Re: Entry socket point set up and extension query

Hi, we can no longer connect an extension cable into the wall entry socket because the thick coaxial cable has been run straight from it and around the front room to the hall and into the back of the hub. An extension cable can now only be connected to the coax termination in the hall. Is this correct please or should the narrower extension cable have been connected at the entry point and used to run around the front room instead of the coax?

There is also a small black wire hanging down out of the bottom of the new wall socket and we wondered what this was and if this was normal/safe?

Lastly, the engineer kindly left an extension cable to connect to the end of the coax in the hall should we want to place the hub on a taller table. However the cable he left does not have the thicker bit in it to protect against current surge, unlike the cable which was sent originally together with the hub. Should we use the cable he left or the one with the thicker bit for surge protection please?
