I have owned a [competitor's] router for 3 years now. I was receiving poor connections and dropped calls on my VoIP phone. I started to do research online and decided to give your product a try. I am so pleased to say the installation was effortless. The speed is extremely GREAT!!! My laptop was still slow so I drove back the next day to buy the [Xtreme N] notebook card. It would not load at first because it was not Vista compatible. I called your number and was able to get an address to load the drivers from your support site. Downloaded and installed in a few minutes and BAM!!! 4 full bars... and speed I have never seen before. I will ONLY say great things about D-Link products and service. 2nd to NONE !!

Thank you for putting out such a great product. I admit a bit pricey...But having this much SPEED and RANGE was worth every dime.

Sincerely, a happy customer in SC
