Orbi struggling to get IP address/DNS from fixed wireless ISP

I'm replacing my Asus router (RT-N66YU) with this RBR50 unit. I live in a rural area and use fixed wireless service from my ISP (a 2.4 GHz line of sight system). This means there is a radio (powered with power over ethernet) on my roof that communicates with my ISP.

 

I have been working with my ISP for a few days as ORBI is having difficulties properly connecting to my ISP system - meaning that it doesn't get a IP Address (via DHCP) or an DNS server address. My old router continues to work just fine and if my ISP reboots my radio (which they can do remotely) ORBI gets this information just fine and all is well.

 

However, if I ORBIT is then power cycled (or the network cable is unplugged from ORBI), ORBI will no longer get this information from my ISP unless my ISP remotely reboots my radio. Simply power cycling the radio myself doesn't help.

 

I realize this is a complicated scenario, but I don't know what to do. My ISP has other customers using ORBI (that they know of) and are not aware of this issue. How do I proceed? Any settings on the ORBI that you can suggest changing? My firmware is already up to date.

    When you tried the router's MAC address cloning or "use this MAC", have you rebooted Orbi and the radio eqipment then?

    Some ISP's remember the MAC address of the first router and does not accept any other request from other MAC addresses (for security reasons). Since you had the ASUS working earlier, so this is a good troubleshooting step to make sure is tested.

    What FW is currently loaded?
    What is the Mfr and model# of the ISP modem the NG router is connected too? If you can get this information. Does there radio on top of the roof have any router built in or is it just a modem or device that has a LAN interface for a external router?

     

    Try disabling the following and see:
    IPv6

     

    You can set manual DNS ON the Orbi router, try 1.1.1.1 and 9.9.9.9

      V2.2.1.210

      This type of setup doesn't have a modem - the radio simply connects right to the Internet port on the Orbi.  Orbi acts as a router.

      We've tried the IPv6 thing and the fixed DNS - no help.

        Can you reinstall the prior router, turn OFF it's wifi radios, connect the Orbi router to the other router and configure Orbi for AP mode?

    Which Ethernet is power feeding the radio?

      The POE unit is new (ISP replaced just in case) - this did not help.

        Ok, but where is the Ethernet cable that is feeding the POE unit coming from?  

        Do you have any link to the radio unit product description?

  • How do you have the Asus configured? I mean, do you have a username and password configured for it to connect ot the ISP? PPPoE? PPTP? L2TP? If one of those, what connection mode do you have it set to? (always on? dial on demand? manually connect?) And you had both the Asus and the Orbi set to use DHCP for IP address assignment? Have you tried telling the Orbi to release and renew your DHCP lease? (available under Advanced > Administration > Router Status > and then hit the "Connection Status" button)

     

    Maybe you should try cloning the Asus router's WAN MAC address on the Orbi and see if that helps?

      I tried cloning the MAC Address too - no help.


      Regarding how the Asus is configured:

      >> I mean, do you have a username and password configured for it to connect ot the ISP? PPPoE? PPTP? L2TP? If one of those, what connection mode do you have it set to? (always on? dial on demand? manually connect?)

       

      No to the username/password question.  

       

       

      >> And you had both the Asus and the Orbi set to use DHCP for IP address assignment?

      Yes

       

      >> Have you tried telling the Orbi to release and renew your DHCP lease? (available under Advanced > Administration > Router Status > and then hit the "Connection Status" button)

      Yes, too many times to count

        When you check the INTERNET PORT STATUS in the web GUI (where you renew the DHCP lease), what is the status of the internet port as seen by Orbi? Can you take a snapshot of the port status when the problem happens.
