Help with Orbi RBR20 Connection to Spectrum Modem

Question

I just switched from google fiber to spectrum (use to be Time Warner Cable). My orbi mesh worked fine with Google fiber. I cannot get an internet connection with the new spectrum modem. When I follow directions, it pulses white, but never becomes a solid white.&nbsp; My phone sees the orbi, but I get back message "no internet".&nbsp; If I unplug the modem, the Orbi turns mangenta.&nbsp; I tried a backup Belkin router and it connects.&nbsp; I appreciate any thoughts on how to get my mesh up and running again.&nbsp; Thank you.

Please identify the brand and model of cable modem provided by Spectrum.

Is is correct to assume that both the Spectrum modem and Orbi were powered off. Modem powered on and allowed to stabilize. Then Orbi powered on?

With Google fiber, was the Orbi in "router" or "access point" mode?

Thanks

Thank you. Yes, I powered off both devices several times, waiting for modem first to start up, then Orbi. Orbi only ever pulsed white. When I first got Orbi, I did have problem with NAT, as the google box was both modem and router. I don’t remember how i fixed it. But i have a “fix”... i plugged the Orbi into the Belkin router and the system works! Not it’s a work around. I appreciate your thoughts

Whats the Mfr and model# of the device between the modem and Orbi RBR router? Seems like this router that can be removed and the RBR put in it's place.&nbsp;Power OFF the ISP modem and RBR for 30 seconds, then power back on the ISP modem and let it sync then power ON the RBR while the RBR is connected directly to the modem.&nbsp;marty1959&nbsp;wrote:Thank you.
