I am looking for some configuration guidelines, discussion, or a whitepaper to convert my Cisco ap's from WEP with 128bit keys over to WPA or something better. Is WPA the way to go at this point? I am concerned on how to convert my current wireless over which has about 50 access points spread out across the country. Currently, we use the same wep key thoughout the organization. How would I do this with minimal downtime toward the users. How much configuration would there be? I am using Cisco 1200's and 1242ag wap's currently. They are all standalone configs.
