RT-AC86U Manually Assigned IP Limit is 64

[cptnoblivious]

Maybe examine closely your reasons for actually needing more than 64 entries on a home router? There may be other options or configurations that are better suited, or a higher end router.

This is worth highlighting.
We often jump to the technical solution instead of questioning what's the "question behind the question"

I think you can install from AMTM.

I find the config so much easier as I also use other custom settings in dnsmasq to integrate my Active Directory into my network.

Thanks for the tip! Although I have been using Merlin for many years, I was not aware of AMTM. The old saying - If it ain't broke, don't fix it.
I installed YazDHCP with AMTM and it works great! Very nicely done; what a great add-on.
It now says I can have over 200 manually assigned addresses.
Thanks again!
