Vista - too many wireless networks

I'm thinking this is a common theme here...
On my old laptop {XP} I have no problem connecting to my wireless network.
I'ts secured, and I get a strong signal.

On my new laptop {Vista} I connect easily to the wireless at work, but at
home it's impossible. I suddenly can see half a dozen networks around me,
including mine, but it keeps dropping me. Then it keeps trying to connect me
to another unsecured network. At first I thought it was some dude in the same
complex named belkin who didn't secure his network, but I noticed someone
else here was writing about a belkin router {that made me laugh}. My network
signal is really weak on the new laptop too,before it drops me.

Is this a Vista issue?
