Additionally, there was 1 mac address with no other information such as an IP address or system name, just that MAC on a row all by itself.I had been looking for our DVD player which has the ability to view streamed movies and I think this might be it.https://ouilookup.com/ will take that MAC and let you know which manufacturer has that block assigned.My question is, did the link she went to on the computer or maybe her iPhone use javascript to get our WiFi password and if so, how did the player get the authorization to use our WiFi?1. It found an open wifi network 2. It's plugged into your ethernet 3. Your wife gave it the wifi passwordI am just curious about how did this work and could a person cause it to log on to our WiFi network and receive a video stored on a system here?Quite possibly. The systems for this is called several names, but the most likely are UPNP, DLNA, ChromeCast or AirPlay.What I am actually thinking of is more like a DVR where a computer can record a TV show like the old-school VCR's and then one could play it back through the DVD player on the network.Suitable Debian packages include: mythtv vdr kodi and for music, many others.This player can also update it's firmware when necessary and we've never been prompted from it for a WiFi password. It just seems to be able to get through when it needs to.That's suggestive of already knowing your wifi password or being on a wired network.
If there is no ethernet cable attached to the player, you could try to reset it to factory default and try to reconnected to your network. -- John Doe
