Where is my `/etc/wpa_supplicant.conf` on systemd? Before `systemd`, I could just simply edit `/etc/wpa_supplicant.conf` file to add my desired network with pre-shared key: $ cat /etc/wpa_supplicant.conf network={ ssid="TPLINK" psk="My secret pre-shared key" } But on `systemd`, where is my `/etc/wpa_supplicant.conf`? How can I edit my network and pre-shared key?

`man wpa_supplicant`:

> First, make a configuration file, e.g. `/etc/wpa_supplicant.conf`, that describes the networks you are interested in. See wpa_supplicant.conf(5) for details.

Alternatively, you could create the file at `/etc/wpa_supplicant/yourconfig.conf`.
