 Note: 
1.  New firmware versions are posted at http://www.tp-link.com and can be downloaded for free. 
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 router rather than the 
configuration, you can try to upgrade the firmware. 
2.  When you upgrade the router's firmware, you may lose its current configurations, so before 
upgrading the firmware please write down some of your customized settings to avoid losing 
important settings. 
3.  Do not turn off the router or press the Reset button while the firmware is being upgraded. 
Loss of power during the upgrade could damage the router.   
4.  The firmware version must correspond to the hardware.   
5.  The upgrade process takes a few moments and the router restarts automatically when the 
upgrade is complete.
