The good Doctor chili555 fixed my Wifi around 10 months ago http://ubuntuforums.org/showthread.php?t=2267853
But unfortunately it is playing up again.

I've tried different settings, Channels etc in the WiFi unit but it still goes slow and has a habit of dropping out. I have been following a few threads on the subject and I've now got 2 antenna's (one on each connector) on my card. It has improved the signal strength, but not the speed, which is painful at times.

I rebuild the drivers as per the good Doctor's instructions whenever there is a change to the Kernal. But of late I have been getting the following errors when running the code:

I have cut a lot of the code out. But, left in the Errors and Permissions Denied.
