5.0 out of 5 stars Long Range Wireless Adapter, August 16, 2009

By	Andrew "A.Andrew" (Caribbean Sea) - See all my reviews

This product works flawlessly straight out of the box. The installation was a snap. It works best with the small usb extension provided. I use it with an old Dell laptop to connect it to my new D-Link615 router. It connects my network between two buidings separated by a small area of tropical rain forest, a distance of more than three hundred feet,and through three concrete walls.I like the AES encryption for the enhanced security. This has got to be the best product for the price. I was really impressed with the performance..

5.0 out of 5 stars Great device to speed up wireless reception, November 14, 2009

I bought this device to allow my wife's Dell laptop to access our new refurbished Linksys WRT-160N router. Now I'm going to buy another to connect our kitchen computer. After installing the drivers the laptop found our network quickly and boosted speed from 54 mps to 117 mps. The USB adapter is a bit large, but the included USB cable makes that a moot point. Frankly for the money you really can't do much better.

Purchased this and received it quickly. A snap to install and works better than I ever expected. We have our office upstairs and our wireless router downstairs. Hooked it up to an older(2-3 years) desk top in our office and works like a charm. It's fast and at such a great price you can't get a better deal. I am very pleased with this product.
