I'm running Vista Home edition on my laptop and when I use my laptop
at home, it keeps on connecting to an unsecured default wireless
network, instead of connecting to my home network, which is named and
is secured. I guess one of my neighbours decided to just run their
wireless network like that.

How can I prevent my laptop from connecting to other networks other
than the ones I specify? I've looked in the settings and options in
the wireless connection management utility in Vista and couldn't find
a way to do that. Perhaps i didn't look hard enough, but would
appreciate it if someone could provide a solution to this issue.
Thank you very much for your time and courtesy.
