I've a Aironet1200 with 802.1x (Cisco Secury ACS) integrated with Active Directory and in a ray of 15 meters of reach my Laptop lost the connection. The most curiosity is that I get looking for the connection status screen and on the exact moment when I lost conection the signal was between 90%~100%. With the Network Stumbler I saw that the channel was not congestioned. Have somebody here that have been the same problem and has solved that?
when the client is connected do a show dot11 ass all on your ap.. and watch yuor SNR and signal strength readings. just to take a look towards interference. But also ensure your drivers are up to date and the latest.
