I think VM may have pushed an update to the Hub's. I have the Gig1 router and noticed that my internet dropped out at around 2am, when I checked the router it was flashing green and since I run the router in bridged mode, it now stays solid green?
As for the packet loss issues, I myself had this problem and it took me days to figure out since VM support team wasn't helpful, try resetting the router by pushing the pin hole reset for EXACTLY 1 minute. After 1 minute release and then let the router do its thing and try doing some tests again.
