# Description
#   Connects to the given SSID with the given password.
# Parameters
#   $1: the SSID name
#   $2: the SSID password
# Retruns
#   No specific response.
# Considerations 
#   For security reasons the system is not allowed to connect to a passwordless AP.
#   Therefore an empty password is an error.

# TODO
#   Add static connection
#   The static IP enable shall only be a boolean argument for this script.
#   When set to 1(true), the corretly defined connection will be made static.
