GT784WN Firmware Upgrade NCS01-1.0.14

This Firmware upgrade resolves issues with enabling and disabling the WPS feature.


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 (NCS01-1.0.14) 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.

  • There's a problem with the contents of "" archive file. It does *not* contain an .IMG file as the firmware instructions say to use (top of page 2) to begin the upgrade process . It has only a file named "bcm96328GW_fs_kernel" -- so it's either the wrong file or the right file with wrong name. I also think the instructions should mention that one needs to extract the file from the .ZIP archive.


  • Martin,

    The file has been updated.

  • Admin,

    Things look much better now. Thanks!

    Observation: Since the .ZIP is about the same size as the .IMG, there doesn't seem to be much point in putting in an archive in the first place -- just one more place to make a mistake like the one that occurred. I suppose it does provide some degree of validity checking to the whole process, since ,ZIP files contain a checksum that's verified during extraction (by most ZIP archive utilities).


  • Hi, I don't use the WPS feature. Do I need to update the firmware (any problem with KRACK Vulnerability)? Thanks

  • Thig,

    The GT784WN does not support repeater mode or 802.11r FT. So it is not affected by the KRACK vulnerability. So no firmware update is required. But you will need to make sure that your wireless devices themselves are not vulnerable to the KRACK vulnerability. For that, you will need to check with the manufacture of all your wireless devices.

  • Does this firmware finally allow this modem to do annex m mode? If not when will annex m be implemented on the gt784

  • Kevin,

    This firmware does not allow the modem to do Annex M mode. Also, there are no current plans for it to be added to any future releases.
