I have a problem setting up the wireless connection on my XBOX 360 without using the original XBOX wireless network adapter. I just plug an extra wireless AP to the XBOX. System registered as a wired network connection but failed when it is checking for the IP address. My current network at my place is secured with password and i dont know how to access the ASDL router via XBOX.

Please help guys!!

Which means the only option i have is to buy the MS wireless network adapter to go wireless networking?
I saw a thread mentioning alternative wireless connection using wireless AP.
Again im in a secured network connection
