Zombies Server Disconnected Every Other Attempt

[vertin]

Whenever I try to play zombies solo or with my friends, every other attempt ends up getting a server disconnect. I'm not sure why this is happening. For example, I can play 1 game and the next game will do a server disconnect and the next try will work, then the one after will disconnect etc. My computer should meet the requirements and I find it odd that it is always every other attempt failing.
