Apple's Airport Extreme is a dual-band router that can broadcast both 2.4 GHz and 5 GHz signals simultaneously. This allows devices to connect at either frequency, depending on their capabilities and the wireless technology they use. While older devices may have trouble connecting to the 5 GHz band, it is less congested and offers higher speeds, making it ideal for newer devices. The 2.4 GHz band, on the other hand, is more crowded and slower but is compatible with a wider range of devices, including some older technology.
| Characteristics | Values |

| GHz | 2.4 GHz and 5 GHz |
| Dual-band | Yes |
| Performance | Inconsistent speeds between 2.4 GHz and 5 GHz |
| Congestion | 5 GHz band is less congested |
| Range | 5 GHz has more difficulty transitioning through walls |

Airport Extreme's 2.4GHz and 5GHz bands
Apple's Airport Extreme router allows users to broadcast both a 2.4 GHz and a 5 GHz signal simultaneously. The 2.4 GHz band is compatible with older devices but is slower and more congested, while the 5 GHz band offers higher speeds but may have more difficulty transitioning through walls.
By default, the Airport Extreme uses the same wireless network name for both bands, allowing devices to connect to the highest band they support. However, users can also choose to give each band a unique name, providing more control over which band specific devices use. This can be done through the Airport Utility application.
To separate the bands, users can open Airport Utility, click on the Airport Extreme icon, and select "Edit". Clicking on the “Wireless” tab will display the network name. Clicking on the “Wireless Options” button will allow users to check the box for the 5 GHz network name, creating a separate name for that band.
It is important to note that while giving the 5 GHz band a different name can help manage congestion, it may also reduce signal strength, especially when trying to connect from another room. Additionally, some older devices may only support 2.4 GHz, so it is essential to check device compatibility before making any changes.

How to set up Airport Extreme to 5GHz
By default, Apple's Airport Extreme router broadcasts both a 2.4 GHz and a 5 GHz signal using the same wireless network name for both bands. This allows devices to connect at 2.4 GHz or 5 GHz based on their capabilities. However, older technology devices may have trouble connecting to this type of simultaneous dual-band wireless network signal.
To set up your Airport Extreme to 5GHz, follow these steps:
- Launch the Airport Utility.
- Click on the Airport Extreme icon and select 'Edit'.
- Click on the 'Wireless' tab. You will see the name of your network in the 'Wireless Network Name' field.
- Click on the 'Wireless Options' button.
- Check the box labelled '5GHz network name'. This will append 5GHz to the existing name, or you can enter a new name.
- Click 'Save' and then 'Update'. The Airport Extreme will restart.
- After the restart, the 2.4GHz network will have the original network name, and the 5GHz network will have the new name you entered in step 5.
You can also use an app called iStumbler to see all the networks around you and their respective channels. This can help you pick a less congested channel for your 5GHz network.
Note that some older devices may only support 2.4 GHz. You can choose to give both bands the same name, allowing devices to connect to the highest band they can support, or you can give them distinct names to actively choose the band for each device.

Devices that only support 2.4GHz
Many devices use the 2.4 GHz frequency, including microwaves, baby monitors, security cameras, garage door openers, wireless microphones, wireless speakers, and video cameras. Household telephone wireless handsets also use the 2.4 GHz spectrum in the UK.
Some older devices may have trouble connecting to dual-band networks that broadcast both 2.4 GHz and 5 GHz frequencies, even if they are new products. For example, an OUCAM camera can only work with 2.4 GHz Wi-Fi but may not be able to connect to a dual-band network if it defaults to the 5 GHz frequency. Similarly, some older wireless cameras may have trouble connecting to dual-band networks due to interference from other devices operating in the same 2.4 GHz band.
To ensure that a device connects to the 2.4 GHz frequency on a dual-band network, you can give the 2.4 GHz and 5 GHz frequencies different network names. This allows you to manually select the 2.4 GHz network for devices that are unable to connect to the 5 GHz frequency. Alternatively, you can turn off the 5 GHz network on your router, forcing all devices to connect to the 2.4 GHz frequency.
It is worth noting that the 2.4 GHz frequency has a longer range and can penetrate solid objects more easily than the 5 GHz frequency. Therefore, it is better suited for devices that move around a lot or are used further away from the router, such as smartphones in larger homes.

Issues with inconsistent speeds between 2.4GHz and 5GHz
Apple's Airport Extreme is a dual-band router, meaning it can broadcast both a 2.4 GHz and a 5 GHz signal simultaneously. While the 5GHz band typically offers faster speeds, some users have reported inconsistent performance between the two bands, with the 2.4GHz band occasionally experiencing slow speeds.
There are several factors that can contribute to inconsistent speeds between the 2.4GHz and 5GHz bands on an Airport Extreme router:
- Network Congestion: The 2.4GHz band is more susceptible to network congestion due to the prevalence of other devices operating in this frequency range, such as household phones and Bluetooth devices. Switching to the 5GHz band can help alleviate this issue as fewer nearby networks use this frequency.
- Distance from Router: The 2.4GHz band typically offers a superior range compared to 5GHz. As a result, the WiFi speed on the 5GHz band may drop off more quickly as you move farther away from the router.
- Device Compatibility: Older devices may have difficulty connecting to the 5GHz band and may be limited to the 2.4GHz band. This can impact overall network performance, especially if the older devices are not compatible with the newer wireless standards used by the 5GHz band.
- Channel Selection: The choice of WiFi channel within the 2.4GHz band can also impact performance. Many routers default to Channel 11, which can lead to congestion if multiple nearby routers are using the same channel. Changing the channel to a less crowded one can help improve speeds on the 2.4GHz band.
To troubleshoot inconsistent speeds between the 2.4GHz and 5GHz bands on an Airport Extreme router, users can try the following:
- Use an app like iStumbler to identify less crowded WiFi channels in their area and switch their 2.4GHz channel accordingly.
- Ensure that their devices are compatible with the 5GHz band and update device drivers if necessary.
- Move their router to a more central location to improve signal strength and reduce the impact of distance on the 5GHz band's performance.
- If issues persist with specific older devices, try turning off the 5GHz network on the Airport Extreme router to force it to use only the 2.4GHz band.

Using Airport Utility to configure bands
Apple's Airport Extreme is a dual-band router, which means it can broadcast both a 2.4 GHz and a 5 GHz signal at the same time. The 2.4 GHz band has a wider range but is more congested and slower than the 5 GHz band, which has less interference and faster speeds.
To configure your bands using Airport Utility, follow these steps:
- Launch the Airport Utility app on your iOS device.
- Click on the Airport Extreme icon and select 'Edit'.
- Navigate to the Wireless' tab, where you will see your network name in the 'Wireless Network Name' field.
- Click on the Wireless Options' button.
- Here, you will see options to configure your 2.4 GHz and 5 GHz bands. You can choose to give them separate names or use the same name for both bands.
- If you want to give the 5 GHz band a separate name, check the box labelled '5 GHz network name' and enter a new name. This will give you two separate networks with different names, allowing you to choose which band your devices connect to.
- Click 'Save' and then 'Update'. Your Airport Extreme will restart with the new settings.
By default, newer Airport Extreme routers will broadcast both bands with the same network name. Most modern devices will connect to the appropriate band based on their capabilities. However, some older devices may have trouble connecting to the 5 GHz band, in which case you can follow the above steps to create separate network names for each band.
Additionally, you can use tools like iStumbler to check for less congested channels in your area. For example, choosing channel 4 when channels 3, 4, and 5 are free can improve your connection.
