Question : Problem: Wireless AAA

Hi, i'm really new in wireless field, even after i have read a lot of stuff regarding to wireless. I have configure Freeradius that run Radius protocol to authenticate my client, but my AP still could not talk with my Radius. I have used Freeradius as Radius server, Cisco AP340 as my NAS, or maybe someone could suggest other freeware linux base that could run Radius protocol.

Answer : Problem: Wireless AAA

That is extremely possible. When the wireless gets a request to connect to the lan, it passes the request to the radius server for authentication and once authenticated allows access to the lan. In this case, your debugging the requests coming to the radius server and it may not be replying properly.
