Default Tab Pro 8.4 connects to wifi on 2.4 and not 5, any way to get it to use 5?

I have a Netgear Knighthawk router and the main network is one name that utilizes both 2.4 and 5 and as long as the connecting device supports it, it should connect on that band.

My Nexus 5 and wife's S4 which are right next to my Tab are connected on the 5 band.

Any ideas on how I can force the Tab Pro to connect mm on 5?

Thanks
