I am sporadically experiencing the same thing off an on, but oftentimes it populates the same ones that it does not always populate. It's been somewhat of a task keeping up with the assigned MAC address for them all because the majority of my devices are in places that is not easily accessible without climbing sometim

This would certainly be excellent if it would readily find and list all of the clients all of the time

Ironically, on my AX6000, I get more stable results from the basic setup tab for client lists than I get on the advanced tab. I do not like using the DHCP page as it shows active leases, not necessarily active connections.  This is particularly true for IP reservations as I use them extensively.
