Managing the Configuration File

The configuration settings of the Dual Band Wireless-N Modem Router are stored within the modem router in a configuration file. You can back up (save) this file to your computer, restore it, or reset it to the factory default settings. From the main menu, under Maintenance, select Backup Settings.

Figure 4-8

The following sections describe the available options.

Backing Up and Restoring the Configuration

The Restore and Backup options in the Backup Settings screen let you save and retrieve a file containing your router’s configuration settings.

To save your settings, click Back Up. Your browser extracts the configuration file from the router and prompts you for a location on your computer to store the file. You can give the file a meaningful name at this time, such as comcast.cfg.

Tip: Before saving your configuration file, change the administrator password to the default, password. Then change it again after you have saved the configuration file. If you forget the password, you will need to reset the configuration to factory defaults.
