I am a newbie to Ubuntu, and loving it except for this AdHoc issue which has been bugging me for a month. I have found numerous posts on the issue with no real solutions, so let me be a bit more specific regarding the issue, and hopefully someone can help me out.

I have a Broadcom Driver on a Dell Inspiron and the Wifi works great. The AdHoc works on a parallel installation of Windows 7, so that should mean the card supports AdHoc. My friends laptop running 11.10 is able to connect to the network via Adhoc with no issues, hence the network is setup right. Of the many things i have tried so far, I got the ndiswrapper, tried all possible configurations (manual configuration) in network manager, even tried the wicd manager

The latest breakthrough was when I tried sudo iwconfig wlan0 mode ad-hoc

Error for wireless request "Set Mode" (8B06) :
    SET failed on device wlan0 ; Operation not supported.

so i tried iwconfig wlan0 and got

wlan0     IEEE 802.11bgn  ESSID:off/any  
          Mode:Managed  Access Point: Not-Associated   Tx-Power=19 dBm   
          Retry  long limit:7   RTS thr:off   Fragment thr:off
          Power Management:off

So the Mode is forced to Managed instead of Ad-Hoc

So, where do I go from here?

The output for sudo lshw -C network is

I have upgraded to 12.04 Precise Pangolin and it is now working great. Haven't been able to spot the initial issue, but with this upgrade, it dosen't matter now.
