I am no expert but I stayed at my cousins house this summer and they had something like this. I know nothing about it, seemed to work ok with my devices. I have no clue why they needed this. I would first see what's wrong with the wireless before spending money on these gadgets. Some one here will know better. Mary

Yes, that is what I was looking for. Thx. But no, I too am not going to debug the problem as I was instructed to just get him one of these guys by Santa. Hee hee hee.

Is the problem the wifi signal reception or the wifi circuitry of the TV? I'd try moving the router first to see if you can get a better signal to the TV. Check the signal using a smartphone placed where the TV is. If the signal is strong but the TV isn't happy with it, what you may need is an external Wifi antenna that you can connect to the TV with an ethernet cable.

The linked to product isn't necessarily what's needed. A standard powerline system has two identical wall warts - one gets plugged in near the router and is connected to it with an ethernet cable. The second wall wart is plugged in near the device needing a network signal - an ethernet cable is then run from it to the device, like the TV.

What was linked was a bit of a hybrid - it's two dissimilar items. One is a regular powerline device to take the signal from the router and put it into the electrical wiring. The second device takes the signal from the wiring and then broadcasts a wifi signal in another part of the house. It's like a wired range extender using a powerline system.

Powerline nics don't work in all homes, especially if the home has two (or more) phase electrical power and the two sockets aren't on the same phase. Also, you can't plug them into patch cords/surge suppressors. Try it and see, but in case, buy it from a retailer that allows returns without a restocking fee.

I do not have the details. I am aware from comments that the router was powered off and moved to no help. No one here has a smartphone to use but I already bought one of the powerlines from Netgear. Thanks anyways.

I tried Powerline and it didn't work for me but it does best in newer home with modern, basic wiring. Another option is what's called a network extender but they have limitations too. The easiest/best solution is what's called "mesh" networking but such systems are still kind of expensive. If your friend is able to physically run an Ethernet cable from his existing router to another location, there's a way to extend the network relatively inexpensively.

I know when my router is giving out the Wi-Fi doesn't work well and it's time for a new one. Have you tried that ? Please post back how it works. Mary

luis, you can't fix something if you don't know what the problem is.

As I suggested, you need to first see if it's a signal issue at the TV location and the easiest way to do that is with a smartphone. If you don't have one, you must know someone who does, who can come over and, using a Wifi signal testing app (they're free), check out signal strength throughout the home. Short of doing that, you're only guessing what the problem is and the approach you take may or not work.

Also if no smart phone any one with a tablet or laptop. If the router is provided by who ever they hve their internet through I would hae them come and check. You can't just take someone's word it doesnt work without knowing why. Mary

Right, sorry I forgot. A tablet would work but maybe not a laptop (which could be too large to maneuver around).

Yes it would be big but as long as it's wireless better than nothing if that's all they would have access too. Mary
