Edit: I'm noticing that this thread has gotten a fair few views but no responses, I'm now wondering if I have a really obscure problem that no one knows how to fix. It wouldn't be the first. As a result could someone let me know if they have a look through the problem and don't know what the problem is as that would also be useful information. Thanks.
Hi,
After running Ubuntu 9.10 with my wireless connection for the past 9 months it decided to stop working. It still works on a live CD however (Mint Julia), so I'm pretty certain it isn't a hardware problem. I have posted all of the information requested in the HOWTO thread.
I can still see the networks however I can not connect to them.
Any help would be appreciated.
Thanks.
