You cannot log in windows 7 with domain user because wireless is not connected on logon screen. This feature is available only on Windows 8, 8.1, 10.
Workaround:
1. Open REGEDIT HKLM\Software\Microsoft\Windows\CurrentVersion\Run
2. Add new string value with any name you like. For example WiFiAutoconnect
3. Set value: %comspec% /c netsh wlan connect name="MyWiFi" where MyWiFi is your wireless profile name.
