in my customer office using only Wifi network using Aironet 1240AG, only 3 PCs getting issue it include one of my office PC. seem the session is terminated but wifi status is connection normally, when i see on the AP log it show as " Interface Dot11Radio0, Deauthenticating Station 7018.8bf7.15e1 Reason: Sending station has left the BSS "

after disconnected wifi network and reconnect on PC, it working  around 5 or 10min depend on situation

What version of IOS you are running on this ? Try the latest (c1240-k9w7-tar.124-25d.JA2.tar) & see if that helps.

Also attach your AP config (show run output)  to see how you configure it

Dear Rasika,

we wonder why all other 20 pcs can connect to AP as normal except only 3 stations. that can't connect. we don't have account to download it do you have any available image for latest version? please advise.
