Adding 2.4 ghz Wi-Fi plug…splitting 2.4 from 5 ghz

[minnieha_ha]

Hi, I’m having some problems adding a Wi-Fi smart plug. I (think) I have split the channels, and that’s what it confirms on the router home page. However, when I turn off 5ghz to add the smart plug to the hub, the app, and I have tried a few, on my device (iPhone) seems to think it’s still connected to 5g. 5g is not showing in my iphone settings. I’m getting sincerely ticked off. 
in case you’re wondering, I have four plugs, they can’t all be faulty, and why is my app showing connected to 5g. Attached image to show disabled 5g.

hhheeeeellllppp!!!!! 🙂

Have you tried rebooting your iPhone?
