Router won’t connect to verified internet connectio
I am trying to set up an RBR660 router. After connecting to the ISP modem, it keeps saying “no internet connection detected” even though 1) cables are all working properly (tested with other device); ...

What happens if you power OFF The RBR and RBS for 1 minute, then back on with the RBR first, then about 30 seconds later, power ON one RBS at a time. Does the RBS connect and show up in the WEB UI? Might bring the RBS to same room as RBR to check this...
Do they appear in Orbi app at all?If they don't, you might disconnect the RBR from the ISP service.
Change the RBR back to 192.168.1.1 and apply the change and let the system reboot. May need to power cycle the RBS as well here. Then give about 10 minutes, check the RBRs web page for RBS. They should appear in the WEB UI. If they do either change the RBR back to 192.168.4.1 or try 192.168.0.1. I've always used .0.1 and everything has worked on this submet.

It’s a Calix FTTH modem - it has two useable DHCP Ethernet ports. One is connected directly to the to a Windows laptop with no issues connecting to Internet (no Static IP or PPPoE, and the other port works perfectly with AirPort Express, when connected directly to a MAC Air, but when I use same cable to connect to ORBI Internet port, orbi app says cables are connected but no internet

It would really be helpful to know the exact model number of the Calix device.
Reason: Although some devices have more than one Ethernet port, they function correctly only when there is only one device connected at a time. I may not be reading the description correctly, but it appears to me that there are two devices connected to the Calix at the same time.
- RafK1Jan 19, 2025TutorThanks - it’s a Calix T073G-2. ISP tech support told me to use either LAN 2 or LAN 3 for connecting router or direct connection. With my previous setup, I connected the Airport Extreme to LAN 2, and a direct PC to LAN 3 without any issues. When I first tried to install and configure the ORBI, I only had it connected to the router on LAN 2, without any issues nothing else connected. Thanks again for helping me troubleshoot this. My next step will be to review the DNS setting in the AirPort Extreme, as well as assigned dynamic IPs, to see if there’s anything funky in the ISP setup (but based on previous experience, am 99% positive that they just provide a dynamic IP with no additional configuration)

Thanks for the product number. This is clearly a combination fiber ONT/router/WiFi/phone unit:

According to another User Manual I found on line, the Calix will have a LAN address of 192.168.1.1.
It will assign an IP address to every device connected to it in the 192.168.1.x subnet.
When this happens, the Orbi will switch to the IP subnet 10.0.0.1 for devices connected to it.
My next step would be to connect a computer to one of the Ethernet ports on the Orbi and open a web browser to 10.0.0.1
Ignore stupid warning messages about the connection being insecure.
This is a classic "Double NAT" situation, which can interfere with specific network applications. (Internet search for examples.) If one of this situations affects you, then there are several options for dealing with it.
