Address reservation table not working

Hello

 

I have 20 address reservations for my ORBI. I recently changed the DHCP end IP address from 0.254 to 0.200. Now my address reservation table is not working. All of the MAC ID's from the table connected to ORBI are assigned random IP address.


I tried to delete all of the address reservations and only add a single reservation, still that does not work. The MAC ID for that reservation is assigned a random IP

 

Please help

    Please set the IP address default pool range to .100 to .200 or change back to default DHCP pool range, then try IP address reservations.

     

    What model# Orbi system do you have? 

    Firmware version loaded?

      It is an RBR50

       

      The pool range is set from 0.50 to 0.200. Sorry - what are you suggesting I change it to ?

       

      I cannot extend it back to the default of 0.50 to 0.254, I have another router on the network which needs to use DHCP range of 0.201 to 0.254

        When devices broadcast a DHCP request, they accept the first DHCP server that responds.  If that server has no reservation for the MAC address, it will return a random IP from its "pool".

         

        Having two DHCP servers on the same LAN is a recipe for disaster.

    Can you confirm what appears on the first two lines of the LAN Setup page?
