You cannot configure a Wi-Fi Protected Setup device from a computer that is running Windows 7

Symptoms

When you try to connect the computer to a Wi-Fi Protected Setup (WPS) device, Windows 7 may not offer an option to configure the device. This offer is usually in the form of a wizard, a prompt, a button displayed on the desktop or sometimes a request for a PIN. Taking this action along with pushing a button on the external device will help the device connect to your computer or network. Without this interaction the connection may fail..

Cause

This issue occurs because Windows 7 does not follow the Wi-Fi Protected Setup (WPS) standard. The Wi-Fi Protected Setup specification version 1.0h of the Wi-Fi Alliance requires devices to ignore unrecognized attributes. A device that uses nonstandard attributes may send a message that contains an attribute that Windows 7 does not recognize. In this situation, Windows 7 does not ignore the unrecognized attribute that is present in the message that Windows 7 receives as expected. Therefore, an interoperability issue occurs and the device cannot be configured.

Resolution

To resolve this issue, click the link below for how to install Windows 7 Service Pack 1 (SP1):

Windows 7 file information note

Important Windows 7 and Windows Server 2008 R2 updates are included in the same packages.

  • The files that apply to a specific product, milestone (RTM, SPn), and service branch (LDR, GDR) can be identified by examining the file version numbers as shown in the following table:

    Version

    Product

    Milestone

    Service branch

    6.1.760
    0.16xxx

    Windows 7 and Windows Server 2008 R2

    RTM

    GDR

    6.1.760
    0.20xxx

    Windows 7 and Windows Server 2008 R2

    RTM

    LDR

  • GDR service branches contain only those fixes that are widely released to address widespread, critical issues. LDR service branches contain hotfixes in addition to widely released fixes.

  • The MANIFEST files (.manifest) that are installed for each environment are listed separately in the "Additional file information for Windows 7" section. MANIFEST files and the associated security catalog (.cat) files, are extremely important to maintain the state of the updated components. The security catalog files, for which the attributes are not listed, are signed with a Microsoft digital signature.
