CM400 Cable Modem
Can someone help me. My modem keeps losing internet connection. I purchased it in January, 2020 and it worked fine for 2 months. I've rebooted, reset, etc and it will not hold the internet connection....
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.
Do you have a wifi router connected to the CM modem? If so, what is the Mfr and model# of this router?
