I am confused. I am running on a RT-AX88U and with firmware 384.18. I manage all my devices on my local network using DHCP on the RT-AX88U. I was adding my grandson’s laptop to the DHCP table and this message popped up. I thought I could have 128 devices in the table.

I do have 64 devices in the table and get this message when I try to add the 65th device.

I uploaded firmware 384.19 to the router and same message.

What am I doing wrong?

I also thought that you can manual assign 128 devices, and not only the 50%.

I only have 54 devices under my rt-ax88u. I have not reached this limit yet.

Ok. Thank you Dave.

I am always using the DHCP Server tab under the LAN settings when I want to add a new manual assignment. ☺

All the more reason to not use the WebUI/nvram for assigning static addresses and using a dnsmasq.conf.add file.
No more limits to number of entries or (as of the 384 code base) number of characters.

@Xentrk created a script that makes it easier to convert the first time.

This assumes you are comfortable using the CLI and an editor like nano or vi.

At that number of devices, what's the point with manually assigning the DHCP lease? Just let the DHCP server do its thing...
