Re: Gradually falling upstream power level
Sounds like a modem or cabling issue to me - Technical Support is on 0845 650 0925 for you, Clive - give them a ring! Alternatively, send me a PM with the MAC ID of the SACM (it's on the bottom, just under a barcode), and I'll have a look at it when I'm in work later today.
EDIT: An attenuator would be a little silver widget fitted on the back of the modem, protruding by about two inches where the co-axial cable screws in.
