Me and one of my friends can't connect to eachother. This has happened once already between us, but all we had to do was fix his NAT. But one day, it just stopped working, both of our NAT's are open and it still won't let us connect. The only way I can connect to him is if I take my ethernet cable out and put it into the main internet modem. The problem is if I do that it disconnects my brother since he uses the wireless and use the router with the cable directly connected to the wireless router. I use a ******-G-Wireless router and he uses his main internet modem.

If this helps I'm just going to tell you that I live in Canada and lives in Utah.
