About 3 times a week, my CBR40 will stop passing traffic and becomes unresponsive to all devices (wired & wireless). Sometimes I can reboot the router/modem from the Orbi iOS app, other times I can reboot via the web admin page. Sometimes neither work and I will manauly reboot the router. The issue occurs at various times of day. No pattern that I can notice. Middle of the night, midle of the day. It cant possibly be related to oversubscription - I have less than 20 devices and most of them a low-bandwith IOT devices like smart plugs and lights. Im not puhing the router very hard at all. I'm about to put the CBR40 router on a smart plug/timer and schdeule a reboot every morning at 2AM. This is a brand-new product from a company with decades of network experience - I shouldnt have to be "engineering" my own ad-hoc workarounds and hacks to keep my household up and running. This issue - combined with the 5+ others I have menetioned in these forums - are almost enough to make me send it back for a refund and try out Eero (or go back to my previous Google Wi-fi mesh system). What's up NETGEAR?

What FW version are you using on the CBK40 system? Is the CBR40 associated with your ISP as a CBR40 or CM700? Do you have access to the router/modems web page when this happens? You might enable debug logging found under 192.168.1.1\debug.htm. Also check your Admin/Logs for router and modem info and post the next time this happens. Might have your ISP confirm the signal levels seen in the logs are to spec on there system. Ask them to check there logs to see if they detected any disconnects during the time frames your experiencing this. I did experience my first CBR40 hand the night before last. Had been playing xbox on two consoles, same game, game had ended and I was checking out FB on my iphone and could not get FB to load anything. Tried a different app and same thing. We still had some form of connection. I wanted to reboot the CBR40 before roomie got back from break so I used the Orbi app and rebooted there. I did see a notice on the app that said the Orbi wasn't connected to the internet. So something had happened. The app was able to connect and I did the reboot from there. This is the first experience of this. It's been solid since setting up the modem. I did look at the logs and I believe there was a "No Ranging" message seen around the time frame my CBR40 stopped. Could be a ISP issue for me. CBR has been good since the reboot. DarrenM

Please PM me with your debug logs.

pls check the DOCSIS connection table and DOCSIS Event logs. If the power levels are bad and have lot of correctables, or too many T3 timeouts, that would be lead to issues.

The last 24 hours have been smooth sailing for me. Here's a break-down of the changes made in my home environment in the last day: - A Spectrum technician resolved some physical cabling issues at my coaxial 'home run' from the Spectrum demarkcation to my Orbi CBR40. DB Signals were adjust by Spectrum and cable was re-terminated etc. This is a brand-new home and apparently there were some issues with the way the coaxial cable was ran in my walls, which caused some bending/twisiitng and caused microreflections. - Spectrum was notified that my modem is a CBR40 (i.e.; changed from a NETGEAR CM700 before the CBR40 "officailly" supported). Not sure what was changed on the back-end to accomodate this change. For the last few weeks the CBR40 was not on Spectrum's "approved" list. -Firmware 2.1.4.6_1.0.8 was downloaded and installed on my CBR40. This is the first firmware patch for the CBR40. I did lots of testing... I did a lot of testing with streaming 1080P and 4K content, played various online multi-player games on (2) Xbox One consoles (Far Cry 5, Ghost Recon Wildlands, GTA5, Assassian's Creed) Configured and controlled a bunch of HomeKit IOT devices. Lights, plugs, cameras etc. Pushed various types of content to (2) AppleTVs over AirPlay (mDNS, Bonjour, etc) Downloaded and installed faily large macOS patches to desktops and laptops. Various speed tests from wired and wireless devices. (typically I could force my router to stall, reboot etc if I pushed hard enough (or waited long enough). So far it has been rock solid!

What FW version are you using on the CBK40 system? The firmware is the one and only firmware version. The CBK40 mesh system only been on the retail market for a few weeks. No new updates have been available to my knowledge. Just checked again - "No new updates are available" Is the CBR40 associated with your ISP as a CBR40 or CM700? I registered the CBR40 modem/router with my ISP (Spectrum KC MO USA) as a CM700 because Spectrum didnt know what a CBR40 was (it wasnt in their list of "supported modems" at the time of my purchase. This surpised me because NETGEAR claimed that Spectum was an "offical" ISP partner. Do you have access to the router/modems web page when this happens? Yes, at times I can get to the logs - just depends on when the isue occurs, I also have (2) Xbox One consoles in my home. I have been play Far Cry 5 on both systems via Xbox Live (coop)

Might try setting manual channels on the router, maybe 11 on 2.4ghz. 36 on 5Ghz.

Disable MIMO on the router as well. I have Beamforming enabled and seems to be working well for me.

I would enable debug logging under the debug.htm UI let it start capturing logs.

May need to contact one of the forum moderators about this if this continues.
