"It doesn't work !!!"
I tried to connect this Wireless Adapter on an Apple Network (Router) and It doesn't work at all. Even though the signal is Excellent this device is not working. I tried to contact XBox 360 Support Dept but They didn't answer my request. If anybody else had the same problem, I really appreciate any help.

"Fantastic..."
This product is great! I used to have a very long ethernet cable cable running about 40 feet from my computer to my xbox. It was a real eyesore! I always wanted a wireless adapter for my xbox, but really didn't want to pay the $100 pricetag. Anyway, I am very glad I did. It is worth every penny.

"works very well"
Firs' off people who think its too over priced i agree with you it must have taken $5 ta' make because its just an antennae. But its profits for microsoft so i understand. But it works perfect and works every were in my house so i would suggest this instead of and ethernet cable running through hallways and into your computer. so as being honest a possible i recommend this.

"Well it Works... DEFINITELY not worth the price"
First of all, I want to point out that I've used multiple devices to try and get a good connection between my WPN824 Netgear Router and my XBOX 360

Logitech Play Link - Works PERFECTLY, easiest to set up, online gaming is flawless but downloads were WAYYY too slow (hours and hours to download)

Netgear HDX101 Powerline Adapters - Didn't work at all, absolutely terrible performance, barely worked in the same room

Xbox 360 Wireless Adapter - The main reason for this review, it is the nicest looking of the ones I used/took up the least amount of space. However, I got it to stream HD off of my laptop. Even when the two were in the same room in clear view of the router, I never could get more than 2 out of 10 bars for the Media Center Performance test. I was frequenstly disconnected for NO reasons, yeah it worked but didn't do what I bought it for.

My solution? The Belkin Wireless Range Extender F5D7132. I picked it up used on Craigslist for 16 Dollars SHIPPED.
The setup was not the easiest, gotta follow the instruction in some amazon reviews if you use WEP security, but once it is set up it works AMAZING.
A. It extends your wireless, so now my router is on the other side of our 4,500 sq. ft house and on the first floor, this extender is on the 3rd floor in my room, extending the internet to my laptop.
B. You can hard-wire anything (XBOX 360) via ethernet into it's LAN port, making the connection to my laptop securely in the "Acceptable Range" for streaming HD. Now the XBOX is hard-wired, I have increased my wireless rnage significantly, and I paid 16 dollars.

Point being, SKIP THE MICROSOFT WIRELESS ADAPTER, pick up the Belkin Extender, does more, costs wayyyyyy less, WORKS!

"Simple Quick and Easy"
Had very little problems with this, took it out, clipped it onto the 360, plugged it in and ran the tests. It failed repeatedly on my NetGear wireless router until I discovered some of the services I had blocked on all attached devices were causing the issue. Unblocked the services (except for the kids PC's - lol) and I was in business connected to X-Box Live in no time. Looks like it belongs on the unit with the clip feature and I get a great signal even one floor down from the router.
