Thanks.
I have tried with a different CAT6 cable.
My TV box has been factory reset 5 times, and every time I'm asked to do it I have to re setup everything and log into all my apps.
I'll call again tomorrow
Just to check the obvious…just in case.
You’re using the BT Hub right?
Yeah. The Smart Hub 2
After not receiving the replacement red cable, I escalated the issue.
My broadand connection was confirmed fine and that this could not be caused by the cable.
A replacement TV box was sent to me to rule out it being an issue with the box. Same issue with the replacement.
It has now been raised with a technical team and I am waiting a response.
Will update again once resolved
