Since the PSN came on, I decided to spend some time online.

The matches will start out fine (completely lag-free), but after about 5 minutes in I'll start getting a slide-show style
lag fest of rubber banding until I get disconnected. I'll look at my team's connection, and they'll all have green connections
whereas my own is only suddenly red.

I thought it might have to do with my PS3 getting stuck in NAT-3 and being unable to get
to NAT-2 despite trying DMZ, port range forwarding, port triggering, and QoS adjustments.
However, I've never had a problem with online multiplayer short of the original Little Big Planet at times.

I just wondered if anyone else was experiencing this issue. I wondered if it might be PSN
restoration related (unlikely), or if it's just me (more likely).

Yes, been experiencing the same issues as you hope they fix

Glad it's not just me =( svcks though.

Yeah I'm having the same problem rubberbanding.
Game is unplayable online right now ,hope they fix this .

PS3 patch seems to have fixed it for me. ^^b

I just played through the entire Resistance campaign online with a few randoms and didn't have any lag issues the whole day! #feelinglucky

We're having the same problem on the 360 too.

But the 360 also got the update - are you still expereicning some lag problems even with the update ?
