How do I properly set up a wireless network?

I already got step-by-step instructions and set up my own wireless network; but it didn't ask for a password or anything. Instead of a flash drive, I inserted a floppy disk which should work just the same. It said it was finished but i can't find the network! All the other networks I try connecting to are secured (as expected), and I've tried several things. Now im just frustrated and still without wireless internet. What do I do now? Thank you in advance for your help!How do I properly set up a wireless network?

You do have a router, cable/dsl modem, and internet connection (non dial-up), correct?
