●  It is recommended to upgrade the firmware via Ethernet cable connection but not wireless 
connection;

There are two methods to upgrade the firmware: 
1)  Upgrade the firmware via web management page of the PharOS devices. 
2)  Batch upgrade the firmware via centralized management software Pharos Control. 
When you have many Pharos series devices that need to be upgraded, the Method 2 is recommended, 
since it supports batch and scheduled upgrade; while if you have only one or two Pharos series 
devices, you can choose method 1). 
 
Preparation: 
1.  Please verify the product model and the hardware version of your device from the label on the 
bottom of the device to make sure you are using the correct firmware. Wrong firmware 
upgrading may damage your device and void the warranty.

hardware version (V1).

version from the TP-LINK official website http://www.tp-link.com/en/support.html. And then
