There are several ways to measure the WiFi signal strength of an Apple Airport Extreme base station. One way is to use the AirPort Utility app on an iPhone by selecting the base station that the iPhone is connected to, selecting Wireless Clients, then selecting the MAC address of the iPhone, and finally selecting Connection to note the RSSI value, which is measured in dBm. Another way is to hold the Alt (option) key while clicking the WiFi icon in the menu bar, though this method does not show which airport the signal is coming from. A third way is to use third-party apps such as WiFi Scanner, CloudCheck, or NetUse, though these apps may require additional purchases or dongles.

What You'll Learn
Using the WiFi Scanner app
The WiFi Scanner app is a useful tool for measuring the signal strength of your Wi-Fi connection. It is available on the Apple App Store for iOS devices and provides detailed information about your Wi-Fi network.
To use the WiFi Scanner app to measure the signal coming from Airport Extreme, you can follow these steps:
- Open the WiFi Scanner app and ensure that you have granted the necessary permissions for it to function properly.
- Within the app, look for an option to start scanning for Wi-Fi networks. This may be labelled as "Scan" or "Wi-Fi Search".
- Initiate the scan to begin detecting nearby Wi-Fi networks, including Airport Extreme.
- Once the scan is complete, the app will display a list of all detected Wi-Fi networks, including their respective signal strengths.
- Locate Airport Extreme in the list of networks and note its signal strength. This will be indicated in dBm or RSSI values, which represent the strength of the Wi-Fi signal.
The dBm ratings typically range from -30 (strongest) to -90 (weakest). Therefore, a higher negative number indicates a stronger connection. For example, a reading of -30 dBm signifies a perfect connection, often achieved when standing close to the Wi-Fi router.
By using the WiFi Scanner app, you can gain insights into the signal strength of your Airport Extreme network. This information can help you optimise your Wi-Fi setup and improve your overall connection quality if needed.

Holding Alt and clicking the WiFi icon
To measure the WiFi signal coming from an Airport Extreme, you can try holding the Alt key while clicking the WiFi icon on your device. This will show you the signal strength, but it won't indicate which airport you are connected to.
For more detailed information, you can try using a WiFi scanning app. There are free and paid options available for download, such as WiFi Scanner or CloudCheck. These apps can provide a more comprehensive view of your WiFi signal strength and connection details.
Additionally, you can try using the Airport Utility on your device. Go to Settings > WiFi and select your base station, which may be named something like "AirPort Extreme 0affff". From there, follow the on-screen instructions to set up and extend your network.
Another option is to use an Ethernet cable to connect your base stations. This provides better throughput than a wireless connection. Connect one end of the Ethernet cable to the WAN port on one base station and the other end to a LAN port on the primary base station.
By following these steps, you should be able to measure and improve the WiFi signal coming from your Airport Extreme.

Using the AirPort Utility app
To measure the WiFi signal strength of an Airport Extreme base station using the AirPort Utility app, follow these steps:
First, enable the Wi-Fi scanner in the app. On iOS devices, open your device Settings, tap AirPort Utility from the list, and toggle on "Wi-Fi Scanner". For Windows, the AirPort Utility for Windows > Logging and Statistics > Logs and Statistics > Wireless Clients tab. Once enabled, open the AirPort Utility app.
Now, you can start scanning for WiFi signals. In the app, you will find a "Wi-Fi Scan" option in the upper right-hand corner. Select this, choose the desired scan duration, and then select "Scan". The app will now scan for WiFi signals, including the signal from your Airport Extreme base station.
After the scan is complete, you will see the results, which include the RSSI value. RSSI stands for Received Signal Strength Indicator and is measured in dBm (decibels relative to a milliwatt). The dBm ratings range between -30 (strongest) and -90 (weakest). For example, a reading of "-70 dBm" indicates a stronger connection than -74 dBm.
By using the AirPort Utility app and following these steps, you can measure and evaluate the WiFi signal strength coming from your Airport Extreme base station.

Using an Ethernet cable
To set up this method, you will need an Ethernet cable long enough to reach from your device to the airport extreme. Once you have the necessary equipment, follow these steps:
- Connect one end of the Ethernet cable to your device, such as a laptop or desktop computer.
- Connect the other end of the Ethernet cable to the Ethernet port on the airport extreme.
- Ensure that your device is set to obtain an IP address automatically. This is usually the default setting, but it's worth checking to make sure.
- Open a web browser or a network scanning tool on your device.
- Perform a speed test or use a network scanning tool to measure the network speed and signal strength.
It is worth noting that while this method provides a more controlled environment for measurement, it may not represent the typical WiFi experience of wireless devices connected to the airport extreme. However, it can help identify if there are any issues with the Ethernet connection or the network itself.

Using the RSSI value
RSSI stands for "Received Signal Strength Indicator". It is a measurement of how well your device can hear a signal from an access point or router. RSSI is a relative index with no absolute value. It is useful for determining if you have enough signal for a good wireless connection.
RSSI values are usually displayed in dBm (decibels relative to a milliwatt) and are expressed as negative numbers. The dBm scale typically runs from -30 (strongest) to -90 (weakest). The closer the value is to 0 dBm, the better the signal.
To measure the RSSI value of your WiFi signal, you can use a WiFi scanning app. These apps provide a more precise measurement of your WiFi signal strength compared to simply looking at the bars on your device.
- AirPort Utility (iPhone, iPad)
- WiFi Analyzer (Android)
- WifiInfoView (Windows)
- WiFi Scanner (iOS, macOS)
By using one of these apps, you can determine the RSSI value of your WiFi signal coming from Airport Extreme and assess the quality of your wireless connection. Keep in mind that factors such as distance from the router, the frequency band (2.4 or 5 GHz), and the materials of surrounding walls can affect your signal strength.

Frequently asked questions
You can measure the WiFi signal strength using the AirPort Utility app on your iPhone or iPad. First, go to your device settings and turn on the Wi-Fi scanner. Then, open the AirPort Utility app and start a scan to see the dBm measurements expressed as RSSI.
RSSI stands for Received Signal Strength Indicator. It is measured in dBm, which is short for decibels relative to a milliwatt. The dBm scale runs from -30 (strongest) to -90 (weakest).
The signal strength depends on various factors, including distance from the router, broadcasting power value, and whether it's a 2.4 or 5 GHz connection. Obstructions like walls can also impact the signal strength.
To improve signal strength, consider the placement of your Airport Extreme. Obstructions and distance can weaken the signal. You can also try creating a WiFi heatmap of your home to identify areas of weak signal and determine if a mesh router or additional access points are needed.
