I just got a new xbox 360. I have owned my ps3 since they first came out and since then, i have got a NAT strict problem. I started the xbox up and same problem. Im starting to think its my router. I have the linksys WRT160N v2. I have tried everything from Upnp, opening ports and DMZ but none have worked. So i am looking for a router that fits the NAT open and supports Upnp with good range and speeds. Any suggestions?
