Hello....

I am trying to get an Atheros wireless (sticker says AR5B91, chip says 
AR9281) to work.  It is detected, but can't set ssid, scan, etc.  Source
is RELENG-8 from yesterday afternoon.  This came in a cheesy ACER 
Aspire 5735Z.

--- ifconfig shows only the following:

         ether 00:23:4e:3b:2d:9e
         media: IEEE 802.11 Wireless Ethernet autoselect (autoselect)
         status: no carrier

... if I try an ifconfig up, it says up:

ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 2290
         ether 00:23:4e:3b:2d:9e
         media: IEEE 802.11 Wireless Ethernet autoselect (autoselect)
         status: no carrier

... but always shows no options, ssid, etc.

All attempts to set anything say:

ROOT beast:/home/drussell 3 > ifconfig ath0 ssid MyNet
ifconfig: SIOCS80211: Invalid argument

Does anyone have programming docs for the 9281 and know what might be 
different from the 9280?  It has the same pci id but perhaps different 
subdevice, etc.

Looks very close to working....  DOH!  :)

Any ideas?

Full dmesg, etc. available if needed.

Thanks!

Later......						<Doug>
