If you're looking to set up your Airport Extreme to operate in 5GHz mode, you're probably doing so to avoid interference from other devices operating on the 2.4GHz band, like your microwave or cordless phone. To set up your Airport Extreme to operate in 5GHz mode, you'll need to open the Airport Utility on your device and click on Manual Setup. From there, you'll be able to select the 5GHz mode option. It's important to note that the 5GHz band doesn't travel as well through walls and other obstacles, so you may experience a drop in connection in certain areas of your home. Additionally, some older devices may only be compatible with the 2.4GHz band.

What You'll Learn

Using Airport Utility to set up 5GHz
To set up a 5GHz network with your AirPort base station, start by opening the AirPort Utility application on your Mac. You can find it in the Utilities folder within the Applications folder.
Once the application is open, you will see a graphical overview of all the base stations available. From there, select the base station you want to configure and click on "Edit". Depending on your setup, you may be asked to enter a password for the base station. After that, click on "Wireless" and then on the "Wireless Options" button near the bottom of the pane.
In the new window, select the "5GHz" checkbox. Now, you can enter a name for your new 5GHz network in the "5GHz network name" field. It is recommended to use a name that easily distinguishes it from the primary network. After that, select your country from the "Country" menu and click "Save". Finally, click "Update" to apply the changes. Your AirPort will now restart, and once it starts back up, you will be able to see and connect to the new 5GHz wireless network.
Note that the 2.4GHz and 5GHz networks are always on, and they are bridged, meaning they are the same logical network. Devices connected at 2.4GHz can see devices connected at 5GHz and vice versa. By default, the SSID given to the 5GHz network is the existing one plus "5GHz" (e.g. "WLAN"/"WLAN 5GHz"), making it a separate network by default.

Manually selecting the 5GHz band
It is important to note that the 5GHz band has a shorter range and does not travel as well through walls and other obstacles as the 2.4GHz band. As such, it is recommended to keep the two bands together to allow the Airport Extreme to automatically negotiate the best possible speed for your device based on signal strength and other factors.
If you still wish to manually select the 5GHz band, you can do so by creating two separate wireless networks: one for the 2.4GHz band and the other for the 5GHz band. This will give you more flexibility in choosing which band each device connects to. However, having separate networks may result in lowered speeds and some older devices may only be compatible with the 2.4GHz band.
Additionally, when activating the 5GHz band on the Airport Extreme, a separate network with the default SSID will be created, which can be renamed. This will allow you to connect your wireless clients to the 5GHz network.

Creating two wireless networks
The Airport Extreme from Apple allows you to configure the 2.4GHz and 5GHz bands in two ways. The first is to give both bands the same name, allowing devices to find the highest band on which they can operate. The second is to give them two distinct names so you can choose the band on which you want each device to function.
To create two wireless networks, you will need to configure your AirPort base station. This will allow you to have one network for the 2.4GHz band and another for the 5GHz band.
- Open the AirPort Utility application. It can be found in Applications -> Utilities.
- Click on the AirPort Extreme icon and select Edit.
- Click on the Wireless tab in the settings window.
- Click on Wireless Options.
- Select the 5GHz checkbox.
- Create a name for the new 5GHz network in the 5GHz network name field. Make sure the name is distinct from the primary network.
- Select your country from the Country menu.
- Click Save and then click Update.
- The AirPort will restart to apply the changes. Once it restarts, you will see the new 5GHz wireless network.
Note that you can also change the name of the 2.4GHz band if you want to. To save the changes, click Update.

The drawbacks of the 5GHz band
The 5GHz band has some drawbacks that are worth considering when setting up your Airport Extreme. Firstly, it has a shorter range than the 2.4GHz band. This means that you need to be closer to your router to take advantage of the higher speeds that 5GHz offers. If you are too far from the router, your connection may be unstable or drop altogether. This can be mitigated by using a WiFi extender or moving your devices closer to the router.
Another drawback of the 5GHz band is that it does not penetrate walls and solid objects as well as the 2.4GHz band. This is because higher frequencies have more difficulty passing through solid objects. As a result, you may experience a weaker signal or dead spots in certain areas of your home or office when using the 5GHz band.
Additionally, not all devices are compatible with the 5GHz band. Older devices, in particular, may only support 2.4GHz. This means that if you have a mix of old and new devices, you will need to use both bands simultaneously, which can be more complicated to set up.
Finally, the 5GHz band is more susceptible to weather conditions and interference from other wireless networks. This can result in a less stable connection, especially if you live in a densely populated area with many nearby wireless networks.

Dual-band mode
To set up dual-band mode on your Airport Extreme router, follow these steps:
- Open Airport Utility on your computer.
- Click on the icon of your Airport Extreme router.
- Click on the Wireless tab.
- Change to a short name with no spaces and use only alphanumeric characters.
- Click on the Wireless Options.
- Give the 5 GHz network its own name. This will create two separate networks, one for each band.
- (Optional) Change the name of the 2.4 GHz band if you want to.
- Click Update for the changes to be saved.
Note that some older devices may have difficulty connecting to a simultaneous dual-band wireless network signal. In this case, you can try turning off the 5 GHz network on your Airport Extreme router or using a separate router for the 2.4 GHz signal.

Frequently asked questions
Open Airport Utility, choose Manual Setup, click the Wireless tab, then Wireless Network Options. Here you can give the 5 GHz network its own name. This will create two separate networks, one for each band.
The 5GHz band is much less congested, so if you have devices that support 5GHz, they will perform better on this band.
Yes, Airport base stations released after 2009 are capable of operating over both 2.4GHz and 5GHz bands at the same time. The Airport Extreme allows you to choose two ways to configure the bands: with a single name for both bands or with two distinct names.
The 5 GHz band doesn't have the same reach as 2.4GHz and doesn't travel as well through walls and other obstacles.
