Yesterday I upgraded from Ubuntu 12.10 to 13.04. I absolutely loved it until I realized the wireless connection would only last for about five minutes and then become unusable. I searched all over and ended up trying this and this. Nothing was working so I eventually reverted back to using 12.10 and everything is working great again. I would love to be using 13.04 right now so I am asking for help with this issue.
Here is some of the info I got for my system after I re-installed 12.10, let me know if any other information would be helpful. Thanks!
