linksys wireless router security key

How do I put a password on my linksys wireless router?

I just got a wireless router, how do I password protect it? I don’t need super heavy government encryption, just like my name or something to stop people from stealing my credit card number. It’s the model wrt54gs. I can get into the settings, the only problem is that from the settings page I don’t know where to go. I found out how to set some like super heavy security, where I put in a password and it generates 4 keys, and the password is one of those 4 random kays, but I don’t want that. I want something simpler, like a word or something. how??
thanks
