• Password not found:

  • Linux:
    • Make sure your network passwords are stored correctly in NetworkManager's storage directory. This is in /etc/NetworkManager/system-connections/. NetworkManager can work by checking if the passwords are stored with another program, but you need to store them in this directory for this program to work.
  • MacOS/Windows:
    • You probably have something broken with your WiFi storage. If not, submit an issue to this repository with information.

• NetworkManager isn't installed:

  • This program does not work without NetworkManager on Linux. If you want to use this program, install it using your distributions package manager or software center. Not using NetworkManager is a strange decision, but that's an issue for another time.

• Have another issue?

  • Open a useful issue on this GitHub, and/or suggest a new item in this list if you find a solution.

• This project is an improvement of wifi-password created by @rauchg, where I have added support for multiple platforms and have added the feature for generating QR codes.
• wifiPassword created by @ankitjain28may was frequently used as reference throughout the development of this project.
