NETWORKING(7)

NAME
networking, wifi - quickstart guide to connecting to a network

DESCRIPTION
In the following examples, it is assumed that we are connecting to Ethernet with the first interface found by the ix(4) driver, and Wi-Fi with the first interface found by the iwlwifi(4) driver, though your hardware will vary.

EXAMPLES

Example 1: Connecting to an Ethernet network with DHCP

    Ask for a DHCP lease on the first Intel 10Gb Ethernet interface:

        # dhclient ix0

Example 2: Connecting to a cellular network with USB tethering

    Ask for a DHCP lease on the first USB tethering interface:

        # dhclient ue0

Example 3: Connecting to a Wi-Fi network

    Identify your Wi-Fi hardware:

        % sysctl net.wlan.devices

    Create the wlan0 interface with the first Intel Wi-Fi adapter:

        # sysrc wlans_iwlwifi0="wlan0"

    Set that interface to ask for a DHCP lease with wpa_supplicant(8):

        # sysrc ifconfig_wlan0="WPA SYNCDHCP"

    Enter the details of the Wi-Fi network:

        # cd /etc/
        # wpa_passphrase "myssid" "mypassphrase" >> wpa_supplicant.conf

    Restart the network interface daemon:

        # service netif restart

Example 4: Scanning for Wi-Fi networks

        % ifconfig wlan0 scan

Example 5: Airplane mode

        # service netif stop

CAVEATS
Shell Special Characters in the SSID or passphrase will need to be escaped for wpa_passphrase(8), commonly using ‘\’, see the manual page for your shell for more details.

Stopping the network interface service also stops internal networking.
