A mate of mine had been having problems ever since he got his\nbroadband. The ISP send out a new router and his sync was 1700kbps\nbefore hand and when he tried with the new router it increase t 3mbps.\nSo slight issue with the router but based upon his 500m distance from\nexchange and the fact the the line is actaully 900m long his isp (sky)\nsay the line should hand 17mbps. Its not even reaching 8mbps. Anyway,\nso i tired it at the test socket, as the router had been restarted\nmany times at an extension socket, and got 4.6- 4.9mbps sync. My first\ninstinct was the internal wiring is faulty and rip out the lot and\nreplace it with cat5. But when i put the faceplate back on and tested\nit at the same extension it was at the same speed as the test socket.\nPlugging it in the master socket, so on the faceplate however gives a\nrate of 1.6mbps.\nI thought they may have used alarm cable and a Capacitance issue might\nbe the problem, it may well cause this sort of problem.However he\ncable looks like twisted pair telephone cable. Only difference that I\nknow is that alarm cable normally has 3 pairs and the insulators of\nthe pairs are solid.\nCan see any obvious sources of EMI, no CFL lighting. The house is\nplagued with spot lights though , i am not sure if the give of\ninterference, otherwise the transformers I don't believe are close by\nto the telephone cable.\nAny Ideas on what could be the problem. I have ordered a filtered\nfaceplate anyway(XTE-2005) so that I can run a cat5 length to the\ndedicated extension for ADSL but any other ideas.
