Why can't I connect to the Internet on my PS3 if the signal strength is 100%?

[This Is My Real Name]

I've been trying to connect my ps3 to the Internet via wifi but it hasn't been working! My set up is a Clear Internet modem connected to a Cisco Linksys router. When I test my Internet on ps3 it says the signal is 100% but it can't even complete my Internet connection test. It either fails at PSN or the connection speeds... Please someone help me, I have no idea what to do...

try reseting your router.

Try unplugging the modem and router for 30 seconds, plug it back in, and try again, same with ur PS3. If that doesn't work, wait it out. by the next day, if it doesn't work, something must be wrong in the PS3, or with like your DNS and all that crap. Try connecting the PS3 at a friends house to determine if it;s the PS3 or router/modem.
