i have a problem with IPAQ 610 and de association with the ssid.
The problem is: i have created two ssid one of them (SSID1) no past through the nac and the ipaq is associate but after 1 minute is disassociated and in the other ssid not even associatied. The ipaq is asoccieted to one of the ssid and take IP from the dhcp server but there no have conectivitie, i mean can't navegate with internet explorer and
The ipaq try to conect to AP 1010 and is a solucion with Wireless lan controller and NAC.
the two ssid, one of them no past through the nac(ssid1) and the ipaq asociet but in 1 minute is disassociated and in the other ssid (ssid2) not even asocieted.
This ocurr with this ipaq 610 and with ipod touch and all the movile device.
Take a look at the wlan session timeout and set that to a higher figure. If the ipaq and the other mobile devices connect, do they all function correctly until they get dissconnected from the AP. With NAC, devices will either need a client or the NAC will have to scan the devices. These device will not be able to pass the NAC unless you exempt these. Post your show run-config so we can see how you have your wlc configured.
