This page covers methods of connecting to wifi from Linux.
The methods break down as follows:
- Use
/etc/network/interfaces - Use wpa supplicant
- How to connect to encrypted vs. unencrypted wifi
Use etc network interfaces

To set the wireless network you want a Linux box to join, you can add the network name and passphrase to /etc/network/interfaces. Better yet, you can create one file for each network you want to have ready to go, and swap them in and out by sourcing them or not from the /etc/network/interfaces file.
First, put the wifi configuration information into a file. This will be called mynetwork.cfg, and will be stored in /etc/network/interfaces.d/mynetwork.cfg.
auto wlan0 allow-hotplug wlan0 iface wlan0 inet dhcp wpa-ssid NetName wpa-psk NetPassword
The next step is to reference this configuration file from the /etc/network/interfaces file. Here is what that file looks like:
source /etc/network/interfaces.d/mynetwork.cfg
The /etc/network/interfaces.d/ folder would contain credentials for several networks, and could be swapped out by editing /etc/network/interfaces.
