This question is asked often.  Here is a cut and paste from my webpage.

Method 2, Internet Connection Sharing

   1. Connect your Xbox360 to the ethernet port on the back of your computer.

   2. on your computer, hold the windows key and press R (The windows key is the key with a windows logo on it, typically found between the left ctrl and alt keys by the spacebar. On laptops the location can vary)

   3. A 'run prompt' will open. Type ncpa.cpl and press enter. This opens up a window called 'network connections'

   4. If you have a network bridge or sharing in place already, remove it.

   5. Right click on the wireless connection, click properties, then click the sharing tab on top.

   6. Check the box that says "Allow others to connect using this connection. Click ok.

   7. Windows will do it's thing for a few seconds and then it may inform you of your ethernet port's new IP address. Take note of this, Specifically the 3rd number. It will likely be '192.168.0.1', but it may be '192.168.1.1' depending on your network settings. If it is 192.168.1.1, then replace the 0 in steps below with a 1 for IP, Gateway, and DNS settings

   8. On your 360, go to network settings. set to manual. enter the following info.

      IP Address= 192.168.0.2

      Subnet Mask= 255.255.255.0

      Gateway Address= 192.168.0.1

      DNS for first server put 192.168.0.1 Leave second blank.

      When you test your Xbox live connection after entering the first 3 IP numbers, your DNS may automatically set to the correct one. You can leave it auto in this case, or set it to manual to avoid any future issues.
