Upstream/Downstream
Hello,
Since I'd have to pay for support with Netgear CS I'm making this post.
My upstream & downstream LEDs blink all the time and not just the normal flicker.
I've power cycled many times and it stays solid for maybe a day and then they start again.
My network seems to be working pretty well and I've checked multiple times with my ISP and they say it's all good on their side.
Is there a way to fix this or is it just the way it is. There doesn't seem to be much support with this so far.
Thanks

Power levels are good.
However I see lots of Errors in the Event logs. Any Criticals, Errors or Warnings seen in the event logs needs to be reviewed and resolved by the ISP. Indicates a signal issue on the ISP line up to the modem.
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.
Start with removing any amplifiers, signal attenuators, or splitters from the coax.
From there check the line for kinks, damage, moisture in the line.
Check the connectors for improperly made ends, foil touching the copper coax line, loose connections, bad/old/cheap connectors, or corroded connections. Replace them if you do.
Be sure to power OFF the modem for 1 minute then back ON.

Is the model of the modem the CM1200?
Please post a copy and paste of the modems connection status and event log page.

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?Yes, it is a CM1200 modem.
I definitely have a high quality CAT6 or higher cable from the modem to the router.
The router is a TP Link AC4000 MU-MIMO Tri-Band Wifi Router.
It looks like I can only attach one screenshot at a time so I'll have to make a couple posts so you can see the connection status and the event logs.
Here is some event logs.
I can post more of the connection status or the event logs if needed.
It only lets me post one screenshot at a time.
Bits and pieces of the connection status or event logs are difficult to evaluate.
