    802.1x wireless RADIUS authentication stopped working - 6273 Audit Failure

    Hi,

    We use a combination of Ruckus and Network Policy Server running on 2008R2 to provide 802.1x authentication to our wireless network.

    For the past year, it has given us very few problems but now, nobody can connect. Always get the same "The RADIUS request did not match any configured connection request policy"

    We have very little in the way of network policies and connection request policies. Literally the only requirements are that they have wireless ability, are member of the Domain Computers group and use Windows authentication.

    The computers are logging on to the domain fine therefore it should be passing their AD credentials, they obviously have wireless and they are members of the Domain Computers group. The certificate hasn't expired.

    I have tried disabling all the policies and it still doesn't work. I have tried rebooting the NPS and the Ruckus box.

    Does anyone have any idea what is wrong? - here is the full log file :
