Network Name & Password Entry: Your wireless name AND password are case sensitive. You MUST match the EXACT name of your SSID or it will NOT work correctly.
Editing the File: Do NOT use a simple text editor like Notepad. Use one that supports the formatting of the file like Notepad++. If you use a built-in text editor (like notepad) it will not work.
If you messed up your octopi-wpa-supplicant.txt file or want to start over you can download a fresh copy below. Copy the downloaded file onto your EZPi SD card, overwriting the old one and then edit the new file with your information using the information in the video below.
NOTE: When removing the SD card be careful as they are delicate devices. Warranty does not cover if you crack the SD card when removing from the EZPi case.
