I would like to force 2.4GHz Wi-Fi on my MacBook Air because where I am currently everyone is on 5GHz and it has been clogged up so it’s really slow.

  • Do both networks have the same SSID?

You can't force it if your network has the same SSID for both bands. Apple has never provided a tool or even an API for doing this.

  • @DylanLarsen Unfortunately, no. Not from OS X on the built-in Wi-Fi interface. Use a third party Wi-Fi dongle or an alternative OS. Better yet, get the network admins to fix their network.
