You need to double filter Sky boxes, they cause horrendous amounts of noise on the line
i thought about it and may be being a dumb f**k but how can you double filter?
A microfilter plugs into the wall socket and splits the adsl and telephone so if you plug another filter into the first, it has to go into the tel socket due to its connection, then you will have no adsl comming out of the second filter just the first?
have i missed something?
just tried mine on speedtest.net with the sky box unplugged:
not impressed! think i need to contact sky as my broadband is with them!
With the box plugged in (single filter):
Nor me.
I might experiment though. The 'bell circuit' trick was a massive winner for me.
