We upgraded to 1Gig the other week, but it's never been quite reliable, going down a few times in the few weeks we've had it. Now we are only reaching top speeds of 400mbps when VM guarantees 552mpbs.
Here's the diag info, I wasn't able to run the SamKnows test from any of my devices, plugged directly into my Hub 5 or not.
