connectivity issues when using WPA2 Enterprise

[matantal.il]

hello everyone,

im using 3 AP's 1140 with local authentication using local radius (flex connect mode).

the radius server im using is MS 2008 R2.

authentication is working great on all devices pc's&mobile.

authentication method is PEAP wpa2 aes enterprise.

after 3 or 4 hours devices loose connectivity to the web.

the device seems to be still connected to the ap but there is no ping to host from local lan or any arp learnd on local router.

only manual disconnect on device and reconnecting brings connectivity up again.

in one case only reseting the AP's helped.

Well one thing to do is update the driver on the client device.  Also make sure you are only using WPA2.AES and not WPA TKIP.  Also maybe remove the session timeout on the WLAN and see if that helps.

Thanks,

Scott

thanks Scott ill check the settings you mentionedint the first post.

anyway the bug described is not the same .

The ap is not crashing its ap other devices still connected but random devices get "stuck" from time to time.

mostly mobile.

I will update thanks.

Well the AP crashes internally:)  So if you search the forums, search for "1142 v7.4", you will find others that had to reboot the AP to fix it almost once a day.

Thanks,

Scott
