A few problems with CM400

[googlypoo]

Hi,

I have had two problems that I believe are sourced to my NetGear modem.

1) Every 90 seconds (exactly!) when playing online games, my network drops for 4 seconds. I am on an ethernet connection directly to the router, which is connected to my CM400 via ethernet as well.

2) My modem loses connectivity altogether at some points. I know the problem is not the router because none of the lights appear to change status.

I contacted my ISP yesterday and they confirmed there is no problem on their end.

Does anyone know what could cause these issues?

EDIT: I should add I am using a TPLink AC1200 and there is no perceived change in status during the intermittent disconnects.

Hello googlypoo

Can you post the logs and the power levels of the modem? you can access the modem by going to 192.168.0.1 and use admin/password to log in.

I'm having similar issues with my CM400 using Comcast XFinity. I'm on firmware version V1.01.18 and when I try to access the event logs, I only get a picture of a frowny face. When I lose connection, I'm also unable to access the modem at 192.168.100.1

Have you tried a different web browser?

Same problem here.

CM400 is working well and suddenly I lose internet. It happens usually around midnight in my case.

When I check the modem after losing internet, all the lights are green. But a few minutes after that it starts blinking from downstream light again.

Usually I pull out the power and plug it back again and that fixes.

My router is fine and I can access it internally, but there is no access to 192.168.100.1.

Browser is not an issue, I have a yellow triangle on interet access icon of windows taskbar.

Somehow I cannot access modem log page. It gives just rotating icon forever.

My firmware version is V1.01.18.

Update: My Upstream Bonded Channels power levels are at 51.0 dBmV for all 4 channels and there is no lock on channel 4. Could this be the source of the issue?

Hello Wyrm

Yea it could be you may want to have your ISP check your levels they can typically do this with a remote tool they have.
