I typically see this issue when the wlan has multiple encryption types. For example, if you had WPA/TKIP and WPA2/AES together or a mix or all configured. You want to specify just one or the other and also be aware if you initially had the wlan broadcasted and the disabled.  Try removing the profile from the client and configure it again.
