar command. Never log into the GUI as root.

The use of modprobe must also be done as root. In the terminal, you can use
‘sudo /sbin/modprobe xxxx’.
