I have had VF box for about 3 months, now, and it continually reboots. It used to last up to an hour, but today its just every 5 minutes or so. Basically makes TV unusable.
When we signed up the first box we got did the same thing, so we asked for a replacement and it made no difference.
We have 200meg/s coming though, so its fast enough. Our Netflix Roku works perfectly fine and never reboots. We unplugged it and it made no difference to the VBox. Our old TBox was totally stable.
We have the fancy VF One Hub thing that has worked perfectly with the TBox, and never drops out. I have swapped Lan points around.
It just seems pointless ringing VF again and not having an answer, the last time they didn't know what it was either so just gave us another one..
