iPhone 14 pro will connect to 5mhz but not 2.4 mhz router

Your phone automatically looks for the best combination of speed, low noise, and lack of interference. It chose the 5 GHz connection for that reason.

2.4 GHz signals are slower, and typically pick up more interference simply because there are a lot more 2.4 Hz networks than 5 GHz. The only advantage to 2.4 GHz is that the signals are a bit stronger, and penetrate walls and other obstructions more effectively than 5 GHz.

Check your Wi-Fi router to see if it has an option to assign a different wireless network name to each of the 2.4 GHz and 5 GHz broadcasts. Then, you can "point" your iPhone at the specific network that you want, even though it might not be the best network to use.
