Tried it all, reboot, xbone and router, power cycle both, nothing works, some things get me strict or moderate but i was open on both console and game for months and now im still open on XBONE but moderate on Ghosts, its been like this since minutes after the 3gb patch !!
I'm in Germany and after the 3gb patch the other day my ghosts NAT has changed to moderate. Not tried to fix it yet, but as I haven't done anything else, it has to be the patch!
My console is set to English, not sure if that has anything to do with only getting the update on the 4th, even though in in mainland europe.
Who knows!! certainly not I
I've been having unstable connections, too. Weird deal.
