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 Router Firmware:

Before you consider downloading this firmware, go to the system information page of the router and make sure that the currently installed version isn't either newer or matching this release.

Due to the large variety of router models and different methods for upgrading the device, it is highly recommended that you read and, above all, understand the installation steps before you apply the new firmware, even if you are a power user.

In theory, these steps shouldn't be much of a hassle for anyone, because manufacturers try to make them as easy as possible, even if they don't always succeed. Basically, you must upload the new firmware to the router through its administration page and allow it to upgrade.

If you install a new version, you can expect increased security levels, different vulnerability issues to be resolved, improved overall performance and transfer speeds, enhanced compatibility with other devices, added support for newly developed technologies, as well as several other changes.

If you're looking for certain safety measures, remember that it would be best if you perform the upload using an Ethernet cable rather than a wireless connection, which can be interrupted easily. Also, make sure you don't power off the router or use its buttons during the installation, if you wish avoid any malfunctions.

If this firmware meets your current needs, get the desired version and apply it to your router unit; if not, check with our website as often as possible so that you don't miss the update that will improve your device.
