I am having the same problem with my PS3 and MW3 system starts to download the update and locks up, then I get an error message, shut down restart, don't get the update screen but get a new error message. Rebooted modem and router that is not the issue, put in black ops disc and it works fine for multiplayer something is very wrong with the MW3/COD servers and or the update. This issue is NOT on my end with my internet set up or PS3. This is serviously aggravating..........all the money Activision makes off of this series of games and we the buyers deal with continued issues with COD servers, game glitches etc... pretty sad. As to my internet provider it is Time Warner Cable I am running their fastest internet set up which is wideband.
