How do I change my Wi-Fi speed to 2.4 g on my iPhone 13 Pro MAX?

Could you explain your situation and requirements in a little more detail?

2.4 GHz is a band, with various channels, and various different Wi-Fi network speeds are available within that band.

Which Wi-Fi band and which channels within the band you can and will connect to (2.4 GHz, 5 GHz, and 6 GHz) depends on your Wi-Fi hardware and your hardware configuration, and depends on your physical location.

Your Wi-Fi router will offer an SSID Wi-Fi network name, and your Wi-Fi client will connect to the client-accessible channels available with that SSID on whichever bands are available on both the Wi-Fi client and the Wi-Fi router.

One Wi-Fi network can offer one channel in one band, or many channels across the available bands.

If you need to require a channel in 2.4 GHz, then you’ll likely need to reconfigure the router to offer a SSID for that channel or channels.

2.4 GHz wouldn’t be my usual choice generally, as that band tends to have more interference than does 5 GHz or 6 GHz.

*Apple isn’t offering Wi-Fi 6E and 6 GHz quite yet.

I will check my router - I am trying to sync some light bulbs and they do not work with 5 g . Thank You for the prompt response and Merry Christmas!

So long as your Wi-Fi router network name (SSID) is configured for and broadcasting at least one 2.4 GHz channel, the Wi-Fi should be compatible with these 2.4 GHz devices.

That is controlled by the router it is connected to. If your router has two frequencies it will usually have two SSIDs or a menu choice.

Do you have a dual frequency router?

Did you bond the 2.4 and 5 Ghz into a single network connection?

Are you having connection issues?
