Oblivian has given right instructions.

However I would like to elaborate it for those not familiar with linux as follows:

The method in the linked post is for configuring WiFi without connecting monitor+keyboard to RPI, and without network connection and without SSH. This is achieved by slipping the microSD card in card reader of Laptop/Desktop, and creating the file wpa_supplicant.conf in the /boot folder.

When the microSD card is slipped-out from card reader and slipped into RPi, and RPi is booted, this file is automatically moved to folder /etc/wpa_supplicant/ and replaces any existing copy of wpa_supplicant.conf there. Therefore after booting Pi, you cant find it in /boot folder. You will find it in /etc/wpa_supplicant/ folder.

To make any changes to SSID and WiFi password using SSH, edit file wpa_supplicant.conf by following command:

sudo nano /etc/wpa_supplicant/wpa_supplicant.conf

After making changes, Save file (Ctrl+o) and Close it (Ctrl+x).
You may need to reboot or power-off/power-on RPi for changes to take affect
