linksys wireless router encryption setup

I have a linksys wireless router that I have setup encryption for. I now lost the codes…?

What is the best way to either recover the codes or reset the router?

you can reset it by unpluging it for a long time, but if you just lost the encription key, you can log in, go into security settings and look them up. you can also go into the administration settings and set the defaults.
