I'm having trouble getting my wireless working on the Backtrack 3 live CD. I've tried this...

Code:

bt ~ # wlanconfig ath0 destroy
bt ~ # wlanconfig ath0 create wlandev wifi0 wlanmode ap
ath0
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...

Code:

bt ~ # wlanconfig wifi1 create wlandev wifi0 wlanmode ap
wifi1
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.

Try this

Code:

iwconfig ath0 essid nameofnetwork key whateverthekeyis
ifconfig ath0 up
dhcpcd ath0

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.

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
