What happens to me is when I'm racing, people will join or leave the lobby. Then the cars that I'm racing with, all of a sudden, act like no one is controlling them. Then one by one they'll disappear, then I'm all alone. If I exit out, and wait for the race to get done. I won't be able to connect with the other racers, in the lobby. I would have to exit and rejoin. It doesn't happen all the time, but maybe 30-35% of the time. Already cleared the cache, and I'll clear it again later. Might have to look at the router again, but I don't have any problems with other PS3 games, or Xbox live.
