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 seem to pair it with my existing router.  I thought it's because the firmware on this used satellite is not the latest, but I can't update seem to update it either.  Any tips on what to do?

    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.

    I know its supposed to be 10.250 but try the old version of 192.168.1.250

      I got a alien RBS in 2nd hand. If I remember, I used the Add Satellite wizard on my RBR to get it connected wirelessly. In same room with the RBR and all other RBS turned OFF. It synced along enough to get and IP address and for me to log into it and get the FW updated to same version as the RBR. However with your RBS, possible FW on it is too old and not able to fully sync and ya, if older FW, the self assigned IP address would have been 192.168.1.250. Or possible that the RBS is just bad. 

  • I finally got the FW updated!  Somehow the IP address worked this time.  Thanks to everyone for your suggestions.

     

    I had bought second hand, one router and 3 satellites.  One of the satellites was an add-on satellite and I managed to get this to sync with my own router.  But the other 2 satellites which had come together with the router couldn't be synced, even after resetting.  I saw in other chats that one solution might be to reset my own router, but I don't want to do this for fear of something else going wrong.  Any idea how to sync these 2 satellites which had come together with another router?

      Which IP address on the RBS did you use for reference? 

       

      Same process. Try Add Satellite on the RBRs web page. You'll need ot have any existing RBS turned off while working to get one RBS connected, at a time. 

       

      If the 2nd RBR and RBS are working, I'd first ensure that the FW is up to date using same version as your first set. Then syncing 2nd set RBS to 1st set RBR should be less problematic. 

       

       

  • I used 192.168.10.250.

     

    Thanks for alerting that I have to update the FW on the second RBR, even though I won't be using it.  The IP address doesn't work though.  Is there a different set of instructions, to update the FW on the router?
