Thanks once again.
Sorry for being cheeky but I do have some apple airport devices that I could connect and I know I can split the channels on those. Will there be any conflicts on the network if I use this to connect my 2.4GHz devices.
Short answer is... I dont know 😎
I have two Expresses on my network - but my Hub is in modem mode with an Airport Extreme doing the routing. The 2 bands are separated in the Extreme and the Expresses simply extend both bands - and I can select which band to connect to on each device.
So I am guessing it wont allow splitting bands downstream of a Hub which has a "combined" SSID in router mode (hope that makes sense !)
But why not do the experiment and see if it works for you?
