If you want to split your Wi-Fi network, instructions on how to do that are in link below, when you have selected Advanced Settings you will also need to select Wireless, Wireless Signal and click on Disable Channel Optimization at the bottom then click on Apply Changes.

If you are using Virgin's Wi-Fi pods don't split your network.
Virgins Wi-Fi pods require the hub's Channel Optimization to be enabled.
