Question: does it have to be a smart tv? or can any tv with an ethernet port work
Document: i have a smart tv with wifi but i could not get it to work so i bought this thing and it worked fine.
I use 2 of these to download Direct Tv's VOD shows by connecting it directly to my Direct Tv receivers. As other reviewers mentioned you need to plug these adapters directly into your ethernet port to access their settings. Sometimes a bit difficult to set them up but I eventually was able to.My biggest complaint is that I have to unplug them except for when I want to actually use them.
I think I have ordered a half dozen of these for myself and others. Simply put, if you have a device that has an ethernet connection, this little device will enable it to connect to your network, wirelessly. You don't even need an A/C outlet if your device has a powered USB port. Wirelessly network a printer. Connect your smart TV without running cables. Connect your Tivo to 802.11.n.
This product worked just as promised. Even though it is refurbished the pakcaging and product are impecable. I  would highly recommend it to anyone. So far no glitches at all, it works perfectly with my smart tv.
I purchased this device to connect my smart tv to my wireless network. Setup was a breeze and it works great with my Panasonic Viera LCD. Would recommend to anyone looking to save money on a wireless adapter for their smart tv.
This works great for me. I am using it with a Yamaha V673 receiver. The only bad thing if you are not using this with a computer is  if your change your router settings (like your SSID). You will then need to get a laptop and connect this to the laptop, set it up again and then plug it back into your device.This will work with any device that has an ethernet port and no wifi adapter built in.
Let me start off by saying that I'm the techie guy whose friends and family call to fix their computer issues.I bought this to add to a sprinkler system controller that only had a wired ethernet port when I needed wireless.I bought the refurbished one as these devices have no moving parts so they generally either work or don't work and there aren't any motors or moving parts in them to go bad.I received the adapter in plain cardboard packaging with a netgear logo on it.
they should not call it universal if it doesn't work with some  electronics, did not work with my sony bravia tv.
It is used to connect direct tv dvr and 2nd receiver router while it need to be reset alot it does work well
Did not work with my Direct Tv Reciever, so I guess its not totaly universal like advertised, it seems like a good idea but like I said did not work for me
Answer: It can work on any device with an ethernet port.  Of course, it just provides the connection.  No apps.
