Well, I can't tell if I fixed the problem where it lags when searching for a new network. I did speedtest.net several times and discovered my laptop gets really slow speeds. Last night my speeds were fairly high though at 2.5 mb/s download and 450 kb/s upload.

My dad's xp laptop in the same vicinity as mine got 4 mb/s download and 400 kb/s upload. The hp millenium with direct ethernet connection to the router got 5 mb/s download and 500 kb/s upload.

I have tested and manipulated my laptop all day and the fastest speeds I have gotten were 500 kb/s download and 450 kb/s upload. I tested it far away and close with the same bad results. I also connected to a new n router in the neighborhood that was an open network and got the same slow speeds, albeit I barely got a signal on that one, so I can't be positive it's not my router.

This evidence leads me to believe however that it is my laptop with vista. I have fooled around with just about every wireless setting on my laptop. Any more suggestions?
