Looking for advice, PSP can't connect to Linksys Access Point

Any advice would be very helpful.

I have a Linksys WRT160n that I'm trying to connect my PSP to, and the PSP won't see the network at all. The access point works with my ps3, Wii, laptops, PCs, etc. Just not this PSP.

I have put the wireless channel to 11, and that didn't help.

Are you sure the wifi isn't broken on your psp, do you get a access point when you scan. Is your network encrypted.

If you're using WEP security, I know the Nintendo DS only supports WEP key 1...not sure about the PSP, but it's something to look in to.
