Orbi 960 not obtaing a DHCP address from upstream carrier 5G modem/router.
I'm having issues with an ORBI 960.
Details of the ORBI router are;
Hardware Version RBRE960
Firmware Version V7.2.7.15_5.1.16
GUI Language Version V3.0.3.12_2.1.30.3
Protection Engine Version 2.2.214.4/1.0.0.2049
Operation Mode Router
The Orbi system has been working without issue for the last 2 ½ years with the previous internet provided which was delivered via Hybrid Fibre/Cable to a ARRIS CM8200 cable modem, feeding a Telstra Smart modem 3 which did a NAT of the WAN IP to a private IPV4 of 192.168.0.1/24, DNS was Cloudflare Family (1.0.0.2, 1.1.1.2) and a DHCP range of 192.168.0.2 to 192.168.0.254.
We have signed up for a new internet service delivered by a mobile 5G service. The carrier provided router is Nokia Fastmile 3 model 5G12-13W-A.
The issue is that the orbi does not obtain an IP address when the WAN port of the ORBI is connected to any of the LAN ports on the Nokia fast mile. The WAN IP address of ORBI show as 0.0.0.0 and the light stays purple. All ports on the Nokia Fastmile are confirmed as known good, as is the CAT7 ethernet cables. The same Cat7 cable as ran between the Nokia and the Netgear Orbi can be plugged into my HP zBook ethernet port, obtains an IP and speeds of around 400/140
If I set a fixed IP on the orbi, and reboot, without connecting to the Nokia to the WAN port, the ORBI will show the fixed IP. Plug the Nokia into the WAN port, and the IP address clears to 0.0.0.0 leave the subnet mask and default gateway.
There is only limited options available on the carrier firmware on the Nokia, there is no option to place in bridge mode.

Does the ISP router show the RBR as being connected to the ISP router on it's web page somewhere?
Does the RBR show a connection rate being seen on it's web page under Advanced tab, show stats button?
Wondering if connection rate between RBR and your ISP router isn't working right.
Happen to have a non managed 1Gb LAN switch that you could put in between the RBR and your ISP router and connect only these two items to this switch?
Your ISP Modem already has a built in router and wifi. This would be a double NAT (two router) condition which isn't recommended. This would be a double NAT condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAT

Couple of options,
1. Configure the modem for transparent bridge or modem only mode. Then use the NG 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 NG router gets from the modem. https://kb.netgear.com/25891/DMZ-on-NETGEAR-routers
https://kb.netgear.com/24086/How-do-I-set-up-a-default-DMZ-server-on-my-Nighthawk-router
3. Or disable all wifi radios on the modem and connect the NG router to the modem, LAN to LAN configure AP mode on the NG router.

Try option #2 first...
If normal connection doesn't work, try option 3 for AP mode.
Your also behind on FW as well...something to update FW and see...
>> Configure the modem for transparent bridge or modem only mode. Then use the NG router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly. RES: Unable to set to bridge, the IPS firmware does not offer this option. Additionally, the previous ISP setup (HFC Cable --> Arris CM8200 --> Telstra Smart Modem 3 --> Netgear Orbi 960 also had a dual NAT. The Telstra smart modem presented 192.168.0.1/24 to the WAN port of the ORBI, which then did a second NAT to 10.0.0.1/24. This was functional without issue for 2 1/2 years.
>> 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 NG router gets from the modem. RES: The ISP firmware is very limited, there is no option to disable the WiFi, only to set the SID and Password. It is only possible to disable the guest WiFi and set guest WiFi isolation on or off. No option to set a DMZ.
Seems that this new ISP modem maybe the issue. Nokia Fastmile 3 model 5G12-13W-A
Something to ask the ISP about to see if they can disable WiFi on it.

The original post does not specify:
- What became of the Arris and Telstra equipment. They are no longer connected, correct?
- What 'mode' the Orbi system is in. ('router' or 'access point')
At some point, it might be a good idea to update the Orbi firmware to the current release (v7.2.8.5) satellites first, router last. The system does not need to be connected to the internet for this process. Just download the installation files from Netgear and perform the update while connected to the satellites and router locally.

Although a Factory Reset on the Orbi system can involve a bit of effort (about two hours of tedious typos in my case), when "things aren't right" sometimes a Factory Reset is appropriate.
- What became of the Arris and Telstra equipment. They are no longer connected, correct? RES: Correct, they are no longer connected, and the contract with the previous ISP has ended. The Telstra Smart Modem 3 has been returned. The Arris Cable modem is still connected to the HFC cable, but is powered off.
- What 'mode' the Orbi system is in. ('router' or 'access point') RES: Orbi 960 is in Router mode.
Thanks for the response. Very strange. There is a remote possibility that the gigabit LAN ports on the Nokia Fastmile 3 model 5G12-13W-A are not compatible with the multi-speed WAN port on the RBRE960 router. Ethernet ports contain internal software which enables each adapter to 'probe' the other adapter and determine the maximum speed that they both support.

This might explain why the HP zBook is able to connect but the RBRE960 router does not. A quick test would be to put a non-managed gigabit Ethernet switch between the Nokia and the Orbi. (gigabit switches are really inexpensive. 5-port models are under $20 on Amazon. My "box of stuff" has at least a half dozen that I have collected over the years.)
I dug out a 16 port 10/100/1G switch. connected it between the Nokia FastMile and the Netgear Orbi, and plugged the HP zBook into another port on the 16port switch. zBook worked fine, and so did the Orbi.
As a confirmation I removed the switch and plugged the HP zBook into one port on the Nokia, and the Netgear Orbi into the other port. HP zBook worked fine, but so did the Orbi!!!!!!!!!!!!!!!!!!!!!
This was the first time that the Nokia connected to the Orbi had worked. After some experimenting this is what I discovered.
Nokia --> Netgear Orbi using a CAT7 (known good cable) Doesn't work.
Nokia --> Netgear Orbi using a CAT6 Works perfectly! Orbi statistics page shows a 1Gbps WAN connection, internet test speeds within expected range for a 5G internet connection.
Nokia --> Netgear Orbi using a Cat5e Works Perfectly! Orbi statistics page shows a 1Gbps WAN connection, internet test speeds within expected range for a 5G internet connection.
Tried 4 different cat7 cables from 3 different manufacturers, all know good cables, 1 brand new out of the manufacturing package, none of the 4 CAT7 cobles would work, tried several CAT6 cables and they all work fine.
Seems like a cabling issue. I've only used CAT6A STP and recently bought some CAT8A STP cable from Amazon. Zero issues with my RBR960 when it's online. I've never tried CAT7 anything.
Glad you seemed to narrowed the issue down.

and......... the prize for most unexpected discovery has been won! We have all been led to believe that "newer is always better".
Ha!
Thanks for reporting these results.
Of course, the next question is, why? Neither CAT6 or CAT7 ethernet cables have any smarts in them, CAT7 has individual pair shielding, and shielded jacks, I can't see any of that making a work/no work difference for a device to device on a 90cm patch cable. But the evidence suggests otherwise.
And these were not ebay/Tempu elcheepo hit or miss cables, I only use commercial grade cables from a major cabling wholesaler.

Is it possible that the connector isn't fully seated into the 960 socket?
