How To Change the 2.4GHz and 5GHz Channels in AirPort

Open the AirPort Utility app on your Mac. If you have one of Apple’s AirPort routers, you can use the AirPort Utility app to set which band your router broadcasts. The AirPort router normally switches automatically between bands, but you can override the Automatic setting so it only broadcasts one band. That way, you’ll always know which band your iPhone is connected to. To find the app, open the Applications folder on your Mac, then open the Utilities folder and double click the AirPort Utility icon.

Select the base station you want to edit in the graphical overview. When you open AirPort Utility, you should see an image displaying your router and any other devices connected to it. Click on the image of the router you’d like to make changes to.

Click Edit. When you click on the router, a window will pop up displaying information about it. Click the Edit button in the lower right corner.

At this point, you might be prompted to enter the password for your router.

Select Wireless. When the Edit menu pops up, click Wireless.

Open Wireless Options. Look near the bottom of the window for the Wireless Options button, then click on it.

Choose the channel you want your devices to connect to. A dialog box will appear displaying the wireless configuration options. Look for a dropdown Channel menu and select the band you prefer to connect to (either 2.4GHz or 5GHz).

Tap Save. Once you’ve selected your preferred channel setting, click the Save button. This will close the Wireless Options dialog box.

Click Update. This will apply the changes to your router settings. Your iPhone and any other devices on the network will now connect to whichever band you selected.
