Not sure, you'll need to do some research. To start you'll need to build winpe with wireless support enabled. According to Microsoft there is WinPE Wifi Package, but there is also a note that says Windows PE doesn't support general wireless networking functions, whatever that means?
Network/WinPE-WiFi-Package WinPE-WiFi-Package is used by Windows Recovery Environment (Windows RE) for built-in recovery functions. This package is included in the base winre.wim file.
Note: Windows PE and Windows RE don't support general wireless networking functions.
