RBR750 dropping internet after 10 mins of every reboot

[lipstick]

I am forced to use Comcast Xfi Modem to avoid paying extra for unlimited data.

But I have Wifi turned off on the comcast modem and instead I am using 3 Orbi's in AP mode.

The setup has been working smoothly since several months. However since today morning my Orbi keeps on dropping internet and turning purple. Then I unplug and replug the Orbi router and it works perfectly for ~10 mins only to drop internet again.

Things I have done so far:

1. Made sure that I am on the latest firmware: 4.6.14.3
2. Factory Reset the Orbi

Any idea how can I fix it?

Has a power off for 1 minute then back ON with the ISP modem and router been performed since last update?
Be sure to restart your network in this sequence:
Turn off and unplug modem.
Turn off router and computers.
Plug in and turn on modem. Wait 2 minutes for it to connect.
Turn on the router and wait 2 minutes for it to connect.
Turn on computers and rest of network.

Check the ISP modem if the RBR is turning PINK while in AP mode:

What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?
Be sure your using a good quality LAN cable between the modem and router. CAT6 is recommended.

thank you for your reply.

yes, i did restart my xfinity gateway modem and made sure it's working before connecting my orbi router.

my ISP modem's internet connection is stable while RBR750 is purple. so the issue is definitely with my Orbi.

i do have CAT 6 connected between modem and orbi.

this is the modem: XFI ADVANCED GATEWAY (XB7)

Be sure the ISP Modem is giving the RBR services and a IP address. One reason for the PINK led is that the RBR isn't getting anything from the ISP Modem. Setup a IP address reservation for the RBR in AP mode. 

Are you using Dynamic or Static IP address configuration for the RBR in AP mode? 

Might try the RBR in router mode and use the modems DMZ for the RBR. 

Try a factory reset and setup from scratch.

Hello lipstick,

Welcome to the NETGEAR Community!

I understand that you are having interim disconnects with your RBR750. Please try changing your Comcast Xfi modem to bridge mode then change your RBR750 to router mode. 

Please keep us informed of the progress of this issue!!

Best,

but Orbi should still work in AP mode right? why is it needed for me to use my xfinity gateway in bridge mode? i want my continue to use my xfinity gateway as a router.

Orbi still works for like 10 mins so it is getting the right IP address.

Might try the RBR in router mode and use the modems DMZ for the RBR while both are in router mode to see if the problem continues.

Looks like I may have found a bug.

So my router is in AP mode connected via wireless mesh to Satellite1 and connected via Ethernet to Satellite2.

When I remove Satellite2 from direct Ethernet connection, internet is stable. However when I don't then the LED light on the main router keeps turning magenta after every 10 mins.

Need to test it out for a few more days to confirm but so far its looking promising.

Can someone please log this bug with the engineering team?

What happens if you ethernet connect SAT1 to the RBR and leave SAT2 turned OFF or wirelessly connected? 

What CAT# cable is being used in between SAT1 and SAT2? 

Direct connection between them or is there a LAN switch? 

Possible bug this configuration you have. You may need to capture RBR and RBS debug logs for review. Please respond to Kevin's post and send him your information.

When I had my 7 series online, I only have 1 RBS and it was working via ethernet connected to the RBR.
