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.
