I also had your issue with BT and WiFi, they basically told me everything has to be wired in and they only support 4 things connected via ethernet... Anyway,
Assuming a Sky Q Hub.
Head over here:
Is your modem status not showing as connected? Any line stats below?
Here is mine:
Line Rate - Upstream (Kbps):9995
Line Rate - Downstream (Kbps):39998
Scroll to the bottom and click show statistics. Do yours all show as 0 ie not connected?
Here's mine for reference:
Broadband Link Downstream Upstream
Connection Speed 39998 kbps 9995 kbps
Line Attenuation 13.2 dB 0.0 dB
Noise Margin 10.3 dB 12.12 dB
Sounds silly have you changed filters and if using a prefiltered socket, tried the test socket with a filter?
