PSU getting disconnected every 15 minutes

[Shazbot]

Basically, I'm allowed to play in 10-15 minute increments during the day. Then I get error 51 and have to log back in for another 10 minutes of trying to kill as many enemies as possible. If it's really late at night, though, I don't get disconnected and can play my brains out--but only being able to play normally from 1:00a.m on sucks balls. It's been like this since starting online last week.

I'd feel a lot better if this is a common problem everywhere until the next server update. But I somehow don't get the feeling that most everybody else is also playing the game 10 minutes at a time...

It sounds like an Internet Service Provider or router issue. Do you experience this problem with other games or instant messaging programs?

Hmmmm...definately seems to be a modem problem b/c I switched with my neighbor and the disconnections stopped. Then my neighbor complained of getting disconnected while using my modem. Pickles.
