How to fix validating identity
While the modem seems to be operating properly, on her laptop, the only computer she has, running Windows XP, when connecting to the wireless network, at the bottom of the screen, I get an [endless] message, Windows was unable to find a certificate to log you onto the **** network.
At the top of the screen, where it says, Choose a wireless network, I get an [endless] Validating identity.
Also, make sure that you are using WPA(2) Personal (PSK) for both the Comcast gateway, and for the Wi Fi client that you are setting up; don't try to use "WPA-Enterprise" or "802.1X" security because that almost certainly will require resources that you don't have (resources such as a security certificate for that connection).
The following steps explain how to force the Access Gateway to re-import the metadata of the Identity Server.In a few simple steps you can bypass Windows Validation, and the resulting “Limited or No Connectivity” issue on an encrypted connection.The Identity Server is the identity provider for other Access Manager components. When a device is imported into the Administration Console and an Identity Server configuration is selected for them, a trusted relationship is established with the Identity Server by using test certificates.It says something about windows not finding a certificate.
The weird part is that I was using WPA TKIP with the passphrase and it was working fine.
I thought that at first, perhaps, a virus and/or malware somehow got by and changed/altered the wireless settings, though the antivirus software and Malwarebytes software is up-to-date and is showing no problems. One of these may be doing strange things with the connection. If that does not work it could be a newtork card driver issue. However, before you do that I would advise you to make sure that you have the driver disc for that netcard (or for the notebook if it is an internal Wi Fi netcard), because Windows will often not have built-in drivers for any given netcard.
