I disconnect when i try to play Campaign or Spartan Ops with others
it is probably your internet, go to http://www.speedtest.net/.
If you have a high ping, low download and upload then you have a problem. Talk to your internet provider and tell them you can’t play online. They should fix your problem
some more info would be nice…does this only happen with h4 or with every game u play?
before u call ur internet provider, i rather u to try some other things first
try to redownload your profile
if this doesn’t work try to clear your harddrive system cache
btw do u use wireless or cable?
