I have been trying to set up my son's (since Xmas!) router so he can use his Xbox when I am online with the XP. We can each get online individually but it's a matter of who get's there first! Actually the xbox shuts out the XP as soon as someone plays it.We can't use the router at the same time. (which is why we got it in the first place!) We are cable/modem connected. It's a BEFSR41 Any ideas?
