Make sure the communication parameter shows that the correct protocol is used such as Telnet or
SSH with 3DES. You can try a manual SSH or Telnet from an SSH/Telnet client on a PC in order to
check the username and password credentials are correct. Then try to Telnet or SSH from the Sensor
itself to the router and see if you can login successfully to the router.
