Doh - filter - what filter
Just moved from cable to Sky Broadband (to get Sky+ box/Sky Sports) and needed to put a telephone extension in main server room (wife calls it the spare bedroom :) ) as that's where all my cables go to.
When I re-plugged in the Sky router I noticed I was only geting 1.7MBs instead of the 6.7MBs I'd got when it was plugged into the master socket in the living room.
Since I finished off the extension wiring in the dark - I thought I must have done something nasty to the cable :(
It was only when someone rang us this morning and I couldn't hear them properly due to some interference on the line did the light go on - I'd forgotten to put a microfilter in the circuit back in the living room :( :( :(
PS And to think that people pay me to come to their house and sort out their broadband problems :)
