If I would have a setup where I have one or more devices on the 2.4GHz network and one or more devices on the 5GHz network, can they talk to each other if I'm using a ASUS RT-AC66U router?
For example if I have a Chromecast or Sonos system on the 2.4GHz network and connect my phones and laptops to the 5GHz network, will that work?
