Hi @jmf2022,
Your router will be broadcasting on both 2.4GHz and 5GHz, do you happen to know if the device that is working ok (the laptop) is connecting to one of those bands, and the devices that are not working are trying to connect to the other ?
As if this was the case it may indicate that you are suffering from Wi-Fi interference on one of those bands.
What model of router do you have ?
You could try changing the channels that your router broadcasts the Wi-Fi signal on, you can use free smartphone Apps like this to see what channels are being used within range of your smartphone, you can then change your router to use channels that are less congested.
I'm not sure what router you have, but be aware that the Sagemcom router has a feature called 'Wi-Fi Optimisation', this means it can change the Wi-Fi channel itself, overriding what you have set it to, it can randomly do this after minutes, hours or days !. So if you do find a channel that works well, but then things go bad again, check to see if the router has changed channel to something different to what you set it to. If you do experience this problem then just post back here to ask the staff to disable the 'Wi-Fi Optimisation' on your router, once that is done it will stay on whatever channel you set it to. This only affects the Sagemcom Wi-Fi Hub, if you have the Huawei Wi-Fi Hub it will stay on whatever channel you set it to.
The staff here probably won't be around now until Monday, but they should be able to respond to this post early next week to help.
