Introduction: Use Your Laptop As an Xbox/Xbox 360 "Wireless Adapter" on Windows XP/Vista, and Mac OSX
I hate how the Xbox 360's wireless adapter costs $100, so I looked online on how to use any adapter as one. I couldn't find an article on that, but found that you can use your laptop as a gateway, but many articles didn't work, the way they said to do it. I looked on Instructables to see if there were any how-to's about it, and there were none, so here is my second Instructable.
Things you need
CROSSOVER Ethernet cable (You can't use the one included with the xbox. But chances are that you have one lying around. Most will be labeled saying crossover. Thanks to sk8erek who reminded me to edit this.
I Edited this to show how to do it with Vista and Mac, so this will work for all 3. The one done by me is for Windows XP. Step 4 is Windows Vista. Step 5 is Mac OSX, both Leopard and Tiger
P.S.- This is new information. I just edited this on January 3, 2008. If you do this, you won't be able to connect to the internet through your Ethernet port anymore. Only providing internet will be possible. If you want to know how to fix this, scroll down to my comment about it.
EDIT: A fix for the above problem was posted in a comment by timheppner. I have not tried this myself, but he says it will work, so try it out.
"EDIT 2:" A guy named bsblade told me that my instructions on doing this on a mac were wrong, so I updated it according to his instuctable. To see changes, check out step 5
Step 1: Connect Your Ethernet Cable to Your Computer and Xbox
I know this doesn't sound like it should be the first step, but do it anyways. Trust me, It will work out in the end.
Step 2: Change Your Internet Properties
We have to change the internet properties so that your computer will share wireless internet with the Ethernet adapter. See pictures. They are in order as they should. They also have notes. After doing what all the pictures say, hit ok.
Step 3: Repair the Ethernet Connection
This is simple. Right click the Ethernet Cable icon in the task bar, and hit "Repair"
Pictures say it all.
Right click the non blurred icon. Then hit repair. It shouldn't have a red X though.
Step 4: On Vista
1. Go to start
3. Type in ncpa.cpl
4. Hit OK
Thanks for the help idogis1
Step 5: For Mac Users
