My wifi was split previously into 2.4Ghz and 5Ghz settings which worked better for me as I have a number of devices connected. Lately the wifi went down so I reset it and now it won't split between 2.4 and 5Ghz again. I have been to my Hub 3.0 settings page and it says there that they're both turned on but only the standard one is appearing as something I can connect to.
Access your Hub by navigating to 192.168.0.1
Login with the default login info (on base of Hub) unless you've already updated it.
Go to Advanced Settings > Wireless > Security
Under Wireless Frequency 2.4GHz change the Wifi Network Name (SSID) and the Wifi password (network key).
Repeat for the Wireless Frequency 5GHz and click on Apply changes.*
*Make sure that both frequencies are named differently and are still identifiable (adding 2.4 and 5 to the end of each should suffice).
