It's been quite some time since I've played COD but just recently I thought I would try and play it again. I got onto the game and once i tried finding a game, it sat searching and saying "we need to find 7 more players" for hours. I gave up on waiting and I tried joining a friends party but it says " the party is no longer available." I've restarted my router a few times now and sometimes it would work. When it worked I could get into 1 game but as soon as I left and tried joining another game, it would search and find nothing. It would go back to how it was before. I tried playing BO and the same issue occurs on that game. Any other game I can get online just fine except for COD. Any help is appreciated. Thanks.

-NAT type is open

-Wireless connection

*This is on Team Deathmatch and i'll try another game type and see how that goes.
