GT784WN Firmware Upgrade NCS01-1.0.13


This upgrade will restore your device to factory defaults, erasing all user names, passwords, wireless settings and advanced custom configurations that you have made. Be sure to make note of any custom settings before upgrading your unit.

Actiontec Electronics will not provide a refund or replacement, for products that have failed due to the loading of incorrect firmware or the testing of custom firmware.

(To identify your Actiontec product, look for the model number. It is located on the FCC sticker, found on the bottom or back of the product. Typically the model number is in the sticker's upper right-hand corner.)

This Firmware Upgrade (NCS01-1.0.13) is for the GT784WN ONLY. It is not to be used on any other model of router or gateway. This is an NCS (Non-Customer Specific) Firmware and is not intended as an Upgrade for ANY ISP Specific Firmware, regardless of version number. Therefore, you should not load an NCS Firmware Upgrade on to a gateway that currently has an ISP Specific Firmware installed. The reverse is also true. You should not load an ISP Specific Firmware Upgrade on to a gateway that currently has an NCS version installed. These types of Upgrades frequently result in a nonfunctional device.

Clicking the link below will initiate the download, and at the prompt 'Do you want to run or save this file?' select 'Save'. At the following 'Save As' dialog, be sure to select a familiar location to save the file, like 'My Documents' or the 'Desktop', so that the file will be easy to find later.

  • When the firmware upgrade file download is complete, I get a message that "the file could not be mounted, image file is corrupt"...

  • John,

    I have checked the files check sum with a known working copy and they match. Which means the file is not corrupt on the website. Can you try using a different computer to download the file to see if that works, then get back to us?

  • Is this Firmware recommended? Does it fix something critical? What does it change?

  • Chuck,

    All the updates with this .13 firmware release are related to the backend functionality of the device.

  • So I probably don't need to apply it as a consumer?

  • Correct, there is no need to upgrade unless you are beginning to experience issues with your modem.

  • Will there be an upgrade to the GT784xxx firmware to address the Key Reinstallation Attack (KRACK) vulnernabilities?

  • Jim,

    Actiontec is aware of this industry-wide issue and we are working on new firmware but unfortunately, at this time we do not have a time frame for a release for a new firmware release. If you would like you can follow this article and you will be notified when a new firmware is posted.

  • You may not want to post this, and that is OK with me, but can I assist in some way with building the new firmware release? I have some *nix administration experience and I was planning to rebuild my firmware for my GT784WNs before the Krack vulnerability was announced. Having said that, the process would definitely be a learning experience for me, so if you say "No," I will understand completely.

  • Jim,

    We appreciate your offer and have pasted it onto the engineering team. If they accept your offer they will contact you directly.

  • OK
