I having the same issues with Spectrum.

I’m using the RBR50, and most of the time the Orbi loses connection to the CM1200, and I’ll need to reset both. This happens 10-20 times a day, but Orbi’s logs say it’s still “up”.

And yes, I’ve tried the factory reset, the channels, all the stuff they recommend immediately in this forum. I have the 2.5.0.40 firmware on the Orbi and all satellites.

  We are replacing all equipment with Ubiquiti UniFi Dream Machine and BeaconHD’s. Just tested for 10 days and it’s been solid.
  
  No Netgear response and this equipment is just total junk without solid reliable firmware. I hope everyone sees this that is considering buying Netgear Orbi.

  If you connect a wired PC to the CM1200 modem do you still see these issues with just the PC connected? Been some posts over on the cable modem forum with the 1200 having some issues. I have a CM1100 and my RBK50 v40 is connected to WAN port #1 on the CM1100 modem. Not seeing any issues with this modem. I have the 1200 however havn't had time to put it online yet. CM1100 run my RBK852 on WAN port #2.
  
  Ensure your ISP check the signal and line quality up to the modem.
  Be sure there are no coax cable line splitters in between the ISP service box and modem.

Can you configure the ISP modem for router mode, disable ALL wifi radios on the modem and then configure AP mode on the RBR50 and see if you still experience problems?

  That *is* the current configuration.
  
  The CM1200 does not have WiFi antennas. It’s a cable modem not a router.
  
  So it’s already “bridged” by nature of the device. And the Orbi is being used as the router. Setting the Orbi as access point mode wouldn’t work as the modem CM1200 is not a router.

    My bad. I forgot about that. Sorry about that. :smileyembarrassed:

    You can try this, update to v34 or v40 by manually downloading the FW files for the 50 series RBS and RBR. Manually update using a wired PC. After the RBS and RBR is updated, factory reset the RBR and setup from scratch. I would power OFF the CM modem for 30 seconds then back ON. Then walk thru the setup wizard with the RBR and complete the setup.
    
    See if this stops the internet drop and renews the IP address from the modem.
