If you are experiencing issues like connectivity problems, connection drops etc with your Belkin N+ router, then a hard reset may be the way to go. Here is how to do a hard reset.
Look for the Reset button of your router. The location of the Reset button may vary depending on the model of your router. In this example, the button is at the back panel of the router.
While the router is powered ON, press and hold the Reset button for 15 seconds.
Wait for one (1) minute for the router to restart.
Your Belkin router has now been reset to its factory default settings. Take note that resetting the router will also set its language back to English or to the language your web browser is using.
