The only problem is It cannot detect my network.
This comment leads me to believe that the mobo wifi is actually turned on and attempting to locate a signal. Is that the case?
If so, I would focus on your router. Often times, people set up a bunch of security (for good reasons) and it will interfere with a new device trying to connect; in some cases it deliberately hides signal, thus, preventing a connection. My advice is to turn off all security options on your router (like password restrictions, MAC lists, etc.) and make sure your router is broadcasting the SSID.
These are temporary measures but you want it to be as easy as possible for your new mobo to connect to the router. Once the connection is established, you can then turn on the security measures (one at a time).
Another thought - are you using Window's built in Wifi controller, or are you trying to use the mobo's? I've found that Window's controllers work well so try using it.
Hope this helps.
