Thanks EGTE - 'splitter' it is then. Anyway, having 'restored' my setup (for MB from master(test) socket) to splitter, I have retained my 5'ish+ at the router/3'ish at the 'puter but I have started to get a few line errors again which I think points to a cheap E-Bay splitter
New router winging its way here for the weekend I hope so more testing to do.
MB: Down Attenuation 48Db, Noise margin 6Db, line length 4600m, and LLU has definitely improved both up and down. Gone from 3.6/700 at Router to 5.5/1.1
Don't get too excited about Infinity - looking at your attenuation I guess you are 'long line'? 1500m is the max for the fabled 'superfast' (24Mb) and at 5km + you may see a dead donkey. Old technology, anachronistic - and a waste of the BDUK money, as BT emerge (surprise surprise) as the probable only 'bidders' for the dosh
