@Bob111 Thanks for your reply.
Yes obviously Wi-Fi detective doesn't show MAC address. I'm using Archer AX23. My router clients list is fine. It's perfectly showing every single devices online and offline . However, when are switch to Wi-Fi detective. It scanned some weird IP address. I tried to ping and trace route those weird IP. But they are no response. So I'm not sure is it the Wi-Fi detective software problem because those weird ip only show once or twice. Next scan will disappear or maybe come up the other ip address.
I did a test. I static all my devices ip address from 192.168.03 to 192.168.09 total of 7 devices. I also reserved and blinded those ip address. Limited the range of DHCP ip address only from 192.168.0.1 to 192.168.10.
You know what Wi-Fi detective scanned?
I have one scanned with extra 192.168.0.20 and the other scan with extra 192.168.0.21. I have no idea why it shows this ip address even I already limited the ip address range from 1-10 only.
