Implementing 802.1x on Wireless Networks with Cisco and Microsoft

Server Setup

    Windows XP currently has the only available 802.1x client implementation available today, but there are other implementation in the works, including the open source Open1x, and another commercial implementation SecureSupplicant. These instructions assume that you're connecting with a windows 2000 server backend authentication, as setup in these instructions.

Step 1 - Get Client Certificate

Step 2 - Enable 802.1x authentication for wireless card

Step 3  - Enable Encryption (Optional - See notes on using dynamic WEP with Windows XP and Cisco APs)


Now you're ready to configure your Access Point, and authenticate via 802.1x.
