Apple's Airport Express is a popular device for extending Wi-Fi networks. While it can be used to extend both 2.4 GHz and 5 GHz networks, some users have reported issues when trying to extend only the 5 GHz network. This issue seems to be related to how the Airport Express is set up and configured, with some users finding workarounds by using specific settings or different hardware. In some cases, users have found that the Airport Express will only extend the 2.4 GHz network or will automatically switch between the two bands depending on signal strength. Understanding the behaviour of the Airport Express when extending Wi-Fi networks is important for optimizing wireless connectivity in homes and offices.
| Characteristics | Values |
|---|---|
| Extending 5GHz network | If you have a dual-band Apple router, the Airport Express will extend both 2.4 GHz and 5 GHz bands if they have the same wireless network name. |
| If you assign a separate name to the 5 GHz network on the main router, the Airport Express will only extend the 5 GHz band. | |
| The Airport Express cannot extend both 2.4 GHz and 5 GHz bands at the same time if they have different names. | |
| Creating a 5GHz network | The Airport Express can create a 2.4 GHz or 5 GHz network. |
| Connecting to a 5GHz network | The Airport Express can connect to a 5 GHz network, but your device may still connect to the 2.4 GHz network if it is better suited to your current reception characteristics. |

The new Airport Express can create a 5GHz network but only extends 2.4GHz
The new Apple Airport Express can create a 5GHz network but can only extend a 2.4GHz network. This limitation is not present in the Airport Extreme, which can extend both 2.4GHz and 5GHz networks.
To create a 5GHz network with the new Airport Express, users must set up the device with a 5GHz network. However, when attempting to extend an existing 5GHz network, the new Airport Express will only extend the 2.4GHz band. This issue appears to be a limitation of the Airport Express hardware or software.
Some users have found a workaround for this issue by setting up their main router to use the same network name for both the 2.4GHz and 5GHz bands. With this setup, the Airport Express will extend both bands. However, if a separate name is assigned to the 5GHz network, the Airport Express will only extend that specific band and not the 2.4GHz band.
It is worth noting that 5GHz signals are weaker than 2.4GHz signals and are more easily absorbed by walls and ceilings. This may impact the performance of the Airport Express when extending a 5GHz network, especially if it is not located close to the main router.
Apple Support has acknowledged the limitation of the current Airport Express extender option and stated that the hardware is capable of dual-band extension. They have suggested that a firmware update may resolve this issue in the future.

To extend 5GHz, use a single network name for both bands on the main router
To extend a 5GHz network with an Apple Airport Express, you need to use a single network name for both the 2.4 GHz and 5 GHz bands on the main router. This is because the Airport Express is limited to extending one network, so it cannot extend both bands if they have separate names.
By using the same network name for both bands, you allow devices to automatically connect to the highest band that they can support. For example, if a device can only use 2.4 GHz, it will connect to that band, but if it can use 5GHz, it will. This setup also ensures that your devices will always have the best possible speed based on signal strength, as they can switch between bands as needed without any manual intervention.
To set up a single network name for both bands on your Apple router, open the Airport Utility application. You can then change the settings to give both bands the same name.
It is worth noting that some older devices may require a separate 2.4GHz band during the initial configuration. In these cases, you can temporarily provide separate band names and then switch back to a single network name once the configuration is complete.

To extend 5GHz, set up WDS for 5GHz on both access points
To extend a 5GHz network, you need to set up Wireless Distribution System (WDS) for 5GHz on both access points. WDS is a system that can be used to extend wireless LANs or connect wired LANs where a cable isn't practical. It can be enabled in either 2.4GHz or 5GHz frequency for a dual-band router.
To set up WDS for 5GHz, you need to follow these steps:
- Log in to the web-based interface of the router.
- Go to Advanced > Network > LAN, and configure the IP address of the extended router to be in the same subnet as the root router.
- Go to Advanced > System Tools > System Parameters, and enable WDS bridging in the 5GHz Wireless section.
- Make sure that all APs in the WDS network are on the same channel to ensure proper communication. For 5GHz WLANs, you can use Channel 1, 6, or 11.
- Set a different SSID for each AP. WDS APs identify each other by MAC address, while wireless clients associate by SSID.
- Convert one of the routers to an access point. This can be done by disabling the router's firewall and setting it to AP Router Mode.
It is important to note that WDS has some limitations and compatibility issues. It is limited to using WEP encryption, which may sacrifice throughput when used with 802.11n gear. Additionally, it can be difficult to configure and may not work with all routers.

To extend 5GHz, configure the Airport Express to extend the band with the same name as the main router's 5GHz band
The Airport Express can extend a 5GHz network, but there are some limitations and specific steps that need to be followed for it to work. Firstly, it is important to note that the Airport Express can only extend one network at a time. So, if you want to extend both the 2.4GHz and 5GHz networks, you will need two Airport Express devices, one for each network.
To extend the 5GHz network, the main dual-band Apple router should be set up so that both the 2.4GHz and 5GHz bands use the same wireless network name. This way, the Airport Express will extend both bands. If you want to extend only the 5GHz band, you can assign a separate name to the 5GHz network on the main router, and then configure the Airport Express to extend that specific band. It is important to note that if you set up the Airport Express with a 5GHz network, it may not show up in the list of available networks. This seems to be a common issue with the Airport Express, and a possible solution is to use a wired Ethernet backhaul between the access points.
When setting up the Airport Express to extend the 5GHz network, make sure to set up WDS for 5GHz on both access points to "extend" the network. Additionally, ensure that the wireless network name, wireless security type, and wireless network password are the same for both the main router and the Airport Express. Once these steps are completed, the Airport Express should be able to extend the 5GHz network successfully.
It is worth noting that 5GHz signals are weaker than 2.4GHz signals and are more easily absorbed by walls and ceilings. Therefore, it is recommended to place the Airport Express close to the main router to ensure optimal signal strength for the extended 5GHz network.

To force a PC to use 5GHz, remove the 2.4GHz network from known networks
The 5GHz Wi-Fi band offers faster speeds and less network congestion compared to the 2.4GHz band. However, it has a shorter range and experiences more difficulty penetrating solid objects. To force a PC to use the 5GHz band, you must first ensure that all your devices are 5GHz-compatible. This is because older devices, such as a Roku, game console, or Kindle, may only support the 2.4GHz band.
If you are certain that all your devices can operate on 5GHz, you can disable the 2.4GHz network. To do this, access your router's browser-based configuration interface. Here, you will find separate controls for the 2.4GHz and 5GHz networks. Simply turn off or disable the 2.4GHz network. This process may vary slightly depending on your specific router model and manufacturer.
For example, if you are using an Apple AirPort Express, you can set up each band individually. You will need to configure your AirPort Express to extend the network of the AirPort Extreme. If you have a mid-2012 AirPort Express, it will automatically connect to the Extreme on the same band and make that network available over both 2.4GHz and 5GHz.
Additionally, when using a Windows 10 PC, you may encounter a situation where your computer automatically connects to the 2.4GHz network instead of the 5GHz network. In this case, you can check if your wireless adapter is compatible with the 5GHz band and ensure that your network settings are configured correctly.
