Linksys and D-Link make devices (wireless access points) that will allow any wireless laptop to connect. They are occasionally on sale for as little as $9.99. The 'b' speed is the slowest. You should get at least the 'g' speed as in 802.11g. Your laptop will indicate it's speed somewhere in the documentation.

   If you lived off campus, I would suggest just buying one. However, for a dorm room, I would ask the school, especially the people at your specific dorm, for suggestions. Too many devices, especially the newer faster pre-standard devices, will interfere with each other. A couple of devices on each floor may be enough for everyone to use. The upper class students may already have enough bandwidth so that you do not need one.
