Yeah what's worse...

I have a LG modern TV. Smart shit. I also use a Linux install on a NUC. HDMI.

For some godsdamned reason, the TV was able to initiate an IP bridge with the Linux NUC and get an IP address on my network.

Nobody typed it in the TV. And I'm unsure how it did so itself.

What I do know is that Mikrotik allows DHCP-server blocks of wildcard MAC addresses. Blocked the whole fucking 24 bits of their allocation.

AND if it does get back online, I also shitcanned its routing on the IP side based on hostname.

This would be quite the scandal if you can substantiate/document it.

People always say, "jUsT dO nOt CoNnEcT your TV to you WiFi" which is asinine.

People say that theoretically TVs can get an internet connection through HDMI, but apparently none are actually doing so.

The only solution I suggest is physically removing WiFi cards from the guts before turning on.

    What?! How on earth would this work?

    HDMI ethernet channel is a thing, though semi-obsolete. It's unusual for a PC graphics card to support it. Intel website suggests they don't support it: https://www.intel.com/content/www/us/en/support/articles/000...

    Why is not connecting your TV to wifi asinine? Generally works fine but I suppose there are rumors that some TVs scan for open networks and connect to them automatically.

    It's going to be very unusual to find a TV using removable PC components like wifi cards. Another option is to connect it to your network but block it from the internet

      Because it doesn't prevent anyone else from connecting your TV to any other WiFi (and apparently that actually happened to someone according to their comment in another HN thread).
