RADIUS and ap client with router behind ..

Hello all

I'm preparing to change security in my WLAN to some better one. I have Linux server so it's not a problem to make RADIUS server.

Which auth is the best ? Will I have a problem with AP clients or some subnets behind ap clients and router ? Do You know some web pages where I can get a deep discription of 802.11 security features ?
