When it comes to the subject of your network wireless security, you might want to actually go to the Netgear homepage and read the owners manual to make sure that you cover all the steps.
If you bought the router new, and still have the documentation there should have been a "quick start guide" that came with it that simplifies the set-up steps for enabling wireless security....I've had Netgear, Linksys and Belkin routers and they all have that initial poster size set-up sheet or the equal.

Just think, there is the chance that the advice that someone here gives you may only be part of the process you need to do, continuing to leave your network open....while you feel secure. I'd go to Netgear.com and download the manual.
