Note: 
1  There is no need to upgrade the firmware unless the new firmware has a new feature you want to 
use. However, when experiencing problems caused by the device itself, you can try to upgrade the 
firmware. 
2  Before upgrading the device’s firmware, you should write down some of your customized settings to 
avoid losing important configuration settings of device. 
To upgrade the device's firmware, follow these instructions: 
1.  Download a more recent firmware upgrade file from the TP-LINK website (http://www.tp-link.com). 
2.  Enter the path name or click Browse… to select the downloaded file on the computer into the File 
blank. 
3. Click 
Upgrade. 
4.  The powerline extender will reboot while the upgrading has been finished.

Note: 
The firmware version must correspond to the hardware. The upgrade process takes a few moments and 
the powerline extender restarts automatically when the upgrade is complete. It is important to keep 
power applied until the system finishes upgrading and rebooting. Loss of power during the upgrade 
could damage the powerline extender.
