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.

NOTE: If you get an error that the image is corrupt or invalid you are trying to open the image instead of following the upgrade instructions. The image file is not corrupt.

  • 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.

  • Hello,

    I currently have NCS01-1.0.12 firmware on my GT784WN. I don't need WPS. Are other issues resolved by 1.0.14 or is there an earlier version of firmware (1.0.13 ?) which I can download and install without restoring to factory defaults?

  • George,

    The .14 firmware does resolve a few other issues that were happening on the backend of the device. I would recommend updating to the .14 firmware. All firmware updates can restore your unit to defaults regardless of the version.

  • Using a GT784WN router through CenturyLink in Kingston WA. My internet has been extremely slow, often really non-functional CenturyLink seems unable to correct this except to have me disconnect power, wait, reconnect, which works for a while. Last support person suggested that fault might be with the router. Your thoughts? This upgrade something I should do?

  • Mike,

    How long ago did you get your GT784WN?

  • August 2012, from CenturyLink

  • Mike,

    I do not think Centurylink ever gave out the GT784WN. Are you sure that is the model number? The only GT series models that they gave out were the GT701, GT704. Do you know the current firmware version?

  • Check your pc and other devices in network for malware. If you are 100 percent positive no malware on any devices, have century link check the line coming to house. I work for a internet provider and more times than not, its the customers devices all fouled up with malware. Something could be hogging the bandwidth. Check your SNR of the connection in the modem. What is the speed that you are supposed to be receiving?

  • Very sure no malware, even using an Apple I have checked.
    Unable to open the upgrade. Error message "image not recognized".

  • Mike,

    Not that it should make a difference but are you using a Mac device? If so do you have a windows device you might try? Also, What are you using to extract the file from the zip folder?

  • I updated the firmware a while ago and was hoping it would resolve the periodic resetting of the unit required to get it to connect to the internet. Any ideas on how to resolve? Already ruled out the internet provider and hardwiring

  • Thomas,

    Can you tell us more about your setup and what/how you have each device connected to the GT784WN? If you don't want to share that here please give us a call.

  • I am sending the info via the email that you sent to me earlier with screen shots of the current status and system setup settings

  • I have same issue as Thomas H! My GT784WN keeps solid DSL link but drops internet connection 2-3 times per day. I have to cycle power to unit to reconnect or wait a few hours for it to do it itself! FW .13 here. I saw comment that .14 FW fixes a few other things: is this one? If not, suggestions?

  • Hello? Been a few days since I asked. Same issue as Thomas - any solution for us? random inteGT784WN issue but rather a POS company called frontier who oversold the sockets available in our area and they must kick some of us off for new people to get on line... please reply with your thoughts.

  • Mike,

    It is recommended to upgrade to the NCS01-1.0.14 firmware. If you continue to experience the connectivity issues after the upgrade please contact Actiontec Support 8884360657 for assistance while you are having the issue. Do not power cycle the modem before calling.

  • SWEET! Thank you. BUT... All my other modems and routers and repeaters have a way to save my parameters... I cannot find that on this unit. I am reluctant to update firmware when you say it will wipe all my settings I have spent HOURS or days setting up... Any chance there is a secret code ring or something that let's up make a backup copy so we can reload after your FW update wipes all settings?

  • Mike,

    The firmware upgrade is designed to keep existing settings. It does not reset to factory defaults after a upgrade. We do recommend that if you do not see the modem reboot after the upgrade that you do turn the unit off for about 5 - 10 seconds then turn it back on.

  • Experienced intermittent drops in connectivity. Called my ISP to confirm I had the setup correct. Kept having problems. As recommended on this page, I upgraded to the most recent firmware. Got the "update successfully applied message", but never got any functionality after that. Power light was solid red. Waited about 5 minutes. Tried cycling the power, then tried pressing and holding the reset button. Still a solid red light. Accessing through the browser got no response or connection. Then I called customer service and waiting forever only to speak to someone with such a strong accent I could barely understand them. After about 30 minutes on the phone with them, yup - the modem is fried (which I could have told you before I called). Now have to get a replacement. So thank you for all your expert advice and what a wonderfully lousy product it is.

  • OUCH! But the good news is you will get a brand that hopefully will stop the intermittent drops of internet! I have resisted the upgrade from .13 to .14 as the admins here seem confused how their products work; answer to me above from admin says I won't loose my programming in the nit, yet their fw upgrade says 100% I WILL loose my settings. Who do you believe? the mfgr or the mfgr?

  • mike mike,

    We have corrected the note above. The reset information was only applicable to upgrading from NCS01-1.0.2 to NCS01-1.0.8.
    We have verified the user settings will not reset when upgrading from any version after NCS01-1.0.8 firmware.

  • But what about Wayne? What are MY chances of bricking your unit by upgrading your firmware? Sounds unsafe!

  • ok, so I took my chances and updated to .14 FW. No difference on dropping internet (DSL stays up). Again, I suspect Frontier for overselling causing this so not blaming you - except your firmware should be smart enough to see DSL ON, Internet drop, and renegotiate and bring it back! No amount of pushing CONNECT button helps but power down up reboot reconnects immediately. Hint? Fix your firmware to automate this.

  • Why does the REBOOT function not work in webpage when connected to the GT784wn?
