Hi ChinyQ,
Thank you for posting your question.
Who is the manufacturer of the Network Adapter?
Make sure that you have installed the Network Drivers for the Adapter.
Most of the windows wireless settings are held in the systems registry:
HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Wireless (Should hold what you need)
Take a Cleanly setup machine, configure the wireless, and export that key.
You should be able to merge those details with the registry of another machine (perhaps restart) and it should have the details required to connect.

DISCLAIMER: Before you edit the registry, export the keys in the registry that you plan to edit, or back up the whole registry. If a problem occurs, you can then follow the steps in the "Restore the registry" section to restore the registry to its previous state. To back up the whole registry, use the Backup utility to back up the system state. The system state includes the registry, the COM+ Class Registration Database, and your boot files.
