I have this problem. I have a terrible time with Virgin who say there is nothing wrong!!!!!. When they do an auto system check on phone the Hub reboots so there must be a problem. They sent an engineer who replaced the Hub telling me it was a fault with the hub. The new hub is still flashing !!!, still virgin say there is nothing wrong.
Comes to something when they don't know there own product.
On the basis of 'How often do I use it anyway?' I have turned off the WPS function and that has removed the flashing light. Not the answer I was hoping for and Virgin really should put more effort into solving the problem but at least the annoying flashing light has now gone.
Details of how to access the settings page are on a sticker on the bottom of the your Hub3
My Hub 3 just started doing this today. It doesn't seem to be causing any problems but it's always worrying when something occurs out-of-the-blue like this. I don't know what a WPS button is but I'll have a look later when I get back home and see if it fixes things.
My Hub 3.0 started doing this a few days ago. I've tried turning off and on again but it continues. I've also tried the WPS button fix but although it goes off it comes back on again after a short while. Router diagnostics show a red triangle next to WiFi but it all seems to be working fine. Hub status overview shows Internet online but next to Wireless it says "On (2.4 and 5 GHz), WPS in progress)".
So again it looks as if it has something to do with the WPS but why has it suddenly started to do this. All Ethernet and WiFi connections are working as normal. Router info shows:
Is that the latest firmware version? Driving me nuts!
