How to see the list of devices connected to your Airport network
To see the list of devices connected to your Airport network, you can use the Airport Utility. When you first open the Airport Utility, it shows a graphical overview of your Wi-Fi network, including any base stations and devices connected to it. The base station's name and status are also shown in the overview.
To see the list of wireless clients connected to your Airport Extreme base station, select your base station. A pop-up window will appear, and any connected clients will show up under "wireless clients". Move your mouse cursor over a client, and another pop-up window will appear with additional status information.
To view more details about each client, click on the disclosure triangle (the little grey triangle next to each device name) to expand the information. For each client, you can see the connection quality, data rate, IPv4 address, hardware (MAC) address, RSSI, and Wi-Fi mode(s).
If you want to see the IP, Mac, and network name for WiFi devices, hold the option key and then double-click on the AirPort device providing DHCP services. A new 'Summary' tab will appear, and you can click on the outline icon in the wireless client list to see details.
Alternatively, you can use third-party applications such as Fing (available for Android and iOS devices) or iNet to scan your network and display a list of connected devices along with their hostnames and IP addresses.

How to set up a guest network
Setting up a guest network is a smart move for keeping your home internet more secure. It lets visitors connect to your Wi-Fi router and use your internet without accessing your personal devices.
There are two ways to go about setting up your guest Wi-Fi network, and the available method depends on your internet service provider and your router. Most new routers, including those provided by ISPs like AT&T, CenturyLink, Verizon Fios, and Xfinity, feature an app that lets you access and manage your Wi-Fi network. Each provider or router app will look a little different, but the option to create a guest Wi-Fi network should be relatively easy to find.
Once you've reached the guest Wi-Fi settings, enter your desired network name and password, then apply the changes. Your guests can connect to the new network the same way they would to any other Wi-Fi network: by selecting it from their device's list of available nearby networks and entering the password. You can also print a QR code to make it easier for guests to connect to your network.
If your router doesn't have an app, you can still set up a guest network by following these steps:
- Enter your router's IP address into your preferred browser. You can usually find this information on your device's Wi-Fi settings.
- Log in to your router by entering your router credentials. This information can often be found on your router, possibly on the bottom.
- Once you're logged in, look for guest Wi-Fi settings. If you can't find it right away, check under Wireless Settings or Network Settings.
- Enable the guest Wi-Fi network and create your desired network name and password.
- Save your new settings, and your guest network should now be ready for use.
By setting up a guest network, you can ensure that your personal devices and information remain secure while still providing internet access to your guests.

How to set up a base station
Setting up a base station can be done in several ways, depending on the hardware and software you are using. Here is a step-by-step guide on how to set up a base station for a Mac using AirPort Utility:
Step 1: Connect the Modem
Connect the modem provided by your Internet Service Provider (ISP) to your AirPort Extreme using an Ethernet cable. Use the cable to connect to the bottom-most port on the back of the AirPort Base Station. Don't worry if you make a mistake; you will be prompted to fix things during the setup.
Step 2: Launch AirPort Utility
On your Mac, launch the AirPort Utility app, which can be found in the Utilities folder within the Applications folder.
Step 3: Configure the Base Station
Click on "Other WiFi Devices" in the upper right corner and then click "Other Options" to set up the AirPort for additional capabilities. Click "Next".
Step 4: Enter Network Information
Enter a Network Name and a Base Station Name. You can leave these as the default or change them as preferred. Enter a password for your network. It is recommended to have separate passwords for added security. If you have a Base Station with an internal hard drive, such as a Time Capsule, you can also choose a separate password for it.
Step 5: Enable Guest Network (Optional)
If you want to enable a guest network, click on the "Wireless" tab, then check "Enable Guest Network". Enter a new network name that is easily discernible from your regular "secured" network. Select your desired level of Guest Network Security: choose "None" for an open network or "WPA2" for a secure network. If you select WPA2 Personal, enter and verify your Guest Network Password.
Step 6: Restart and Connect Devices
Restart your Base Station. You can now start connecting your Wi-Fi-capable devices to your new access point. Depending on your coverage requirements, you may need to extend your network by installing additional access points in bridged mode.
Note: After completing the setup process, you have additional options for configuring your network, such as keeping your base station up to date and connecting storage devices for file sharing.
