The Main Reason I Bought It:
I got tired of unhooking the router so I could play online when using my Xbox 360. My family also got tired of it as they wanted to get online also with the router. Instead of taking turns I finally got the Xbox 360 Network Adaptar. The 360 Network Adapter is much easier to deal with compared to using my router because I would have to keep adjusting the antenna on the router once hooked up to my 360 until I got a connection. Adjusting the antenna until getting connected could take a long time.
Its Connection Speed:
As far as caparison to using my router and the 360 Network Adapter to get on Xbox Live I can connect faster with the xbox 360 network adapter and don't have to deal with the hassle of unhooking my router. Whats even better about the 360 Network Adapter is I usually automatically connect to Xbox Live once I turn the console on.
The only complaint that I would have would be getting everything installed right when trying to set up the 360 Network Adapter. This complaint is very minor though.
The purchase was well worth it and is less hassle than before.
