I have an annoying issue in my network. My router shows (besides the devices I know) a "Remote" with access to internet and within the private IP range of the router I use. A mac address is given, could be some gimmick phoning home, malware or some other problem. But....how can I trace the culprit. Currently I blocked internet access of it. None of the devices I use seem to notice, so it would be good to understand how to understand who "Remote" is. I have the doubt it might be the outdated Loewe TV I have at home, running a stone age - Android (about 15-20 years old I guess). As it is branched via a d-Lan device like all the others, maybe that is it, however, how could I get the device more talkative or identify it better within my network? Any ways to track / trace with the IP and the MAC the actual device? What software would I use and how would I proceed. Thank you.
