FreeBSD Wireless Networking Setup

Jul 19, 2023 • FreeBSDSoftware

FreeBSD is a free and open-source Unix-like operating system that powers modern servers, desktops, and embedded platforms. One key aspect of managing a FreeBSD system is its network configuration, especially wireless networking. In today’s digitized world, optimizing and properly setting up your wireless network can improve the performance and reliability of your system. This article walks you through the steps to set up wireless networking on FreeBSD.

Before we dive into wireless networking, we recommend reading our introduction to networking in FreeBSD post to get familiar with basic networking concepts on FreeBSD.

Getting Started

To start with the setup process, you need the name of your wireless network interface. Run the ifconfig command to check the interface’s name.

The output should resemble wlan0. In FreeBSD, wireless interfaces start with wlan. You also require the ssid of the wireless network you intend to connect to and the WPA2 key, if any.

$ ifconfig

Create a WLAN Device

Creating a WLAN device requires some configurations. The cloned_interfaces statement in your /etc/rc.conf file needs to contain the name of your wireless interface:

echo 'cloned_interfaces="wlan0"' >> /etc/rc.conf

When the system boots, the wireless interfaces defined in the cloned_interfaces will be created automatically.

Connect to the Wireless Network

Now comes the exciting part. After creating the WLAN device, the next thing is to connect to the wireless network:

echo 'ifconfig_wlan0="WPA SYNCDHCP"' >> /etc/rc.conf

This command configures the wlan0 device to use WPA for authorization and DHCP for IP address. The SYNCDHCP parameter synchronizes DHCP with the WPA handshake process.

Once completed, restart the network service or reboot your system to effect the configurations:

service netif restart

To confirm you’re connected, run the ifconfig wlan0 command. If it depicts you’re connected, then we’re all set and congrats!


If you encounter issues with your wireless networking setup, you can start diagnostics using the ifconfig command to check the status of your network interfaces. You might also want to check out our guide on FreeBSD network configuration and troubleshooting.

Staying Secure

While setting up your wireless networking in FreeBSD, remember to uphold security measures. You may find our articles about Implementing Firewalls and Security in FreeBSD and Best Practices for System Hardening and Security in FreeBSD useful.


Wireless networking setup in FreeBSD is not complicated if you know the right procedures. This guide was intended to aid users in setting up and connecting their FreeBSD systems to Wi-Fi networks. Now you should have a FreeBSD system that can connect, configure, and troubleshoot your wireless networks.

Remember that understanding configurations and commands on your FreeBSD system can make the administration process simpler.
