This is more of a [HELP] Question, but I want people to discuss what they think about this shit.
I was playing MW2 all fine until the next day my NAT becomes Strict, yes I can still play, but if I try inject my Lobby tools I can't find a game, I can get into a game and inject it but then in the lobby it won't start the game for any of us and I eventually "Unable to find host".
I check Infinity Ward's NAT Help and it basically just tells us to have our uPnP enabled, which I do when I checked my advanced settings on my virgin media, but I'm wondering if the problem is, I use a powerline adapter (Click for my model)
Some of my games seem to have NAT Open though, I don't know why but they do.
Discuss what you hate about this problem (also suggest possible fixes)
I have to disable and re-enable my Local Area Connection to have an open NAT type, Try that. Works for me every time.
Restart you computer, sometimes mw2 say,s strict when you nat type are open. log out mw2 then two or three times log in mw2 then nat type are open. when strict u can use lobby tools only in free for all , deathmatch gives an error.
