Connected, Online, but ALL Devices Offline? CBK752/CBR750 Cable Modem w/ Spectrum
Hi all, I’ve been back and forth with Netgear CS and Spectrum for the last couple weeks to figure out why the Orbi WiFi 6 model CBR750 (CBK752-100NAS) I purchased to replace the Spectrum provid...

Hello again,
Sorry about the delayed response but oddly enough so far there haven't been any bizarre outages since a couple days after the direct power and internet/phone line were reconfigured and cable modem reprovisioned by Spectrum! The last change I made per Netgear CS's recommendation was changing the MTU size to 1475 on 10/16 which was the first MTU size they changed it to when I still had random unexplainable outages. I have not yet moved the satellite and cable modem further than the ~20 feet yet but will today just for better performance in general.
DNS is still currently on 1.1.1.1/1.0.0.1, 2.4GHz on channel 11, and 5GHz on channel 44, which have been there since my first or second call with Netgear CS. Regarding WiFi Neighbors, how would I go about checking their channels? Do you mean my literal neighbors' WiFi or just devices within my network?
For vkdelta I have the Event Logs and Logs attached. For Event Logs, we stopped experiencing any problems beginning on the 17th/18th of October, and before that it only shows a number of "CM-STATUS message sent. Event Type Code: 5" for October 16th. For the Logs, whenever the "online-but-offline" outages occurred they only showed the DHCP lines shown, nothing out of the ordinary.
Thank you both in advance!

Logs attached as I could not attach more than one image to my initial post.
Thanks in advance!

can you please press "clear log" on the DOCSIS event log page and monitor for 24 hours and re-post the logs.
which ISP are you on?
there are LOT of T3 timeouts which is causing WAN to disconnect.
