The Xbox is made by Microsoft
The first XBOX has a (Cat) LAN Connection and a wireless addon. The first XBOX 360 has a (Cat) LAN Connection and a wireless addon. The first XBOX SLIM has a (Cat) LAN Connection and built-in wireless.
I don't know when but Microsoft built the XBox 360
The Classic Xbox and the Xbox 360 are the only two consoles from microsoft. The Classic Xbox was first released on November 15, 2001 in North America and then The Xbox 360 was officially unveiled on MTV on May 12, 2005.
Only the Xbox 360 S has built-in wifi.

The xbox Elite does NOT have built in wifi. Only the xbox 360 slim has wifi built in, it is the newest xbox out. the elite needs a wifi adapter which costs 100$, the arcade, pro and elite dont have built in wifi, just the slim, which came out just a few months ago.
Yea
To my knowledge you cannot connect your xbox w/built in wifi to a dsl connection without a wifi converter
First of all, do you have the Kinect. The Kinect has a built in microphone so you can command your xbox with voice. I have an xbox 360 (slim 250 GB) and a Kinect but I don't think you can switch it on by voice.
