Orbi CBR 40 device issue

have you looked up what its mac address and IP address is? 

You can use the mac to see if you can identify it.

and you can use the ip to see if you can tell what device on your network it is by comparing your current devices IP address to that one. 

Does it show as a wired or wireless device? 

If wireless, what happens if you change the PW on the CBR to something different temporarily and not give it out to anyone. Does the device still appear?
