a couple of weeks ago my TV stopped connecting to my wifi network. I couldn't solve the issue (the names of networks still showed up on the TV but I couldn't log in to the Guest network). Disconnecting power, resetting, etc. didn't solve it. I think the firmware is up to date. The easy solution was to plug ethernet into the TV and that's what I did. I hadn't given the security implications any thought until I saw this. It seems like an issue I can't solve without some extra hardware piece, right? some sort of firewall between the TV and the rest of the home network.

I certainly haven't worked in this area but for years have wondered how people including fairly young children recognize a dachshund, a bulldog and a great dane as dogs and other things as goats, cats, etc. Dogs are amazingly varied in shape and size and color. It seems like a VERY hard problem.
