I just installed a brand new AX50 in router mode and wired it up with an second AX50 in access point.

If I log into to the main router it shows under "network map/basic,wired clients is shows not only my wired clients but also severall wireless clients, such as Iphone, google home mini etc.

What is wrong, how can I change this?

Both the router and access point are new, and latest firmware is installed.
