Step 1: Locate the Reset button at the back or bottom of your router. Using a pen or a paper clip press and hold the Reset button for 10 seconds. For router models such as the Linksys Wireless-B and G routers press and hold the Reset button for 30 seconds.
QUICK TIP: Observe the Power LED on the router while pressing the button. It should blink or flash as an indication that the router is properly resetting.
Step 2: Unplug the router from the power outlet for 30 seconds. Plug it back and wait for the Power LED to be solid.
IMPORTANT: For the newly-released Linksys Wi-Fi Routers unplugging the device from the outlet is no longer required.
