see what happened to me in my post recenntly re tuning the modem with a supplimentary device and checking all the connections.
I got that. I was just confused given the original post was about someone else's connection, not the original poster.
Delighted you're happy with the service you received though the 'tuning of the circuity/modem' was just an in-line attenuator. Nice and easy.
