Hello Virgin.
I am struggling with the same problem, i.e. a red light on hub3.
I don't remember when it appeared, but when I noticed it, I didn't pay much
attention to it because I didn't have any connection problems.
But when I noticed the colour again, I searched the internet and found out that
it is usually related to the router overheating. So I tried all the possible
solutions to this problem that are also on this forum. I disconnected the power
cable overnight and performed a pinhole reset without success.
Finally, I used the hub's 3 network diagnostic tool.
The results showed that everything was fine. Here is the content of the report:
Your home network has a few problems.
Checking Broadband Service v
Checking Telephone Service x
Checking Ethernet Connections v
Checking WiFi Connections v
If you still think something is wrong, please check the following
1 Gateway IPv4 address is valid.
2 Your broadband connection is working.
3 Your broadband connection is ready.
4 The temperature of your Hub 3.0 is normal.
5 The status of telephone line 1 is not ready.
6 The status of telephone line 2 is not ready.
I also checked whether there were any problems with the internet connection in
my area, and it turned out that there was an issue, but the repair is almost complete
and broadband should be working. But even if there was a problem in my area,
I didn't notice any connection issues.
So the only problem, or perhaps not, is the colour of indicator on hub3.
So how can you help me?
