Step 1: Ensure your router supports a 2.4GHz Wi-Fi network (most dual-band routers support both 2.4 GHz and 5 GHz networks).
Step 2: Most 5GHz networks are suffixed by “_5G.” Select the network that does not have “_5G” in its name. Under your phone’s setting, set your Wi-Fi network to 2.4GHz
Step 3: Some 2.4GHz Wi-Fi networks are hidden. If you are experiencing difficulties finding your 2.4GHz networks, contact your internet service provider or router manufacturer for support.
