- Corrected the service restart commands to use the proper syntax for stopping and starting the WAN interface. - Improved the ping test logic to return success or failure directly, simplifying the main script execution. - Enhanced error logging by redirecting standard error output to the log file during the ping test. - Streamlined the ping command to use the configured PING_HOST variable directly. - Ensured that the script properly handles return values from the ping test function. These changes improve the reliability and clarity of the WAN monitoring functionality.
