HAWKING HI-GAIN WL-150N USB DISH ADAPTR

I found myself just out of range of the Wi-Fi area at our favorite campground. I had heard that the "Hawking Hi-Gain wireless USB Network Dish Adapter" would help me, so I purchased it from Walmart. Couldn't be easier to install it to my laptop. Just insert the cd that comes with the Dish and it installs itself. Not wanting to get to the campground and then try it out, I tried it at home first. Had to get in the car and drive down the street to get out of range of my home wi-fi, using the laptop built in wi-fi antenna. I was out of range within about 400 feet. The laptop showed that I still had 2 bars out of 5 but when I tried to connect, it wouldn't. Just not enough strength of my Wi-Fi signal. I then turned off the laptop built in wi-fi connection. Then I plugged in the USB cord from the laptop to the Hawking Dish and pointed it toward my home. A window came up asking for my "password" which I entered so the dish would connect. Presto, it connected with the 5 bar signal! I drove the car down the street, now being at least 1200 feet, and still have a 5 bar signal. Kept going, turned down another side street. I'm now completely out of site of my home where my wi-fi is. Looking at the computer I'm now showing 4 out of 5 bars! Still able to surf the internet. I'm going to take an accurate guess at distance now being at least 1/4 mile away from my home! The dish is pointed in the direction of my home and the signal has to go through trees AND homes. No problem surfing the internet, this just amazes me! If you need to improve your reception of wi-fi on your computer, this product is for you. I have an HP dv7 laptop running Windows 7. I hope this review will convince you to buy this product from Walmart. I was told it would take up to 10 days for delivery. I received it in just 4 days. Picked it up at the Walmart store and the package was in perfect condition. I guess my main reason for the Walmart purchase was just in case I would not be happy with the dish, I could return it easily. But I will not be returning this. It works, actually works better than I expected!
