this guide will show you how to hard wire an internal wifi adapter to your original xbox. you dont need a high level of soldering skills for this modification. i will be going through the tools and steps i personally used and did to get it working, you may find other suitable choices from what i have done. most of the stuff can be applied to different methods as we are just soldering directly to the pinouts of the ethernet port and 5v/ground from the psu.
please read part preparations to determine if you will need or would like any of the optional features.
