Good steps from Spyrus,

I would add to be careful if you choose the passphrase option to generate your keys. It will generate 4 keys and you will have to select the one you want to use. You cycle through the 4 keys that are generated on the page, whichever one your cursor is on or is active/highlighted/seleccted (choose your vocab) is the one the router will use. I accidentally left mine on the 4th key as i reviewed each one, and entered the first key into the laptop configs. Needless to say I had to do a little troubleshooting to figure it out. Just pay attention to detail as it is not very intuitive at first.

May seem silly but that was my experience with it, hope it helps.
