Any sparkies / phone engineers here?
Should my BT master socket be wired directly to the thick black cable that comes in from the road? 'cos mine is wired to the thinner white cable which runs up three floors higher where it joins the thicker cable in a junction box in the loft.
I reckon this is exposing my broadband to interference and reducing its speed. It's come to my notice as I get about 8meg whereas very close neighbours get 13 - 14meg.
Advice appreciated (and sorry this isn't a strictly wi fi question!)
