I have a wired Xbox 360, although I have a few friends that I cannot join their party or their games. I have looked this up and tried restarting the modem and router, adding opening ports in my router (80, 3074, and 53 or something similar to this). I don't get any NAT messages and on COD it says my NAT is open. The strange thing is at one point of owning my Xbox, I was able to join a certain players party, but now I can't. I also heard it can be my modem being the problem. I have a Motorala MIPDSLA, and a Cisco Linksys E1000 router. My Xbox is wired. If anyone has anything to say ill try it, I've had this problem for almost a year now and it's getting frustrating because I now I'm left out sometimes because of my internet. Someone please help me.

I think I have a static IP setup from a while ago, and yes, I was thinking that it could be on my friends side. Then again it is happening to multiple people and they can all join each other.
