Wireless - Common Certificate Errors on Windows

This article provides information regarding the expected certificate error(s) on Windows machines.

On Windows devices, your machine will fail to connect initially and will give you the error message "The connection attempt could not be completed". This displays when your machine notices the network certificate has changed in the authentication process. This error message appears whether you use XpressConnect profiles or not.

The workaround is to click Connect to dismiss the initial warning to get connected. Once you have a network connection, you should install an updated XpressConnect profile from https://wireless-ucsecure.uchicago.edu. This will ensure your machine gets the updated intermediate CA certificates with the right trust settings.
