For a while now, some random (non fixed) IPs just won't be listed in the DHCP client list, even though they show up in the WiFi Connect App.
If I reboot the RT6600ax (no need to reboot my linked MR2200ac), the "invisible IP" will now be showing up correctly in the DHCP list. By the way, I can ping the IP just fine, it's just not showing in the Network Center/DHCP Client
Anyone has that issue

See if you ping them in network tools, they should then show up in TC.
That’s what happens in 2600, and people say this is as designed…..
Which I don't understand, but I use other utilities to 'see' IP's so: "What, Me Worry?" ??
 
I have a similar issue where devices show no IP at all in Traffic Control but they have an IP and work fine. Unfortunately, I dont have a solution.
That's also the case for me in Traffic Control. That too I don't understand why, but as you, I confirm that all the "non IP devices" listed there have an IP (and their MAC can be retrieve with ARP, so all's good there as far as communication goes).
That behaviour in TC doesn't help me though, as I sometime still can't find a valid IP in the DHCP list.
 
Just wondering what you have set the LAN's DCHP address lease time to, default is I think 86400 seconds. I used to have a longer timeout that seemed to make my HP printer fall off the network, for purposes of Bonjour and couldn't stay accessible until the printer was rebooted. Anyway, I changed a few things and one of them was the lease time back to 86400.

I don't currently see any devices in Traffic Control or WifI Connect that aren't in the DHCP Client list. I have a few in DHCP Client list that aren't in the other two, but that would be because those wireless devices have been switched off or left the house. They will timeout eventually to release the IP address back to the pool.

Same: the standard 86400 seconds.

And now that I've added a DHCP reservation for ALL my devices, I can't reproduce my initial problem, which is good (I guess)
