I rebooted the almond, and also put it back to factory settings and set it up over again. I also tried 'forgetting' the wifi connection on the iphones and then re-establishing it. I also tried changing the 5GHz channel to 40 which I saw on an apple forum. The weird part is that the iphones are showing that they are connected, and they appear to be functioning fine on the wifi. But they won't show up in the almond 3 devices list. And that is my issue. I want to control the kids wifi usage on their iphones, and if they don't show in almond 3 then I can't use the parental controls feature.
The 2 Alexas, 4 Belkin wemos, and a Nintendo are all using the wifi also, and they don't show on the almond 3 either, but the iphones are my main priority. Even stranger, 3 laptops and 3 tablets do show on the almond3, so it appears to be working. But something is not right with the iphones. (a 7, a 6, and two 5s).
