Your upstream power is way to high. It'd definitely cause issues.

Any splitters, amplifiers, or signal attenuators inline? If so, remove them. check the line all the way back to the box. They've been known to stick signal attenuators in the box.

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 them back ON.

Has a factory reset been performed on the modem?

Yes, I have performed factory reset but its not working either&nbsp;

IF all the other suggestions have been checked, you could try a different modem to see if the problem remains for goes away. If it goes away with a new modem, then the C series modem could be marked as the culprit, if the problem continues with a new modem then there is a ISP service line issue that the ISP needs to resolve.&nbsp;
