CM1200 Modem Problems

Please can someone help me with why my new modem would be doing this to my channels? Im running through Mediacom for the ISP. They dont have any info about this since its customer owned modem. If there are any experts or anyone has true insight here please and thanks for answering!

Re: CM1200 Modem Problems

Disable LAG on the modem.

Have the ISP check the signal and line quality UP to the modem. 
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.
