I had bought this d-link wireless extender, because I was having difficulties going and staying online from my room. Once you step into my bedroom the signal went from 3 bars to two to a weak signal reading, sometimes the signal drops in and out. I had to walk out of my room to get a stronger signal. Now that I have installed this extender in my room, I can now get a strong connection every time! No more dropped signal or going in and out , or receiving a weak signal. The device was simple to install, just plug it in, press the button, and follow the instructions and you are online in no time! This is not a router! This is only used for if you have existing wifi but want to extend the wifi range in you home, office or wherever you want to put it. This is a must buy item, i recommend you purchase this if you have any area in your home or office that's is a hard to reach and gets a weak signal from your existing router, just plug in, do some configuring and you will have wider wifi range quickly and easy. Shipping was fast.. Got it in 2 business days!
