[Bug 575844] [NEW] [lucid lynx][dell-wifi] Wireless Disabled for iwl3945

[Rajesh K. Verma]

Public bug reported:


Hi All,

I have Dell Inspiron 1420 with BIOS version A10. I was using Ubuntu 9.04 64-bit and had no issue with Intel 3945ABG wireless card.
Recently, I have installed Ubuntu 10.04 64-bit (fresh install) and this created the problem with wireless saying "Wireless disabled". I had the similar problem with Ubuntu 9.10 therefore shifted back to 9.04.

After googling, found some similar issues which were telling to remove
network-manager and install wicd.

But still, WICD was not able to detect wireless and could able to scan
the network only when network-manager was also present. One more weird
thing was, wicd able to scan and detect wireless connections only when I
connected the system with eth0 cable. After detection, I could unpluged
the ethernet cable and start using wlan0 connection.

Also tried by doing:
sudo rmmod -f iwl3945
sudo modprobe iwl3945 disable_hw_scan=1

http://ubuntuforums.org/showthread.php?t=1420053

But it also not worked for me.

After removing "dell-laptop" module and blacklisting the same, network-
manager starts detecting the wireless connections. wicd also able to
detect but sometimes starts asking authentication for startup (don't
know why). My system is running with default kernel (ubuntu
2.6.32-21-generic) came with ubuntu 10.04.

Could you please let me know, is there any patch available for this
issue for ubuntu 10.04. Also, what could be the side-effects of removing
dell-laptop module.

Thanks.
