Very easy – there are two ways:
- Select the "Reset to factory settings" from the opening page of the Router's web page; or
- Turn the router around and put a thin tool into the hole marked “reset.” You’ll feel a small switch – hold it down until the lights on the front of the router all blink once. Take the tool off of the switch; the lights will flash once more and the router will reset. This video shows the process in just about a minute.
