Hello, which console are you using? The problem may be your internet connection suddenly goes poor. Can you try speedtest.net to tell us your download speed, upload speed, and ping? You may try using your console's web browser if using Playstation 3.
For Black Ops 2, it is very important to have the lowest ping possible, less then 50 ms, lower is better.
If you get too high of ping, the problem may be your connection to internet or your ISP (internet service provider).
What is your ISP?
Download Speed: 1.42 Mbps
Upload Speed: .88 Mbps
I have ATT internet, never been a problem.
I will say after giving it about 8 hours it is doing much better. But I am afraid this problem may arise again. There are 4 computers 3 phones and 1 xbox on my internet, but half of those are only on at atime.
Your download and upload speed is good enough for Black ops 2, as long as all other computers is not using the bandwidth. If the laggy problem happens again, go check other computers (stop the downloads) and possibly disconnect other computers from the internet.
You might try getting more download speed if other computers will be frequently downloading stuff or playing youtube videos. Higher speeds helps reduce lag problem when other computer downloads stuff.
As long as all your computers and phones isn't downloading or using the internet, you shouldn't see the lag problem. Does this information help you?
I've been finding and playing any match for 6 months now but I spend most of my time playing hardcore kill confirmed. On Saturday morning I purchased the Vengence DLC now when I try to play hardcore kill confirmed i spend ages sitting in a lobby by myself, I gave up after sitting there by myself for 40 minutes last night. I have tried going in and out of the lobbies, I can play other matches but not KC. Has continued all day today as well, I'm really gutted I can't figure out what is going on.
Can you please tell us the platform you are on as well as the type of connection you are running (wired/wireless)? Also, what is the NAT type that is currently registering in-game? Multiplayer> Options>System Info. While in Options, press the Select button (PS3) or the Back button (Xbox) on your controller and System Info will appear on screen.
I don't know much about the technicallities of this game, just like to shoot people lol, so please do bear with me.
Platform: No idea but going to take a wild guess and say Xbox? (please explain if I'm way off)
Connection type: wireless - note I am able to play any game type except hardcore kill confirmed, this to me indicates no problems with internet speed etc.
NAT type: Moderate
Any help is much appreciated
