Yeah, the Rasberry Pi doesn't have Wi-Fi (as far as I know) Hopefully, they'll add that on their next model. (and how come the moment I log off, EVERYONE starts posting here?)
You have to get a dongle for wifi, but I have had power problems or super complex setup problems because of lack of power in the usb, very annoying to set up, I havn't won yet.
Also you can ssh in and set up internet sharing with an ethernet cable BUT IT WILL NOT WORK ONXP SP3
