This network employs a technology called captive portal which allows the administrator(s) to restrict network access to trusted users. In order to prevent certificate security warnings when accessing this portal, the network's filtering unit must issue to your computer or mobile device a file called an SSL certificate.
This guide will help you install the SSL filtering certificate for Windows-based browsers which use the operating system's built-in certificate store — this includes Internet Explorer, Chrome, and Safari.
First, click the Download Certificate button below; this will begin a download of the file to your computer.
Depending on your browser and configuration, you will probably be asked whether you would like to open the file or save it; choose Open. Depending on your browser, you may then have to click Open a second time.
(Note: These images show Internet Explorer 10 running on Windows 8; you may not see exactly the same thing if you are using another browser or a different version of Windows; however, the general process and wording should be the same.)
Depending on your browser and configuration, you may see a Security Warning which asks if you're sure you want to open the file; if so, click Open once more.
Next, you will be presented with a Certificate dialogue. Click the Install Certificate... button near the bottom of this window.
The Certificate Import Wizard will open next. Depending on your configuration, you may be asked whether to install for the Current User or the Local Machine; if asked, you should normally select Current User. In either case, click Next.
The next screen will ask whether you would like to have Windows automatically select a certificate store or you would like to select it yourself. Opt to select yourself, by clicking on Place all certificates in the following store. Then, press the Browse button to the right.
The Select Certificate Store dialogue will open. Highlight Trusted Root Certification Authorities in the list, and then press OK at the bottom.
Back at the main wizard screen, the Certificate store box should now show Trusted Root Certification Authorities. Press Next again.
At the Completing the Certificate Import Wizard screen, press the Finish button.
A Security Warning will appear, asking if you're sure you'd like to install the certificate. Click the Yes button.
A confirmation will appear, indicating that the certificate import was successful. Press OK.
You're done! You may close any remaining certificate windows and continue browsing as usual; in most cases, you will not notice anything different after the certificate is installed.
