Power on the down channels are within spec.
Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.

Be sure your using good quality RG6 coax cable up to the modem.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
