If you're having trouble connecting to Wi-Fi on your Mac, you may need to turn on Airport. Airport is the name for Wi-Fi on older Mac machines, and you can enable it by going to the Apple/AirPort menu or the Network pane in System Preferences. You can also use the AirPort Utility app to manage your wireless network and base stations, or even create a new 'location' to get it working. If you're still having issues, you can try power cycling the wireless interface using the Terminal app, which may resolve basic wireless router connectivity issues.

What You'll Learn
Using the AirPort menu
The AirPort menu is a useful feature for Mac users, allowing them to manage their wireless connections. It is important to note that for newer Mac machines, Wi-Fi has replaced AirPort, so any reference to AirPort is the same as referring to Wi-Fi.
To access the AirPort menu, go to the Apple menu, then select System Preferences. From the View menu, choose Network. Here, you will find a list of available network connections, including AirPort.
The AirPort menu gives you the option to turn AirPort on or off. If you are experiencing connection problems, turning AirPort off and then on again can be a quick fix. You can do this by clicking on the AirPort icon and selecting "Turn AirPort On" or "Turn AirPort Off". You will know that AirPort is turned on when you see the bars reappear in the AirPort menu icon.
Additionally, the AirPort menu allows you to remove and add the AirPort interface. To remove it, click on the "-" button, and to add it, click on the "+" button. However, it is important to note that removing the AirPort interface will reset your preferred AirPort networks, so you will need to add them again.

Using the AirPort Utility app
The AirPort Utility app on your Mac can be used to set up and manage your wireless network and AirPort base stations, including AirPort Express, AirPort Extreme, and AirPort Time Capsule. You can also use the app to monitor your network and change base station and network settings.
To get started, open the AirPort Utility app on your Mac. If you don't have the app, you can download it from the App Store. Once the app is open, you'll see a graphical overview of your network and the devices connected to it. From here, you can perform a variety of tasks, such as:
- Setting up a new base station: Click on "Base Station" in the app and follow the instructions to set up your new base station.
- Monitoring your network: The app provides a real-time overview of your network's status, including any connected devices.
- Changing network settings: You can modify your network's settings, such as the security mode, wireless channel, and IPv6 configuration.
- Creating and managing complex networks: For more advanced users, you can create and manage larger networks, such as a WPA Enterprise network with a Radius server.

Troubleshooting AirPort wireless connection problems
If you're having problems with your AirPort wireless connection on your Mac, there are several troubleshooting steps you can take to try and resolve the issue.
First, try turning AirPort off and then on again. You can do this on your Mac by using the AirPort menu bar. If this quick fix doesn't work, you may need to investigate further.
Check your network settings and make sure your Mac is running on the latest software. You can use the AirPort Utility app on your Mac to monitor and manage your wireless network and AirPort base stations. This includes changing base station and network settings, as well as managing advanced features such as security modes and wireless channels.
If you're still experiencing difficulties, try changing the security protocol you use, from WPA/WPA2 to WPA2/WPA. Additionally, you can try restarting your Mac while holding down Option-D to launch Apple's hardware test and uncover any potential hardware issues. If there are problems with your Mac, you can use the Disk Utility app to "Verify Disk Permissions" and fix them.
If you're using an older AirPort model, such as the 1st Generation AirPort Express, you may encounter compatibility issues with newer software. In this case, you might need to reset your AirPort router and set it up again.
For more complex issues, it's recommended to seek further assistance from official Apple Support or consult a technical expert.

Using the command line
The airport command line tool is a utility for Wi-Fi on macOS/OS X. It is a powerful way to interact with a wireless card on a Mac. The tool allows you to manually adjust Wi-Fi settings, network card settings, troubleshoot networks, change security types used on a connection, capture packets into a pcap file, join and leave networks, and perform a variety of other network troubleshooting functions.
To use the airport command line tool, open Terminal on your Mac. You can then use the following commands:
- To get a list of flags and their functions, type `airport -h` or `airport –help`.
- To get information about the wireless network you're connected to, type `airport -I`.
- To run a wireless scan, type `airport -s`.
- To enable and disable AirPort Wireless, use the `networksetup` tool.
- To power cycle AirPort, type `airportcycle` and the wireless interface will turn off and on again.
Note that the airport command line tool is deprecated and will be removed in a future release. For diagnosing Wi-Fi-related issues, it is recommended to use the Wireless Diagnostics app or the `wdutil` command line tool.

Using an Ethernet cable
To turn on Airport on your Mac using an Ethernet cable, you can follow these steps:
Firstly, ensure that you have the necessary hardware. This includes an Ethernet cable, a router or modem, and an Ethernet port on your Mac. If your Mac does not have a built-in Ethernet port, you can use an Ethernet adapter such as the Belkin USB-C to Gigabit Ethernet Adapter, or a Thunderbolt to Gigabit Ethernet Adapter.
Next, connect the Ethernet cable to your router or modem. If you are using a modem, make sure it is turned on and set up according to the instructions provided by your Internet Service Provider (ISP). Plug the Ethernet cable into the WAN port on your base station, and then connect the other end of the cable to the Ethernet port on your Mac.
Once the physical connections are made, your Mac should automatically connect to the internet. If it does not, you can enter your network settings manually. Click on the Ethernet service and then click 'Details' to input the required information. If you are unsure of the network settings, you can refer to the information provided by your ISP or network administrator.
Additionally, you can create rules within your Mac's operating system to manage the connection settings. Go to the Network Preference Pane in System Preferences and set a Service Order. This allows you to determine which connection takes precedence when multiple options are available. For example, you can set a wired connection as the primary choice if available, and then fall back to the Airport network if the Ethernet cable is disconnected.
By following these steps, you can successfully turn on and manage your Airport connection on your Mac using an Ethernet cable.
