Unknown Client on LAN

[cdikland]

All the clients on my lan have been assigned their own local IP. From time to time I get an unidentified client showing up on my Network map. Always the same local IP/MAC however that is all the info I get (i.e. no manufacurer). When I refresh the list the client is no longer there.

Is there a way I can determine where this client is coming from? Alternatively, can I block this client via MAC address??

What router do you have? Most have the functionality to do MAC filtering, either allowing or blocking certain addresses.

How do you have the 2 routers setup? Could it be one of them? You sure its not TV's, Game consoles, etc? Do you have WPS enabled on your router?

N66U - Router
AC66U - AP
wps enabled - no

Any wireless/hard-wired device in my home is assigned a local IP. There should be no clients in the client list I dont have a record of, either by IP or MAC address

What is the vendor code (first 3 octets of MAC)?

And is it shown in the DHCP lease list? (System Log, DHCP Leases tab)

Not on any of the official lists, but I found some evidence that suggests this range is assigned to Kindle. Do you have a Kindle in the house? If so, check to see if it's mac matches.

Well, yes, we know how that 'fairness' stuff goes with our better half (our toys are usually more expensive anyways).
