All versions of this model were made for specific Internet Service Providers (ISP's). In the contracts we have with these ISP's they have asked us not to post ANY versions of the firmware for this modem. They did this in order to make sure that modems connected to their network are all on the same firmware. These ISP's have opted to automatically push the new firmware upgrades over the internet connection to their users once they have tested them fully for any issues on their individual networks. If you feel that your device needs a firmware upgrade we here at Actiontec ask that you contact your ISP to see if there is a newer firmware upgrade available for your device.
If you have purchased your device from one of these ISP's and are now trying to use your device with a different ISP, we do apologize but due to our contracts with these ISP's we cannot post any firmware upgrades for this device and you will have to contact your original ISP to obtain the firmware upgrade or replace your unit with retail version called the GT784WN.
