Actiontec made this model device for several different Internet Service Providers (ISPs) and we never made a Non-Customer Specific (NCS)/retail version. So at the request of those ISPs, they have asked us not to post any firmware upgrades on our support site. So you will need to contact the ISP that your model came from based off the logo on your device. Also, if you purchased this device from another location other than your current ISP please refer to ISP whose logo is on the device for help finding the most current firmware. If you are still having issues please let us know below in the comments section.
