A lot of this info was already in my post but i'll post it again.. No there is no color on the orbi. Status lights show up.
The firmware is current, there are no updates available.

Techs have checked the line and it says fine both inside and at the street level box.
Yes there is a splitter, the line splits between my cable box and my modem router.

The line and the splitter are brand new as of today.
The modem has been powered on/off many many times and cycled many many times.

I cannot paste the log currently. It does this sometimes where the log appears blank and will show up later. The errors in my original post are the same errors that show up around the downtime.

Please copy and paste the event log into a word doc then save off as a PDF then use the Choose File button on your next post to attach it.

Who is your ISP?

I see power levels are all over the place and mostly on the low side thought with in spec, channel 32 is -9db and is just too low:

https://kb.netgear.com/24311/Power-level-guidelines-for-a-NETGEAR-cable-modem-router

I recommend removing the splitter temporarily to see if the power comes up and the Correctables and Un-Correctables can get to all zeros.

I can't even view the event log. Its blank, eventually it updates, but sometimes it takes awhile. I dunno *shrug*

ISP is cox. The problem with removing the splitter is it removes the ability to access the cable tv, we only have the 1 cable for both internet and tv. I will give that a try later tonight though once the children are in bed and won't be upset about TV being gone.

  Is the FW version v.4 on the CBR?
  How was the FW updated on the CBR? Via Orbi app or CBRs web page using a wired PC and web browser?
  
  Is Armor, SPC or Traffic Meter enabled on the CBR?
  
  Has a factory reset and setup from scratch been performed since last FW update? A complete pull of the power adapters for a period of time after the factory reset then walk thru the setup wizard and setup from scratch. Recommend setting the default DHCP IP address pool range to the following after applying and a factory reset: 192.168.#.100 to 192.168.#.200.
  Factory reset the Orbi router and power it off for one minute. Then power ON the Orbi router and walk thru the setup wizard again using a wired PC and a web browser.
  Press the back reset button for 15 seconds then release.

    Firmware is V4.6.14.4_2.3.12
    
    I'll look into doing a factory reset. If not, the tech will be back tomorrow late afternoon to try with an ISP router to see if we can duplicate it with ISP provided.
