Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.
What is the brand and model of the host wifi router connected to the modem?
I'm using a Firewalla. Please note that the new Modem works perfectly and is the same exact model. CM2000.
I tried all of the troubleshooting steps prior to contacting Comcast, including replacing all cables except the power adapter (naturally).
The Firmware was only upgradable through the ISP per the instructions when I logged into the Modem.
So would need to have the initial CM modem online so you can collect the logs asked for to see if there are any items that stand out.
Try the 1st CM modem at a different location to see if the problem follows.
If the 2nd CM modem is working. Possible the 1st one is could faulty. Nothing we can do about that here in the forums. Something to contact NG support about.
