Orbi RBR20 Router keeps dropping ethernet link to Cable modem every few hours. Once ethernet cable is un-plugged and plugged back in, the link recovers. Then again after a few hours link drops again.
Cable modem is ok, since other devices to it do not drop link.

Already updated firmware to latest, didn't help.
Any ideas what to try?
Can you tell us what brand cable modem and how your orbi and other devices are hooked up to it?
You say other devices connected to the cable modem do not have this problem? So is your Orbi RBR20 in bridge mode?
Cable modem is Netgear CG3000Dv2 - N450. It has 4 ethernet ports. One of them connected to Orbi RBR20, other 2 ports connected to couple of other devices. On the other devices, there is no link drop issue. I switched connected to Orbi to other ports as well, still does not work.
I dont use the wifi from Netgear Cable modem router because it is in master closet in one corner of the house. Orbi RBR20 is places in a more central place for all wifi access, with a satellite Orbi extending the range. I didn't set Orbi RBR20 in bridge mode, just whatever the factory default setting is.
Just disabling WIFI in your cable router will not disable its DHCP router functions. So you are probable running a double NAT. Try putting the Orbi in AP mode or disable DHCP in the cable router.
How to disable DHCP mode in router:
Launch a web browser from a computer or mobile device that is connected to your router’s network.
Enter the router user name and password. The user name isadmin. The default password ispassword. The user name and password are case-sensitive. The BASIC Home page displays.
SelectADVANCED > Setup > LAN Setup.
Clear theUse Router as DHCP Servercheck box.
Click theApplybutton.
(Optional) If this service is disabled and no other DHCP server is on your network, set your computer IP addresses manually so that they can access the router.
1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.
2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.
