Netgear CM600 No Internet
But tonight I think something has finally failed. I have power cycled the modem 3 times and it still says Cable Connection IN PROCESS when I login to 192.168.100.1
How do I nail down that it's the modem that failed or my connection from the street to the house ?
Thank you. I have uploaded a photo of the lights currently flashing on the modem

Re: Netgear CM600 No Internet
Do you have a screen snip of the cable connections page and the event logs from the modem?

Re: Netgear CM600 No Internet
Since I've made this thread it hasn't done it, until yesterday.
Here's the log:

Re: Netgear CM600 No Internet
Your event log is indicating a line issue. But you don't have the cable connections page attached. that lets us look at signal strengths and suggest things to try.
(next time get a screen snip . much easier to read)

Click on "choose file" and add them 1 as a time. When you insert a photo into the post, a moderator has to approve them and it can take a while

Re: Netgear CM600 No Internet
You've got errors in your line, your power levels are all over, and only 1 locked upstream.
Check your coax line for kinks, spliters, amplifiers, or signal attenuators. Remove them if you have them.
Check the line for old/bad/cheap/corroded/loose connections. Preferably, move the modem to right where the coax enters the home to prevent wiring in the home from being the issue. Then connect it and try it. if its still having issues, take the same screensnips and post them here. The isp might need to check the line in that case.

Re: Netgear CM600 No Internet
The connection from the pole to the house is exposed, that seems like it would effect the signal.
