Our son is heading off to UW-Madison and making a list of things to bring. Their internal network web page has suggestions for WAP and they list DI-614 and WRT54G.... We have all Linksys stuff at home and it's been ok.
What type of wifi is his eqpt. capable of 11a,b,g..N? What level of encryption is the lowest common denominator in the eqpt. he is taking, it is a college so WEP will probably be hacked and he will still be responsible for other users on his WAP. "Note: Any computers connected to ResNet through your router or wireless access point are your responsibility. For example, if a computer in the room next door connects through your wireless router to ResNet and becomes infected with a virus, the router will be quarantined until the infected computer is cleaned."
If you have a router at home that is not to old I would give him that to use for the first term and get yourself a new one.
