For what it's worth I recorded a quick vid to show exactly what I mean. Every few minutes or so the white light just goes off for a few seconds and then comes back on. To me this is unusual, I've had the Superhub 5 for around 6 months now and it hasn't done this before. There was a service outage for nearly 2 days just last week and I'm wondering whether that has anything to do with it. It's not dropping the internet connection, or at least not that I notice and I'm working online nearly all day every day, but I have noticed that a few of my Wi-Fi devices are dropping off the network quite a lot which again is very unusual.
Flashing white light on the Hub5 usually means it is rebooting - thats not normal - look in the Hub settings -> network logs... and see what it is reporting.
