Orbi 772 backhaul through MoCa
Hi everyone, I hope someone can help point me in the right direction, because both I (and Copilot, Gemini, and ChatGPT) have run out of ideas. I recently purchased a new mesh system (Netgear Orb...
ISP = Internet Service Provider
CPE = Customer Premise Equipment, rented to say the device you designate as fiberbox
NAT = Network Address Translation - the system that "hides" your private LAN from the public IP address assigned by the ISP - this way your private RFC 1918 LAN IP adresses (I guess your Orbi uses 192.168.1.1 on the LAN port by default.
WAN = Wide Area Network, the network coming to your home on that fiberbox.
Isn't the plan to operate your Netgear Orbi Router as the one and only router to correct direct to this fiberbox? In my option, there should be no other NAT Router (like that TP Link one) in the data path between your LAN with your router (here the main Orbi Router (the Orbi with the port marked Internet (that's technically the WAN port!)
But first, you must physically split your LAN and the Orbi Router Internet port - only establish a direct dedicated physical connection to the Fiberbox.... Otherwise, you will never come away from all te issues you certainly have by interconnecting the WAN and the LAN - because your MoCa is basically physically a d logically connected wrong.
How far is the distance between the Fiberbox and the Orbi Router? The most simple connection would be a simple RJ45 Ethernet cable (max length 100 meters) - and bit connecting your MoCA network to the Fiberbox and the Orbi Router.
Take that other TP-Link router out from the network please.
Just curious, where are you located? Wild guess it might be Denmark 8-)
In Denmark, a fiberbox (commonly referred to locally as a fiberboks, ONT (Optical Network Terminal), or Fiber KAP / KundeAfslutningsPunkt) is the wall-mounted device that converts optical light signals from the fiber infrastructure into electrical signals for your home network.
Reiterating thugs a little bit more: As you apparently have a fiber Internet connection - you still appear to have some Cable TV in your home. Or is that MoCA not connected to your Cable TV provider network? You see, I'm still concerned you might disturb the Cable TV network with that MoCA installation in case you are outside of the US.
Coexisting with Active Cable TV & DOCSIS Internet
If your home actively uses coaxial cable for DVB-C TV and DOCSIS cable broadband from a provider like YouSee or Stofa:
Frequency Plan & Compatibility:
Traditional DVB-C TV & DOCSIS 3.0:
Cable TV and legacy DOCSIS 3.0 operate below 1002 MHz. Standard MoCA 2.5 operates in Band D (1125–1675 MHz). In this configuration, both services can coexist on the same physical line without overlapping.
DOCSIS 3.1 / Extended Bandwidth: Danish operators (like the most common Cable TV providers here in Switzerland!) using high-split DOCSIS 3.1 configurations can extend downstream frequencies up to 1218 MHz. This overlaps directly with MoCA Band D, causing packet loss, modem desync, or complete loss of connectivity.
Here is your complete infrastructure - nothing more is required my friend (Gemini helped a little bit here):rejected - this AI generate graphic does not reflect the standalone MoCA between the Fiberbox ONT
A great network:
- Provides more WiFi coverage (three access points vs. two)
- Allows the MoCA adapters to use the entire bandwidth for router/satellite communication
except......... It requires purchase of a second Orbi RBE770 (about $400USD including tax & shipping)
It would be less costly to start with using two pairs of MoCA adapters
- Low Band to connect the TP-Link with the Orbi router
- High Band to connect the Orbi router and Orbi satellite
Once this has been demonstrated to function:
- Switch the Orbi router to 'router' mode
- Duplicate any TP-Link "router settings" on the Orbi, such as
DHCP pool, reserved IP addresses, any ISP login requirements, etc. - Bypass the TP-Link and connect the fiber modem directly to MoCA Adapter
Nope: Only ONE Orbi system involved my friend - one Orbi router, and as many satellites as required.
Don't understand why you are still hocked to the idea of integrating that addiitonal TP-Link NAT Router. The one and only Orbi RBE770 is the only NAT router ever required here.

Not at all. I agree that there should be no need for the TP-Link router. Since its WiFi is not active, any functions that it performs can be done by the Orbi router. (I am not as offended by "Double NAT" as some on the Forum. Thousands of people get along perfectly well with Double NAT.)
As the OP stated that the coax would be used only for internet (no cable TV), it seems to me that using two MoCA frequencies allows the network to function with one Orbi router and one Orbi satellite, thus removing the need to invest in another satellite.
Once the Low/High MoCA has been proved to work, then it is a straightforward (but not trivial) process to remove the TP-Link router. If by some chance that MoCA strategy does not work, then the OP is faced with more expensive options. (moving the fiber modem, running cables, purchasing a satellite, etc.)
