ath0 scan shows no results

Hi everyone,

Thanks for reading this.  I have Arch Linux installed on a Thinkpad T400.  It has two wireless devices installed.  The first device came with it:  A realtek 8172, which as of right now has zero linux support.  The second is an Atheros 5001 which I purchased and installed.

First let me say that I've blacklisted both ath5k and ath9k.
I'm done: sudo rmmod ath_pci and then sudo modprobe ath_pci

I've made sure that the card is up.  I can see it in iwconfig and ifconfig as ath0, but when I scan from it I get no results and it fails to connect.

iwlist scan:

[user@sleeve-eater ~]$ iwlist scan
lo        Interface doesn't support scanning.

eth0      Interface doesn't support scanning.

wifi0     Interface doesn't support scanning.

ath0      No scan results

(sudo iwlist scan returns the same results.)

ifconfig ath0

[user@sleeve-eater ~]$ ifconfig ath0
ath0      Link encap:Ethernet  HWaddr 00:1D:D9:77:73:E4  
          inet6 addr: fe80::21d:d9ff:fe77:73e4/64 Scope:Link

03:00.0 Network controller: Realtek Semiconductor Co., Ltd. Device 8172 (rev 10)

If you look at the iwconfig output, it shows -96db.  Could that honestly be right?  Thank you for reading any input to help me fix this would be most appreciated.

Re: ath0 scan shows no results

sorry for solving your current issue but i just finished installing a NATIVE linux driver for the rtl8192 nic!  right now im using debian sid with the latest kernel release, so i think it'll work just fine under arch.
Im currently testing it... so im not sure if has any problems or so.
