(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 (126.96.36.199.14) is for the GT724WGR ONLY. It is not to be used on any other model of router or gateway. This is a 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 a 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 a NCS version installed. These types of Upgrades frequently result in a nonfunctional device.
