I can't decide if the weirdness I'm seeing from a #Vizio TV on my network is just my #dumaOS router being funny, or some oddity of the network extender... ... ... but it briefly looked as if the TV was assigned an IP and broadcasting some Vizio specific tech but using the #macAddress of the extender.
I'm not overly prone to paranoia but I'll just keep an eye out, keep the TV blocked, and see if "other" mac addresses start popping up.
