[QUOTE="ProDave, post: 392727, member: 6969"] Okay I've done some digging around. The standard quoted resistance is 0.188 :ohms per metre. So my measured 13.9 :ohms makes my actual cable length only 74 metres. A lot less than I paced it out at (I have short legs) and a 100M drum would have been enough You keep telling me I ballsed it up. BUT I specifically bought copper, screened, outdoor cable, not the cheap £20 copper covered ali carp from the well known corner shop. If it really is only 74 metres then it should have worked properly? which brings it back to the original question is a BT home hub carp at driving long cables, and would merely inserting a network switch at the source improve it?
