Cm2050v disconnects from isp

Lexxfyre · ‎2022-10-10

My modem seems to be dropping the isp overnight. Has been happening every other night for about a week. I didn’t see any firmware updates. And all the cables attached are brand new. The router I have connected is a Firewalla.

Be sure your using a good quality LAN cable between the modem and router. CAT6 or CAT6A STP is recommended.

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.

Power looks ok but some channels are not the same as the others.
You have lots of criticals that the ISP needs to review and resolve.

So action is needed from the ISP to resolve? Is there anything I should mention to them specifically to get help with this issue?

FURRYe38 · ‎2022-10-20

Other than what I first posted about, they'll need to take a look and figure out the criticals.
