Here we go again,
Friday morning I got up tried to go online. Nothing happened. There's a blue light on HUB but no browser will connect. Getting timeout messages and server stopped responding messages. Speed test app won't run and says 'latency error'.
We've got a phone line and can make calls.
If I slave any of my tec to a mobile phone wireless hotspot then everything works fine so I don't think its a problem with my Ipad, Ipod or netbook.
Rang BT and they reset the line. This has made no difference.
Reset the HUB - hard reset and reboot and the blue light is on but still getting the same problem.
There is a fault logged.
Also used a wired and wireless connnection
Cannot think of anything else. It may be a new fault that does not show on the status page yet.
See if your exchange code shows up on this page https://status.zen.co.uk/broadband/
This tends to give more info that the BT one.
There is planned maintenance listed for my dialing code area for 2/12!
Perhaps it a faulty card, and that is when they intend to replace it?
Often these are done as a planned work, if its going to affect a lot of customers.
Does it mention that its a fibre cabinet issue?
I'm afraid that this won't help you, but I have a similar problem - my Home Hub 6 seems to be seriously flakey: it'll have blue lights, everything is apparently connected fine etc. and yet several times a day, I'll lose connectivity for a variable amount of time. Rebooting the hub sometimes "fixes" it, sometimes doesn't.
I also use 4G on my mobile to get myself out of a tight spot, and like you, everything works perfectly when I do so.
Based on my experience, the HomeHub6 is much worse for this than the HomeHub5 - and that wasn't great! 😞
