RBR850 - add on satellite no longer available, how to add a previously used satellite
I have an RBR850 router with 2 satellites. I needed a third satellite, but am told this is an old model and not available anymore. So I bought a used add-on satellite, and reset it. But I can't se...

did you get it fixed?
might try hardwiring the satellite to the router and leave it for a bit. Then see if it syncs and if you can get in and access it so you can update it.

Thanks for all the suggestions. I still can't get it fixed.
Is it because I am using a mac? Because the mac doesn't have an ethernet port, I have to use an adaptor,. When I go to settings and network, it will say the ethernet is not connected and changing the IP settings doesn't help. When I go to the USB/LAN connection and try to change the IP address there to 192.168.10.49, I can't access the internet from my mac anymore. Even if I ignore that and proceed to the next steps, when I try to navigate to 192.168.10.250, I get an error message (site is unreachable).
I tried to navigate to 192.168.10.250 using a pc, but that didn't work either.
I also tried to just hardwire the satellite to the router, but it still couldn't sync.
Any other ideas?

This is correct. In order to use this technique to push firmware to a device, both the device and the computer being used to "push" must be disconnected from the local network. With only the two devices connected together, they can communicate with each other. After the "push" has been successful, then both devices can be reconnected to the network.

This might make the entire discussion "moot". Unless a static IP address and subnet mask can be set on this Ethernet connection, the TFTP process cannot be done.

Thanks for pointing out that an adaptor might not work. I switched to a laptop which has an ethernet port and connected the laptop directly to the satellite. Also managed to change the static IP address and subnet mask, and followed all the steps in the documents shared on this thread (thanks to all!). But I still can't get to 192.168.10.250. I made sure that only two devices were connected together, but I still get a prompt to say the page is unreachable.
Is there any other way to update the firmware? (syncing directly with the router didn't work either)
