Wireless connection manager

[kenny320]

Hey everyone
I'm having a lot of probs at the moment with my wifi connection. It keeps dropping out due to the presence of another wifi network and can't decide which to connect to, even when i tell it. I was wondering if anyone knew of any good software for managing wifi connections so i can tell the machine only to connect to one specific network? Or are there other possible solutions?

Cheers people, I know PH will find an answer
