built-in wireless adapter

Hello.

If you have a Xbox 360 Slim (which as built-in wifi) and you are asked to attach an external networking adapter or an ethernet cable, then the internal wifi has malfunctioned and your Xbox 360 Slim will need to be repaired.

 

sorry self repair is not discussed on the forums, if your wi fi is not working on your 360 having MS repair it is your only true option.
