How to Clean the Cache Out of the Router

The "cache" on your computer router is a section of the router's memory dedicated to storing instructions. As with a regular computer, if an error gets accidentally stored in this cache it could cause your router to malfunction and drop your Internet connection altogether. Clearing out the cache on a router involves using the on-board "Reset" button that was designed explicitly for this very purpose.

Locate the "Reset" button on your router. Typically this button is located on the back of the router, is red in color and is too small to press with a human finger.

Take the tip of a pencil, pen or paper clip (or any other small object) and press and hold the "Reset" button.

Wait until the lights on the front of the router turn off. Release the "Reset" button. The cache memory of the router has been cleared and the router will now turn back on.
