Haven't seen this before, but my Tesla in the garage has a full/great connection to Wifi it seems. It obviously also uses only 2.4ghz networks. I believe I know what IP it is as it and one other device are the only wireless 2.4 devices connected - BUT... is there a way to ping the car or identify it otherwise. If I'm right it doesn't use any identifier/name at all. I can just seen what IP it is assigned.
