Hi, I will copy my reply here one more time, but we can just follow this issue on the other post:

Just to verify, when the iPhone 10 or Dell laptop tried to connect to the A7's 2.4GHz network, is there any error message when it cannot connect? If the Dell laptop connects to the network successfully, can I have the IP address/gateway it gets from the A7?

Try to change the 2.4GHz wireless security type to WPA2-PSK AES, save and reboot the router, then confirm the connection.

Try to enable the 2.4GHz Guest network and check if the Dell laptop and iPhone 10 can connect to it.
