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 Wi-Fi interface:
# service netif restart wlan0
- Example 4: Scanning for Wi-Fi networks
-
% ifconfig wlan0 scan
- Example 5: Airplane mode
-
# service netif stop wlan0

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.
