Iphone 16 does not see the Wi-Fi 5 GHz network

If the issue is:

• that your iPhone does not see the 5GHz version of two separate networks: 5GHz is a technology that allows more bandwidth at the cost of less area effectively covered. Maybe you are out of reach? Also: try resetting network settings on your phone, or check the settings of your router. More potentially useful info in this thread: iPhone 16 Pro Not Detecting 5GHz Wi-Fi Ne… - Apple Community
