Orbi DHCP Range

I have my Orbi configured on a /21 subnet, I want to be able to configure the third octet of the DHCP range but seem to be able to from the web interface. Is this possible?   Thanks

    As you may have noticed, the DHCP configuration entries allow the user to specify the start and end IP's in the 4th octet.  (The first three octets are greyed out.)  My understanding is that this creates a maximum pool of 255 DHCP addresses.

     

    There is an article in the Knowledge Base that gives advice about number of client devices: https://kb.netgear.com/31097/How-many-devices-can-my-Orbi-system-support  In that article, Netgear says "about 250" devices, but warns thata too many will impact performance.

     

    Note that you can change the third octet of the subnet mask to /21.  That would allow you a maximum of 255 DHCP assignments and allow you to use static IP's for the other devices.

     

    You probably have a good reason for wanting more devices.  Care to share what it is?
