I was trying to run airbase-ng on my laptop’s Ubuntu 10.10 but I realize that it have problems. (1.) The created Access Point could not be accessed and (2.) the channel that the Access Point is created runs on channel 255 which is out of range. I had to start searching for a solution. My early findings told me that it had something to do with the network driver. My laptop runs on bcm4311 and I found out that it may have something to do with MadWifi so I thought I need an Atheros. This morning I had tried firing up my laptop in BackTrack 4 and ran airbase-ng. My iPod caught the Access Point immediately. At this point, I knew that it must be something wrong with Ubuntu so I continued searching.
I had then found out from the internet that it could be my kernel version that is causing the problem and here I am, updating my Ubuntu from the default kernel 2.6.35-22-generic to 220.127.116.11.
Whether or not airbase-ng is going to work now I am still not sure, will be updating this. It works.
