Question: Could you use two sets in the same house?
Document: The other box will go where you need an ethernet device to work and you have no cable there. Both boxes plug into the power outlet and use the power lines to couple the radio onto the power wires.SIMPLICITY. Folks, it just doesnt get any easier than this. There are two boxes - both are the same! You plug one into an ethernet jack where the internet comes into your house (cable, dsl, uverse, fios, even dialup if you have a switch or router).
No problems, no false starts, no regrets. This is a great product. (I do have one minor concern with what happened to my U-verse television reception during the process. The picture "froze" on two of the television sets that were on, but not on the third. It is not unusual for me to have this problem with my U-verse DVR, but this is the first time that multiple sets have frozen at the same time.
I've had Direct TV for almost two years, and never been able to use their On Demand service because I can't hook up the living room receiver to my bedroom wireless modem. This product is just what I needed. I plugged it in to the cable modem in my room, and the ethernet cable into the back of my Direct TV receiver, and I instantly had an internet connection that ran through my house's electricity. The ease of set up was amazing.
I've considered spending about $60-$80 for a wireless access point to boost reception, but then found this item. Not as convenient as wireless but more easily set up and working.Though I have zero(0) knowledge of electrical and wiring, I can see how my own 25yr old house has some interesting electrical wiring throughout. I tried two very different outlets and the internet connection was just fine.
Update - on alot of the vine products I get from amazon to review, I end up giving them away to friends and family who can use them more than I can. On this one, I kept it - it's so useful in my house not to stretch ethernet cat5 cable that it found a permanent home right here. Now on to the review.How do you run ethernet over powerlines anyways?
The reviews have been mostly great for this product that is supposed to extend the range of your wireless throughout your house. I was excited to get this as there are spots in our house that don't get the best signal when I use my wireless for my computer.The instructions were extremely simple to follow, even for someone like me (who is not very techy). The result for me was that the signal was not improved, and in some cases, it was worse.
- the last thing you want to do is filter it out! Just use a simple household outlet - that will be the best link. (you can still run the product on a UPS but it will loose the internet link upon power failure. )FINALLY THERE ARE PEOPLE WHO ASK "IS MY DATA SAFE" - yes - the power line devices stop at the transformer that services your house.
Admittedly, I started out somewhat concerned that plugging a device like this into the wall and then using it to extend my network could lead to shorting out some of my network equipment or other devices on the network, but in reality there is nothing to be concerned with.
It is pretty much plug and play. This assumes you already have your high speed internet, router, etc., in place.In a larger home with thick walls or signal interference this setup could be a viable solution or an addition to an existing set up.
From there you could, if you wished, plug in another wireless router on the remote end so you could provide stronger wireless coverage to devices in that area, or simply plug in a single device or connect to a network switch so you can plug in several devices at the remote end.
Answer: I no longer recommend Logitech equipment. All of my units no longer work properly. They're less than 2 years old.
