T3200 modem and wifi extender issue

[wireless]

I have T3200 modem and a wifi extender, all our devices are connected to the modem. I can see all our devices from the modem gui (192.168.1.254) under the home network while from the wifi extender gui, I see only one device (192.168.1.254), no unknown device under the network stations list. 2.4Ghz and 5Ghz associated clients will always display 0 but lately noticed that it always display 2 on 2.4Ghz associated clients, although I see one device only (192.168.1.254). Does anyone know why it is showing 2? Does it mean someone connecting to my network, hiding their ip address? I called technical support but they don't know why.
