wpa_supplicant configurations are stored in /etc/wpa_supplicant/wpa_supplicant-wlan0 (or equivalent).
# Generating Keys Manually
> wpa_passphrase [ssid] [password]
For example:
> wpa_passphrase 'Cafe Kosachok' 'Kosachok2019'
This then spills the relevant psk and such to be entered into the wpa_supplicant configuration file.
If you encounter problems, you will probably need to delete the old device pid in (e.g.) /run/wlan0/
Next up, start wpa_supplicant:
> wpa_supplicant -B -iwlan0 -c /etc/wpa_supplicant/wpa_supplicant-wlan0
The -B flag runs this as a background process. Remove this to see real-time output in order to solve problems. The -i flag denotes the physical device used for the wifi. The -c flag points to the configuration file for use.

This has a number of commands to input. In order:

> add_Network
2020-01-02 00:04:35 +00:00
2022-01-26 22:35:07 +00:00
This outputs a Network number, e.g. '3'. This is the new Network you'll work with.
