I just recently fixed my broadcom driver and it seemed to work out perfectly but when I get too far (about 10 feet away) it automatically disconnects and tries to reconnects again. When it does reconnect the internet is really slow and the process just repeats again. When I was running Win8 this wasn't a problem so not sure if the router is the problem.

Anyways here is my "wireless info script"
