Manually Configuring your Windows Laptop for the AddTrust External CA Root Certificate
Issues with user laptops not being able to connect to wireless due to CA issues.
Note: This article is intended for Windows machines that are already configured for UI Wireless access.
In addition, this article assumes the AddTrust External CA Root certificate is already installed on your laptop. Most Windows laptops that are updated regularly will have already obtained the AddTrust External CA Root certificate through Windows Updates. If you do not see the AddTrust External CA Root certificate (step 4 for 7/Vista), run all Windows Updates on your computer.
Alternatively, see article 2029 for information on manually downloading and installing the root certificate on your Windows laptop.
