This may be some thing to do with the new updates but... when I lose my connection my game will freeze every other person but me. I can run around, hack at enemies and they just stand there, other players some times vanish, but usually they just stay motionless. This will take place for up to a minute, and usually I don't catch it because I'm in "pirate mode" mentally, but after that my game will quit, and I have to reset my modem.
Side Note: I recently had a ton of trouble with my connection being lost while in the middle of doing some thing online, and had to call my broadband provider and have a service tech come out. Just for good measure I checked all my connections, even reformatted my PC... still the same issue. The guy came out, looked at every thing and was perplexed... He noticed I was using a modem I got about 5 years ago, (from him, he came in and hooked it all up when I first ordered their service... cool guy by the way) he went out to the truck and brought me in a new modem, and the problem stopped.
