Our Netgear wifi stopped working ?

There is a tiny pin hole on the back of the router where you can fit a straightened paper clip. If put the paper clip through that hole it will push a on that can reset the router to the default settings like when you 1st purchased the router. I would recommend that you put a pword on the router so that your data isn't floating through the air unencrypted waiting for prying eyes to steal your info.
