Are all your friends you play online with, within the same country as you?

It depends how close the server is to your location, too far away your going to lag and get only a few bars.

Also it can be a server issue too, I've had it go from the 4-5 bars I normally get down to a pathetic 2 or even 1 bar sometimes (usually very late at night though).

    So could be my internet is slowing down then and/or ALOT of internet traffic at that time of night.

Also what is your ping and are you using a wired connection, I highly recommend using cat 6 cable for the ethernet cable, so you don't get a loss of signal strength.

Just this minute tested my connection with a speed tester that my ISP uses and has come up with:

Ping: 26ms   

Download speed: 8.91 Mbps

Upload speed: 0.76Mbps

Not sure how good my upload speed is at the moment, but my download speed and ping looks to be pretty good.

I think most of us are having the same issue. This game has been out since Nov. 2011 and the Server/Lag issues continue to grow. Only thing I ever hear from anyone with the answers is we will forward this to the appropiate channels or go reset your router. I am tired of all the excuses, I am not stupid (questionable) I am using a wired connection with 14MPS DSL service I live 2 blocks from my DSL server office and my connection on other games do not have this problem  So my question when is activision, beachhead, Infinity ward and sleghammer games going to stop tweaking the game and start fixing the major issues like lag, connectivity, spawning, among many others?
