Open a browser and log into your hub 192.168.0.1 - then navigate to the following settings so you can differentiate between the signals.
Advanced Settings > Wireless Signal > click on Disable Channel Optimization then scroll down and click on Apply Changes.
Now go to Advanced Settings > Wireless > Security > Add a 2 to the end of the 2.4GHz Channel name, then further down add a 5 to the 5 GHz Channel name and click on Apply Changes.
You can leave the passwords the same as they are. Then log out of the hub at the top of the page
You will need to reconnect all you Wi-Fi devices some will want to connect to 5Ghz and some to 2.4GHz and some will connect to either.
You could also do a search for an app such as wifi analyzer which tells you the strength of the channel you are connected on, and also shows other channels so you can decide if you want to change the channel number on your hub
Advanced Settings > Wireless > Wireless Signal > beneath both the 5Ghz and 2.4GHz sections click on the manual button, and in the drop down box click on the channel number you want to change it to, then scroll down and click on Apply Changes
