PS3 Can't connect to session with a single friend.

One of my band members who I have been playing with since Rock Band 2 came out all of a sudden last week we cannot connect to each other anymore. We are both NAT Type 2 and nothing changed with our routers. How come we could connect fine up until last week but now we cannot, this to me says something changed on your end Harmonix. Notes for patches might help this.

It may be a longshot but this started happening right after Daylight Savings changed the times.

I just wanted to follow this up and say I borrowed a router from a friend and tried it out and now we can connect to each other again. No idea why the AT&T 6800G would stop working all of a sudden and the older model Linksys would work fine. The only difference other than the model is the Linksys is non wireless (I was using the 6800G as wired too however) and this is the big one, UPnP is not supported on the Linksys. I have read of other PS3 games having problems when UPnP is enabled. Perhaps this can help Harmonix track down the problem.
