There was an upgrade a few days ago and a lot of people who had no problems before the upgrade have now got drop outs. My drop out was so severe I blew the hub switching it off and on every ten minutes. Got a new one coming and VM agent told me that the upgrade had corrupted my hub and that it was just a minority that would have this problem.
Maybe you're a minority too
My top blue light was steady and flashed when data was transmitting until the upgrade then it flashed continually. middle light was green and wireless was continuous blue. When it blew all turned continuous blue.
Regards.
