CablesOnline 6-Pack 10/100 Ethernet Loopback Plug, Pinout 1-to-3, 2-to-6, Gray TS-UL01-6

While I am an IT Professional, I got these for an unusual use case; Plugging one of these into the Ethernet port on my older Vizio "Smart"TV, I was able to disable the built-in Wifi. From experience, many smart TVs don't allow one to disable to the Wifi, since that renders the "smart" features unusable. However, many of them do have built-in software triggers whereby if a physical network connection is detected, the Wifi will be disabled. Our Vizio TV stopped getting firmware and app updates 2-3 years ago, and the built in apps are slowly ceasing to function as the vendors (Netflix, Amazon, etc) update their backend services making them incompatible. We've since upgraded to an Amazon Firestick for our streaming services (which is overall a nicer experience than the slow TV apps), but without a way to disable the built-in Wifi, the TV was still broadcasting out, adding interference, and grabbing an IP on the network, but then not doing anything else. Since these plugs register as a valid physical connection, they switch off the Wifi and therefore disable all now-obsolete smart functions. I only needed to use one, but having extra will be useful in the long run. If you're struggling to try to turn off the Wifi on your smart TV, I highly recommend these!

Worked as expected.

does what their supposed to do...terminate.

Works! A++++!!!
