you have 2 options with that on the configuration. "this connects me to:" 1. Internet, and 2. Work.
I think you have to set it on "work."
when you have it on "work," though, the MSN messenger asks me to have the proxy set up. when I have it on "internet" it just connects me right away.
I haven't retried this... because frankly there wasn't that many occasion for me to sync away from the computer... as I mainly sync for new software installation...
But one cool thing I can do with wifi is put a movie file on the computer's shared folder, access it with resco file explorer, and stream/play it through wifi.
Battery drained faster than charging, on a pretty low brightness setting.
I just wanted to try it. 
I'm not sure how so many people can overpower the charger so easily, I have to be on max light ad cpu speed, running about 8 programs and have both wi-fi and bluetooth on before it gives me the warning.
