Cisco 1130AG w/Radius

I am having a little trouble getting freeRADIUS to work on my Cisco 1130AG's. If someone has experience using these with their radius server, please respond with all the steps you have taken to have it work, e.g., where and what you put in IOS and on what pages. I for the life of me can not get it to work. I have tried for weeks. I appreciate ANY feedback and welcome all suggestions.
