891fw Wireless Band Preference

I have an 891fw.  I have both radios working on a single SSID, the problem is that my client devices join the 2.4 Ghz radio by default.  If I shutdown the 2.4 Ghz interface, the devices will join the 5 Ghz radio.  How do I set the 5 Ghz radio as the "default?  I've posted the AP config below.  Thanks in advance.

The wireless NIC card makes

The wireless NIC card makes that decision. 

 

In some wireless NIC card, you can actually choose which radio to prioritize or use first.
