<p>You absolutely can, except for in IV! Policy started this year (fall 2009). I currently have a completely legal one in my room. There are only two issues with it. One, Resnet will not help you set up or troubleshoot a wireless router at all (my dad is good with computers and set it up for me, because I break everything I touch). Two, you should make sure to set a password or only allow certain computers to access it, else you could run into security issues.</p>
