Ok first of all when I'm not having major problems as I will list in a bit the router is actually not that bad fast connection speeds and all.
The first problem I had is that the Internet would disconnect out of the blue at various times no matter how many devices are connected. I thought it could just be my Internet cutting out however I plugged in my old router and it worked fine. Also all the lights on the router indicated that it was receiving the Internet connection and nothing was wrong. I would have to unplug replug the router to get it to work again. Belkin support is terrible when I tried to email them. When I found the problem listed on other sites Belkin says it isn't the modem but its your ISP (Internet service provider), well that's not right since my old router worked fine.
Any who second problem was with Xbox live NAT restrictions, I found the best way around this was to just access your router on 192.168.2.1 and allow a DMZ on your Xboxs ip address found on the console (network settings).
If it weren't for the mainly first problem I would of given it a 4 or 5 star rating.
Hope this helps anyone.
