Backtrack5 freezing after connect Wireless

[r0gerthat]

Hello everyone, I have a dual boot (with Win7) install of backtrack 5 r1 GNOME 32bits (kernel 2.6.39.4) on my notebook.
The system is working fine, and i didnt have any problems during the installation, but when I connect to the internet using a wireless connection, in the begin everything looks fine, I can access some websites, but some seconds/minutes later my Backtrack 5 freezes completely and I have to reboot the notebook.
OBS: Using a wired connection, I didnt have any problem

I searched alot about that, and I didnt find anything that could fix my problem until now.
Thanks for the attention.

Some additional info:
-When my network cable is connected to notebook, I can connect using wireless and got no problems, but if I remove the cable, my Backtrack freezes again. Could it be some conflict issue with drivers?
-Sometimes I had the error message from wicd: "Could not connect with wicd D-Bus interface", so I tried this to fix the problem:

dpkg-reconfigure wicd
update-rc.d wicd defaults

And my wireless connection worked fine, but after the first time I rebooted my computer, the freezes started again.
-On Windows 7 my wifi card is named Atheros AR9825 and on Backtrack Atheros AR9287. Could it mean something?

Hope someone can help me, cause im getting sick of this problem...
Thanks.

Since I didnt find any solution looking for this bug in backtrack, I started to search about this in Ubuntu, and finally I solved this issue.

Fix:

This is caused by the wireless driver, what I did was set Network Boot as the first option in BIOS. Hope it can help more people cya
