Most devices such as my door bell ,yale camera and cental heat salus run in 2.4ghz but doest the 3.0 operate on both 2.4 and 5 so they should connect ?
I am aware that some devices have problems connecting to the hub when smart wifi is turn on, so lets get it turned off.
Login into the hub at http://192.168.0.1 using the details from the base of the hub on a sticker.
When in goto "Advanced Settings", "Wireless", then "Wireless Signal", place a tick in circle where it says "Disable Channel Optimization" and then click on "Apply Changes".
That should solve your problem with connecting to the hub.
