Can the drop in speed / connectivity between a master and extension socket really be as dramatic as SKY have informed me? They say they cannot do anything with an extension socket and have had to keep lowering the speed, capping it at 1.3meg etc just so the line would hold.
It got to the stage where everytime the PC had been off for a while the connection would drop (amber light or no light on router) and I had to make a phonecall..any phonecall, then the connection would start again about a minute into it.
I'm 4k from the exchange and my line can apparently support 2meg.
