iwlist ath0 no scan results

I'm having trouble getting my wireless working on the Backtrack 3 live CD. I've tried this...
bt ~ # wlanconfig ath0 destroy
bt ~ # wlanconfig ath0 create wlandev wifi0 wlanmode ap
bt ~ # iwconfig
lo        no wireless extensions.

eth0      no wireless extensions.

wifi0     no wireless extensions.

ath0      IEEE 802.11g  ESSID:""  Nickname:""
          Mode:Master  Channel:0  Access Point: Not-Associated
          Bit Rate:0 kb/s   Tx-Power:16 dBm   Sensitivity=1/1
          Retry:off   RTS thr:off   Fragment thr:off
          Encryption key:off
          Power Management:off
          Link Quality=0/70  Signal level=-256 dBm  Noise level=-256 dBm
          Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
          Tx excessive retries:0  Invalid misc:0   Missed beacon:0

bt ~ # ifconfig ath0 up
bt ~ # iwlist ath0 scan
ath0      No scan results
...and similarly, this...
bt ~ # wlanconfig wifi1 create wlandev wifi0 wlanmode ap
bt ~ # ifconfig wifi1 up
bt ~ # iwlist wifi1 scan
wifi1      No scan results
...and other similar things, but they didn't work. Can anyone tell me how to get my wireless working? Thanks.

Thanks for the reply but it didn't work. Also I would need scanning if I didn't know the essid. One more note I don't know if it matters or not... I have to boot into text only mode with noapic and acpi=off then I can startx. Any ideas?

What type of card? Have you had it working before? Are you close enough to an access point/router?

It's an Atheros AR5007EG on an Acer Aspire 5520 laptop. The only linux I've tried so far is Backtrack 2 and 3. Didn't get it working in either one. It works in Windows Vista. Definitely close enough to an acess point.

Smile Press the hardwired button

There´s a hardwired button on your laptop which turns wifi on/off, press it, as soon as you turn on your laptop, when the bios screen comes, and that should fix it. I had the same issue with an acer 4520
