Okay, this may be an old thread but it was a new problem for me. If you are here, you have had the same problems I have had. I tried everything I found on the net to fix the “Your connection to the server has been lost” problem, and nothing seemed to work. Even my ISP got sick of sending out techs to check lines, modems, boxes, etc. I had just completed a new build and everything was the same except, I installed an AMD64 x2 4400+. After trying every thing that I found, I quit playing for weeks just furious. Then I remembered one tip that I did not try. Changing the CPU Affinity setting in the Task Manager. Well I did, and now I have been playing for two weeks without a connection loss. Now this fix may not work for you, but give it a try (if it applies to your CPU). If it helps some players, well then it’s a small victory. LOL Anyway, if you have not found the previous posts on it here is how you change it. Start up your BF2 as normal. After the game connects to the Account Server, Alt+Tab out to your desktop. Then, Ctrl+Alt+Del to Task Manager. Under your Processes tab, find your BF2.exe and right–click on it. A small menu will pop up and at the bottom is “Set Affinity”. Click on that and a small Dialog Box will open. There you will see CPU0 and CPU1. Uncheck CPU1. Hit OK and close your Task Manger. Go back into the game. Now I am computer Savvy, but don’t claim to be a PC Tech so if it does not work for you, well I am sorry and good luck finding the right fix for you. P.S.- The other threads were over 30 Dyas old and locked so plz don't complain that their are other threads about this. None I saw had a fix.

I didn't make it!
You do realise theres a patch for just that problem ? For 64 bit and 32 bit . Its been out for months now, it allows both cpu cores to still thread bf2, dont get me wrong the game isnt coded to take advantage of 2 cpu cores, so it will not improve the game code program, but it will take out all the ' chop chop' you no dought must have also been suffering.l dont have a link, try the AMD sight. But yes affinity set is just as good, however for ppl in general its to complicated to stuff around with, also, its a matter of doing it for everygame you play without the patch. Some games like v8 race driver, run at double speed with 2 cores running it, they go ballistic, ever driven a v8 at 530 kmh ? Bit choppy but funny to have a mess around with, unbelievable FRAPS footage, rather funny, you hit the straight, con rod, and 2 seconds later, 2 seconds, your in the wall at the other end of the straight ! Anyways go find the affinity patch. Dual core patch.
Where is this patch as i have been having lagging problems with the game and found out that unchecking the 2nd core works however is annoying having to do this all the time. I have the officel 1.22 patch installed also.
Well i was getting a connection problem evey so often however in another thread this worked fixing my fps problem i was having more then quadropling it.
