The Airport Express 619A7C router can be used as a WiFi bridge in a few different ways. If you want to connect the Airport Express to another router with Ethernet, you can set the Router mode to Bridge (off) and the WiFi mode to Create a wireless network, with the same SSID and password as the other router's WiFi network. This will create a roaming network. Alternatively, if you want to extend a WiFi network wirelessly, you can use the Extend a wireless network option in the WiFi settings. The Airport Express can also act as a wireless-to-wired bridge, where it joins a wireless network and routes the network to its Ethernet port. This feature is called ProxySTA and is available on recent versions of the Airport Express, but it is not documented in the AirPort Utility.

What You'll Learn
Wireless-to-wired bridge mode
The Apple AirPort Express can be used as a wireless-to-wired bridge, allowing users to extend their wireless network to wired clients. This is particularly useful for older devices that can only accept wired connections, such as older TVs or computers. To set up the AirPort Express as a wireless-to-wired bridge, follow these steps:
Firstly, ensure that your AirPort Express is connected to Ethernet. If you are using a non-Apple router, you will need to set it to share a public IP address. Set up the “network name” (SSID) and password to be the same on both your router and the AirPort Express. Make sure that your security mode is also consistent between the two.
Next, when configuring the AirPort Express, set the network mode to "Create a wireless network," and ensure that it is set to "Connect Using Ethernet." The Connection Sharing setting should be turned off, and the AirPort Express should be in Bridge Mode.
To activate ProxySTA, which enables the wireless-to-wired bridge functionality, you must set up the AirPort Express to join a wireless network. Then, enable the "Allow Ethernet Clients" setting. Both of these settings can be found in the Wireless tab of the AirPort Utility.
It is important to note that while recent versions of the AirPort Express support wireless-to-wired bridging, older versions may not. Additionally, some users have reported transmission errors or slower speeds when using this feature.
The wireless-to-wired bridge mode allows you to extend your wireless network to devices that require a wired connection. It acts as a transparent bridge, seamlessly connecting wireless and wired devices. With the AirPort Express in bridge mode, it functions as a dynamic host configuration protocol and network address translation server, enhancing your network's performance and optimisation of roaming.

Extending a non-Apple network
The Airport Express can be used to extend a non-Apple network, but it is not straightforward and may not always be successful.
Firstly, the Airport Express needs to be connected to Ethernet. The non-Apple router must be set to share a public IP address. When setting up the Airport Express, the network name and password must be the same as the non-Apple network. The network mode should be set to "Create a wireless network," with the connection type as "Ethernet," and Connection Sharing must be "Off (Bridge mode)."
Some users have reported success with this method, but others have encountered issues. One user reported that they were unable to make the Airport Express extend anything other than another Apple router. Another user suggested that the Airport Express can only join a third-party network, rather than extend it, and that a roaming network is created when two routers are connected via Ethernet with the same network name and password.
To summarise, while it is possible to use an Airport Express to extend a non-Apple network, it may require some trial and error, and there is no guarantee of success. Users should be prepared to encounter issues and may need to explore alternative solutions.

ProxySTA mode
The ProxySTA mode is a feature of the Airport Express router that allows it to act as a wireless-to-Ethernet bridge, extending your wireless network to wired clients. In this mode, the Airport Express acts as a simple wireless client, connecting to your wireless network and allowing Ethernet clients to connect to the network through its Ethernet port.
To set up the ProxySTA mode on your Airport Express router, follow these steps:
- Connect the Express to Ethernet: Ensure that the Airport Express is connected to your network via an Ethernet cable.
- Configure Network Settings: Set up the “Network name" (SSID) and password of the Airport Express to match those of your existing wireless network. This includes setting the same security mode (e.g., WPA2-Personal).
- Join a Wireless Network: Using the Airport Utility, set up the Express to join your wireless network. This can be done by selecting the "Join WiFi Network" option or similar in the settings.
- Enable "Allow Ethernet Clients": In the Airport Utility, navigate to the Wireless tab and enable the "Allow Ethernet Clients" setting. This setting allows devices connected to the Ethernet port of the Airport Express to access the wireless network.
- Update Firmware (if needed): Note that for the ProxySTA feature to appear, your Airport Express may need to be updated to firmware 7.3.1 or later.
By following these steps, you can enable the ProxySTA mode on your Airport Express 619A7C router, allowing it to function as a wireless bridge and extend your wireless network to devices connected via Ethernet.
It is worth noting that while ProxySTA mode offers easier setup and potential improvements in wired-to-wireless performance compared to WDS (Wireless Distribution System), it may not be officially documented or named within the Airport Utility interface. Additionally, the Airport Express can act as a bridge in other ways, such as through WDS remote or relay station configurations, but these may be more complex to set up and may have some compatibility limitations.

WDS remote or relay station
The Apple AirPort Express can be used as a wireless-to-wired bridge in several ways. One way is to set it up as a WDS (Wireless Distribution System) remote or relay station, which allows it to bridge a wireless network to wired clients. This setup typically involves using the Airport Express in conjunction with other Apple base stations, such as the AirPort Extreme or Time Capsule.
To set up a WDS network, you need to configure the Airport Express and the other base stations to participate in WDS. This includes assigning each device a specific role, such as main, remote, or relay base station, and ensuring they all have the same network password. You can set up multiple AirPort Express base stations as part of a WDS network to extend the range of your wireless network.
When setting up a WDS remote or relay station, you will need to access the AirPort Utility and select the appropriate options. For a WDS remote station, you would choose "WDS remote" from the pop-up menu, enter the AirPort ID of the Main base station, and update the settings. For a WDS relay station, you would choose "Manual Setup" from the Base Station menu, enter the network password if necessary, select "Participate in a WDS network" from the Wireless Mode pop-up menu, and choose the appropriate channel.
It's important to note that while the AirPort Express can act as a wireless bridge in most modes, including 802.11n-exclusive mode, it may suffer from transmission errors in 802.11b/g-compatible modes, which can result in packet loss within the local network. Additionally, when extending a wireless network, it is recommended to use the same SSID and security mode across all access points to ensure a seamless connection for your devices.
