I've been trying to connect my ps3 wirelessly to my router but i can't get an ip address. It used to work fine wireless but one day the internet on my computer wasn't working so i stopped using my router, but now i set it up again and the problem may have something to do with the security that i set up. I'm not sure how to disable WEP or how to change it to WPA, but i know i'm entering the correct passwords when i try to connect from my ps3. I would try entering the numbers manually, but i don't know how to.

By the way, I'm using a Netgear WGR614 router.
