F1 2011 XBox multiplayer problems?

[smartey01]

Hi all,

Last night me and friends set up a private match 20% with quali a handful of AI, all was working fine and smooth until bam, 3 laps of quali and it looses connection to two of us. We then get invited back in to sit out the rest of quali and start the race fine. Few laps in again, bam lost connection again?

Has anyone come across anything similar?

Any ideas to what causes this?

Im ruling out my internet connection as I joined a 50% race after with a random and completed it fine & never occured this error before.

Cheers...
