In an old property, the BT cable ran through the loft space, and I was going to re-terminate in the loft, and install a router there, with obvious benefits in WiFi signal (theoretically!). However, since even the BT modems come with an ethernet port between modem/router, I'd put the cable length in there, since I've not heard of any problems with ~50m ethernet. Of course if you're wiring up an industrial unit, there's the option of fibre becoming more cost-effective, but I doubt you're really that desperate on standard UK VDSL ;). MJE
