Thanks both. The white cable from the box goes into the wall, the black cable is separate and comes out of the same hole in the wall. I’ve unscrewed two additional connectors that have been added to it (see photos). I’ll buy the suggested connector from b&q and see if that manages to join it all up. Fingers crossed! Appreciate your help.


The only concern I have is you could be missing the isolator. The below looks VERY similar to the adapter attached to the wall:

The black cable would normally plug into the top of this, and the HUB cable to the bottom.
Also the mystery of the coax adapter could be the cable being re-used by sky for their services? Hopefully not.
