To save the current configuration settings of your wireless router to a file, click **Save Configuration** next to *Save Settings To Local Hard Drive*. Depending on your browser, the file may be automatically saved to your ‘Downloads’ folder, or a ‘Save File’ or similar dialog box will appear, asking you where you wish to save the file.

To load a previously saved configuration file, click **Browse** next to *Load Settings From Local Hard Drive*. Once you have located the file (config.bin) on your hard drive, click **OK** and then click **Restore Configuration From File.**

**Note:** If you have upgraded or downgraded the firmware on your wireless router, do not load configuration files that were saved using a previous firmware version. The load will not be successful, and can damage the unit.
