I have my airport extreme router since this past November when I got my imac. Everything has worked flawlessly on it, every device that I have that is wifi capable works without a problem. That is until I decided to put on my psp for the first time in months. My psp wasn't set to my new airport secure network and when the psp sees my network it says "not supported". What the hell is wrong here, since my ps3 (made by the same company) works fine. My crappy linkys router without security worked fine. I can't even update my psp now or use the playstation store because of this.
