Hi Tas, Peter , James and thanks for your reply ,

I noticed that when the wireless user turned-off his wireless card the 
AP stores him/her Mac-Address for 10 minutes in a table (station table) 
and then dropped the Mac-Address. However freeradius continued to do 
accounting for this user over 2 hours. I read about the Idle - Timeout 
attribute but i don't know how to set it on. I authenticate my users 
from the local file users. Do you think my AP doesn't say nothing to 
freeradius after the mac-address drop? There is nothing in the AP 
web-configuration which could set it on and solve the problem. If the 
problem is the nas there is not a solution ?

Thanks a lot for your time....
