Why Reset a Cisco Router?

Resetting a Cisco router isn’t something you’ll need to do often, but it can be a lifesaver in certain situations. For instance, if you’ve forgotten your admin password, a factory reset is often the only solution. Sometimes, a router may start behaving unpredictably, dropping connections or performing poorly. In these cases, a reset can often clear up the issue, restoring your router to its optimal performance.

Remember, though, a reset will wipe your current settings and restore your router to its default factory state. Always backup your router’s configuration before performing a reset.

How to Reset a Cisco Router

Before you start the reset process, ensure that you have a computer with a terminal emulation program like PuTTY, a console cable to connect your computer to the router, and some basic knowledge of command line interfaces.

Step 1: Connect to the Router

First, connect your computer to the router using the console cable. Open your terminal emulation program and configure it to communicate with the router.

Step 2: Enter the Commands

Once you’re connected, you’ll need to enter a series of commands to initiate the reset. Here’s a quick rundown of those commands:

  1. Type enable to enter privileged EXEC mode.
  2. Type write erase to clear the configuration.
  3. Type reload to restart the router.

After you enter these commands, your router will restart and come back up in its default factory state. Now you can reconfigure your router from scratch.
