Same problem on 360, except game takes very long time to connect then 'client desync' or doesnt connect at all, i have never managed to play for more than 2 minutes or so even when it does, meaning the game is totally unplayable. have run all troubleshooting and EA help had no explanation and also reffered me to their specialist team, i was told there was no problems with their servers or anything on their end. altogether this has taken up at least 6hrs+ of my time, let alone the time trying to connect over the last 6 days. After this they asked me to contact my ISP and get them to check/clean my line which i believed to be a 'pass the blame' attempt, especially considering all other games run with no lag, connection is at max and no other problems (i always seem to be host for black ops 2 online games which chooses the most adequete host for example). After contacted my ISP they replied with this:
'I have traced the same connection you have and found no problems in the UK end of the connections either with us or our supplies, however I did notice the address 159.153.93.2 drop out when I conducted the test, I have since used the IPlocation.net website to find the location of this address to help determine the fault in the connection, the fault is somewhere in Redwood City, California, next to the EA Games HQ.'
Strange that, so EA still sure there is no problems with your service? I believe otherwise. im am now returning this game as faulty due to these problems. I do however fully believe if i re-bought the game in a few months there would be a fix, i just dont understand why EA had to denie there was any problem or cant tell themselves the problem is present. so either lies or stupidity and theres certainly no excuse for either at the cost of our time and money.
