Orbi RBR50 Router Ports
Hello, I have an Orbi RBR50. I was told I need Ports 4500, 500 and 123 open to have something work on it (hard wired). Is there a way to open these ports? Do I need a new router? I need a T-mobi...

Thanks for the details. Let's review the setup instructions for this device:
https://www.t-mobile.com/support/coverage/4g-lte-cellspot-setup-and-help
The Orbi router does not block any UDP or TCP ports.
Notice "No port forwarding is needed." The T-Mobile device uses these port to open connections, not receive connections.
The next step is to verify that TCP ports are open.
Setup suggests using Windows PowerShell to check ports 123.500, and 4500. Here's what happens on my PC that is connected to an Orbi RBR50 & Spectrum cable internet:
So, "all good so far".
In addition, Internet searches for this cell spot and 'port forwarding' turn up numerous responses that no port forwarding is required.
Are you able to reproduce the same results with your Orbi router?
When you look at the Orbi web interface, Attached Devices page, does the T-Mobile spot appear on the list and say that it is 'wired' to the router?

Thanks so much for your help! Frontier won't help because it's not their router. Their router was terrible, so I got the Orbi with one satellite. It's beyond the service time, so they won't help either.
The only thing that shows as "wired" is Askey-AP5100W. I don't know what that is? The router itself? The Cellspot isn't listed. I tried a different cable, but that didn't help. I don't know how to check for the ports like you did.

If the T-Mobile does not appear as 'connected', then it is not likely to function. Askey-AP5100W appears to be a WiFi system from Singapore.

That T-Mobile Setup Guide indicates that the Ethernet cable packaged with the device should be used to connect the Ethernet port on the back of the device (#5 with the yellow jack) to one of the LAN ports on the back of the Orbi RBR50.
Normally, the product label will display the Ethernet hardware MAC address of the device in the form of hexidecimal numbers xx:xx:xx:xx:xx:xx That is the MAC address that should appear in Attached Devices
https://www.t-mobile.com/support/coverage/4g-lte-cellspot-setup-and-help also says that the Internet LED should be solid green.

I see our messages "crossed" in the Internet. If you have good T-Mobile service now.... problem solved!
