A supplicant (external link) is an application that allows a computer to submit its identifying & security credentials to a secure network (external link) so that the server may authenticate the supplicating computer and grant it access. While most wireless card drivers will recognize the standard security protocols the authenticator will request, in some cases certain drivers may use a newer or proprietary supplicant that, while similar enough to the network's to allow access, may cause serious connection problems later. For this reason, after you download a driver update directly from your computer's manufacturer's (or from your card set vendor's) website, you should open your IllinoisNet Properties window and check its security settings. To do this:

  1. Left-click the Internet icon in the lower-left of your Taskbar. All available Wi-Fi networks should pop-up in a menu.

  5. Reboot your computer.
