74. Back Up Router Configuration
You can back up your router's configuration file. This is useful in cases where you want to try some new settings but then want to roll back the router's configuration to your tried-and-true settings. Having a backup of the router configuration file also provides you with the capability to get the router back into your preferred configuration if someone in your household has tampered with the router's settings.
The Backup Settings page for your router will allow you to back up the router's configuration and also restore the configuration if necessary (using the Restore command). You only need to back up the router when you change the router's configuration (such as after setting up the initial configuration). Do subsequent backups only after you change the router's configuration. I suggest that you back up changes that you make to the router's configuration only after you have determined that the new settings work. If new settings don't work, you can roll back the settings by restoring an earlier version of the router's configuration. You can save as many different backup files as you wish, which allows you to keep different versions of the router's configuration available. Most routers also provide a command that allows you to erase the router's configuration and roll back the configuration to the factory settings.
Back Up Router Configuration
If you need to reset your router and start over, your router provides an Erase or similar command that allows you to erase the router's configuration and then start again. For example, if all your users are having problems accessing the Web or other Internet services because you haven't configured service blocking or port triggering correctly and you can't figure out what you have done wrong, you might want to "reset" the router and start over. Having an earlier backup of the router's configuration (that actually worked correctly) negates the need for the Erase command because you can roll back the router to an earlier configuration; use Erase only as a last resort.
