It's important to understand how this device is intended to work so that your expectations are properly set. An inexpensive extender of this type receives the signal from your main wifi router, and rebroadcasts the wifi data on a different signal, with its own SSID (the name for the signal you see on your cell phone when you search for a wifi signal in Settings>Wifi). This device creates that new SSID by appending _EXT to the name of your main wifi SSID. You'll often see both SSIDs; you should pick the one that will do the best for you depending on where you are in your house. Your phone might change between the two signals on its own, but you'll soon learn which signal covers best in each location in your house.Key to the operation of devices like this is that it be placed in a location that 1) allows it to receive a decent signal from the main router, and 2) covers the area of your house that is not covered well by the main router. If instead you locate the extender directly in the area with poor coverage, it will receive a poor signal from the main router just like your phone does. It won't be able to efficiently transfer data from the main router in that location. Think instead of placing the extender half-way between the main router and the area you want the extender to cover. You should experiment with different locations, bearing in mind how many walls, floors, or other obstructions lie between the extender and the main wifi router, and also between the extender and the area you wish to improve.The second important point to understand is that extenders of this type operate in a "half duplex" mode, meaning that at best, the data rate from the extender will be half of that provided by your main router. If you are already using most of the data capacity of your main wifi router to a certain device, it's unlikely that you'll be happy with the extender signal. In my case, I saw around 50 MBps from my main router when I was near the extender, and around 25 Mbps from the extender itself. This is more than enough for my casual web surfing, and youtube watching. Your results may be different.Of course, for significantly more $, you can change out your existing wifi router for two or more "mesh" routers. These routers are able to move full speed data between each other, and you can add units until you have the coverage you require. You'll see only one SSID, and your phone should move easily from unit to unit. But at this extender's price point, I got the coverage on my deck and in the corner of the family room that I needed.This item does not incorporate the fastest wi-fi specification. If your needs are more data speed intensive, you might go for a model with higher specs, for a modest increase in price.Setup was very easy. I used the PC method because I'm loath to put another app on my old 16GB cell phone. For that reason, I can't comment on the app.

Nice product! As others said, it is indeed easy to setup and configure as there are detailed instructions. It boosted the signal pretty good both for a PC and mobile phone. I took one star off as there is no information about the manufacturer or the website where a firmware upgrade file can be downloaded. The manual says download "from our website", but none is provided, that's odd! When I searched by the device name, "WF8500", I found only a closely related (by item name) Samsung washing machine and Epson printer in top results... When I attempted to go to slopehill.com (the Amazon seller "slopehill"), this web address was not valid (actually listed for sale), so it must be not the manufacturer name. No clue from the item itself, its box, enclosed instructions or description on its Amazon web page. Fortunately, a firmware upgrade is optional step, and the WiFi signal was boosted already. There was a couple of other minor issues. 1) The Installation Guide says that before starting, check if there's anything missing in the package, and contact your dealer of purchase to claim for missing items: 1xWiteless-N Repeater, 1x RJ-45 Networking Cable, 1x Quick Installation Guide. RJ-45 cable was not included, but I don't see on the Amazon product description page. This option (using a a cable) is optional, and you can configure a new network wirelessly, or use your own RJ-45 cable, but the Guide seems outdated as is. Ok, the repeater is cheap already, fair enough :-) 2) There is a "USB charging interface" on the Repeater from both the Amazon product page and Installation Guide, but it's function is not described. I presume it is not required for charging the device, but possibly provides an option to connect to a USB port to power this Repeater if there is no AC outlet? 3) The Amazon product description listed 2 other features - "Guest Mode" and "Fast Charge", but these are not addressed in the Quick Installation Guide (and no website address as I mentioned above).Within our apartment we lose signal in one of the back bedrooms which just happens to be the master bedroom. This obviously creates issues if we want to watch YouTube while laying in bed which is why I wanted to get a Wifi extender to see if we could boost the signal. Upon plugging the booster in and running a speed test we saw great improvements in both upload and download speeds in that room. Purchased this wifi extender to help get a stronger connection for our skybell wireless doorbell. We were getting laggy videos and slow alerts when we had a recorded video. My husband purchased this wifi repeater to hopefully get the skybell functioning at at least 85-90% for better videos and faster alerts. My husband was able to set up the repeater as an extender very easily. The instructions are easy to follow and within 30 minutes we had it completely set up and plugged into the outlet nearest the skybell, we are now getting 92%. We tested the videos and alerts and all are working as the should. Before getting this extender we were thinking of returning the skybell. This extender was what we needed to complete the doorbell upgrade at a great price. I recommend this repeater to anyone needing an extender or access point to add to their existing wireless network. You won't be disappointed.

Tengo Internet por cable en toda la casa, para poder conectar aparatos sin perder nada de velocidad donde sea.El problema era la señal WiFi para el teléfono, por eso adquirí este producto. Lo enchufé en el comedor y con el switch con el cable hace de repetidor de señal.Ahora la señal de WiFi me llega perfectamente al comedor.Funciona perfectamente y conseguí hacerlo funcionar sin ser un experto en telecomunicaciones.

Macht was es soll. Preis Top. Was ganz gut gefällt: es kann ein Zeitprofil aktiviert werden das das Wlan nicht wärend der schlafenszeit umher Funkt.Ein kleiner Tip:Es ist in der Beschreibung nicht beschrieben, den Wlan Kanal beim Router fix vergeben nicht auf Auto einstellen sonnt kommt der Repeater nicht ins Inet.Tolles kleines Ding das sein Geld Wert ist.

non so se è il mio che ha dei problemi ma mi sto trovando malissimo. la configurazione senza vps con il modem telecom è da impazzire, col pc ha funzionato una singola volta per una mezz'oretta e poi ha smesso, con un galaxy s8 mai visto. il tasto reset sembra non funzionare sempre. inoltre la presa della corrente non è orientabile cosi che le antenne sono sempre rivolte in basso e in alto facendo si che la potenza del segnale vada per i vari piani invece che diffondersi nel piano.mi spiace ma pessimo acquisto anche concettualmente parlando
