PS3 Connection problems, Security?

Hello, Ive tried just about everything and still wont work. i do the custom set up, wireless, i scan the WLAN it finds the one i need (d3b6) fine. Under security, it says none, on my computer (the one it should be connecting to) ive checked to see if theres any security password or anything, it says none. so i go through the rest of it and at the end when i do my connection test, it says failed, check the security settings. Im not sure what went wrong, it doesnt HAVE SECURITY.....so if you could help thatd be very appreciated
