- Make sure your computer has an IP address in the same subnet as the PMG1005-T20C. If your 
   PMG1005-T20C is using the default IP address, then your computer should have an IP address from 
   192.168.1.2 to 192.168.1.254. See your computer help. 
- Make sure you are using the correct IP address.

• The default IP address is 192.168.1.1.
• If you changed the IP address and have forgotten it, you have to reset the PMG1005-T20C to its 
  factory defaults.

password, use a pin to push the RESET button for more than 5 seconds to return the device to the 

factory defaults, including  admin password on the back label.

- Check the hardware connections and the LED behavior. If the 

PON

 LED is off, restart the
