From what we saw at the Hawaii Regional, it's apparent that D-Link firmware 1.4 is a factor. Every match that had obvious multiple-robot control lag included a robot bearing that revision. It's not completely clear, since not every match with a 1.4-bearing robot had a problem. But we have something to work with, and we can try to prevent it from happening again by downgrading to revision 1.21 when necessary.

Alan,
the only puzzling part here, is that even after switching to the 1.21 as you noted BEFORE eliminations, the problem still existed for teams AND in matches that we werent even in.
The only permanent positive note is that it didnt happen to our team again.

I can only conclude that something much bigger is happening, and not just at our regional as noted in this thread.
