Thanks I will make as you have said…
 I try to make an analysis of what turns in the WLAN!
 Freeradius I have installed last version available (1.1.2 that it seems 
to work!) but I know that there is also an August version SNAPSHOT but 
to me it has given problems in compile and did not install me module 
EAP-TLS (bug Debian). 
The lib I have installed to them with the command apt-get install 
openssl libssl-dev and this is the command dphg - l|grep SSL
