WRT310N and XBOX Live

Question

I recently installed a new wireless WRT310N. I have one computer hard wired to the router (Time Warner-Roadrunner) and 2 that are wireless, all working  with no problems. My son cannot connect his XBOX "live". We keep getting a message "IP address failed."
The people at XBOX are telling me that the 310N is "too advanced" at this point and they can't support it. They say I could connect by using an ethernet cable from the router to the XBOX but since these are in different rooms of my home, it isn't feasible without running a lot of cable. Has anyone else experienced this and does it make sense that the 310N is "too advanced" to work on a wirelss connection with XBOX?
