To Upgrade

IMPORTANT: To prevent upgrade failures, please read the following before proceeding with the upgrade process

- Please upgrade firmware from the local TP-Link official website of the purchase location for your TP-Link device, otherwise it will be against the warranty. 
- Please verify the hardware version of your device for the firmware version. Wrong firmware upgrade may damage your device and void the warranty. (Normally Vx.0=Vx.6/Vx.8 (eg:V1.0=V1.6/V1.8); Vx.x0=Vx.x6/Vx.x8 (eg:V1.20=V1.26/V1.28)
- Do NOT turn off the power during the upgrade process, as it may cause permanent damage to the product.
- To avoid wireless disconnect issue during firmware upgrade process, it's recommended to upload firmware with wired connection unless there is no LAN/Ethernet port on your TP-Link device.
- It's recommended that users stop all Internet applications on the computer, or simply disconnect Internet line from the device before the upgrade.

About Switch Firmware:

Given the large variety of models and different methods for upgrading the switch, if you wish to apply this package, we recommend that you read and understand the installation steps before you install a new firmware, even if you are a power user.

Usually the update procedure isn't much of a hassle as manufacturers try to make it as simple as possible; however, there are cases that are exceptions to this rule. First off, go to the system information page of the switch to check that the currently installed version isn't either newer or matching this release.

Applying a new firmware can decrease the security vulnerabilities, enhance overall performance and compatibility, improve various power management functions, resolve different errors, and add support for newly developed technologies and protocols.

It is recommended that you perform this step in a steady power environment such as the one ensured by a UPS unit, and that you don't interrupt the upgrade in any way, because this might cause the switch to malfunction.

That being said, click the download button, get and apply the new version, and check back with our website constantly to stay up to speed with the latest releases.
