Invalid Encryption Combination - Downgrade WPA2 to WPA

I'm trying to set up this 7210 Mobility Controller and I have an existing SSID and it works fine but for backwards compatibility reasons I need to change the security from wpa2-aes to wpa-tkip (I realize this is not recommended for security reasons).  However when I uncheck the wpa2-aes checkbox and then check the wpa-tkip checkbox and then hit Apply I get the error pop up "Invalid Encryption combination".  See screenshot below.  Any ideas on how to get passed this error?  Thanks.

Try this:

 

config t
wlan ssid-profile <your ssid profile>
opmode wpa2-aes wpa-tkip

Thanks, yes it seems I must have wpa2-aes also checked.  There is no way to only have wpa-tkip checked, thanks!
