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
so i tried iwconfig wlan0 and gotError for wireless request "Set Mode" (8B06) : SET failed on device wlan0 ; Operation not supported.
So the Mode is forced to Managed instead of Ad-Hocwlan0 IEEE 802.11bgn ESSIDff/any Mode:Managed Access Point: Not-Associated Tx-Power=19 dBm Retry long limit:7 RTS thrff Fragment thrff Power Managementff
So, where do I go from here?
The output for sudo lshw -C network is
