I have been having this problem for a long time but it hasn't been much of an issue because I am not home most of the day. However, I am now home for most of the day and this is a big problem. I upgraded all my equipment within the last year. new modem and router. i know it is not my computer be abuse other devices connected to the router will stop working at the same time, i have tried 3 different routers and 2 different modems.
I had a technician come out last August and he basically reset things and checked connections. It didn't happen while he was here so he couldn't diagnose the problem. I still had to pay for the visit.
The problem: chronic, short-term (2-10 minute) loss of internet service. Lights on my netgear cm700 will go from solid to blinking, mainly the downstream light followed by the internet light.
What could be causing this problem and how do I resolve it?
Sounds like a problem with the downstream signal. Can you post your signal levels from 192.168.100.1? See here for Netgear instructions.
Thanks for providing the link on the how to. I took a screenshot and attached it below. My up and down signals seem to be within the correct range. However, I am seeing a high percentage of uncorrectables. Is that a problem?
I think what is causing the problem is your downstream SNR for some of your channels are weaker then the others, so the modem is rebooting to re-scan sometimes. How often does it happen?
As for how to troubleshoot it, did you want to discuss the coaxial layout inside your house or have you isolated all of that already? Do you know what your levels are as they enter the house?
It is sporadic.Sometimes only a couple times in a day. Sometimes 10 or more times. Yesterday, it happened 10+ times in a 2 hour period. I know this because I was trying to watch a movie via streaming service.
I live in an apartment building. I only have 1 connection into my apartment and I am not splitting it anywhere. I only use the modem. No cable tv service. How would I go about checking the levels entering my apartment? I would have assumed the technician did that last time I had them come out.

Is there a maintenance area or wire closet somewhere in the apartment complex? Do you know if the technician went in there last time he was out? If not, I would suggest have them check there as that is usually where the problem is in apartments. It could be as simple as asking for the door to be left unlocked for the Cox technician.

I would think so too, but they must have missed something if the problem is still occurring. I think the problem has something to do with you sharing your signal with other in your apartment complex, but that is difficult to diagnose without access to all areas.
