Have the ISP check the signal and line quality UP to the modem. Be sure the ISP provisions the modem correctly.
Be sure there are no coax cable line splitters in the between the modem and ISP service box.
Be sure your using good quality RG6 coax cable up to the modem.
Be sure to power OFF the modem for 1 minute then back ON.

What happens if you uncheck the "Enable Extended Upstream Transmit Power"? Something I never had enabled on my CM1200.
do you have a splitter or signal attenuator you can add? your power levels are running hot.
Yeah I do but I just took it out because everyone kept telling me I shouldn't have any splitters. Just a straight cable from Spectrum's box on the outside of my house to my cable modem. So I took the splitter out.
