I have a older Linksys router, I have it set to only allow my MAC addresses I add to it but when looking at the DHCP leases I see a MAC address with a IP that I don't recognize and is not in my MAC filter list.
Is there a way I can determine exactly what this device is or if it is someone that should not be connected? I have broadcasting disabled too, and WPA2.
I tried RDP and web browsing to the IP but could not connect. I don't think the IP would ping either.
P.S. Something else I need to add it I just installed a Intel Dual Band Wifi AC Adapter that is also a Blue Tooth receiver. I dind't really check before installing the card and when setting up the new MAC I noticed the DHCP lease that I didn't recognize. Is there a chance that could be from the Blue Tooth card?
