Symptoms

Consider the following scenario:

  • You have set up a wireless (Wi-Fi) network profile that contains two or more service set identifiers (SSIDs) that are pushed to a Windows 8.1-based computer by using a Group Policy Object (GPO).

  • You connect the Windows 8.1-based computer to the Wi-Fi profile.

  • You put the computer into sleep mode, and then you wake up the computer after three minutes.


In this scenario, the Wi-Fi connection cannot be established.
