Hey, bro. What console are you playing on? Also, are you using wired or wireless connection?
Were you able to play the game before? If no then that might be an issue with match making. Match making is how you are being paired up with players. Connection and DLC ownership are reasons for matchmaking.
A support case was created for you and you should be contacted shortly by a Customer Support Representative, if you haven't been already. You can view and update your case at the Activision Support website. After logging in, go to "My Support" then "My Cases".
I Have the same problem. My signal also shows poor but on my ps4 it's perfect. I tried wired and wireless connection. I've been having this problem since downloading the revolution pack.
