Why doesn't my PS3 online work?

Answer 1

It maybe being blocked by the Modem/router, sounds like its gaining an IP number but the modem/router ain't lettin it through

my answer:

Some information is missing from your question: have you verified whether the IP address assigned to your PS3 is valid or not? and Is your PS3 connecting wired or wireless?

IF the IP address is VALID, then for a gaming console (xbox, ps3 or wii), there are usually some ports (as well protocols for each port) that needs to be opened on the modem/router in order for your console to gain access to the internet.

On the other hand, IF the IP address is NOT valid, then you can try powercycling (means turning off your modem/router, wait for 10-15 secs. before turning it back on) your modem/router then check whether there is a corresponding ethernet light on the modem/router. If there is no ethernet light, then try another ethernet cable. Otherwise, the modem/router may be malfunctioning - in which case you can try connecting another device to your modem/router to check if the ethernet connection is not working

IF your PS3 is connected wirelessly, is it finding the wireless network name on your modem/router? If the IP address is NOT valid, then its a simple password issue. Some PS3 does not support 128-bit encryption (might be a firmware issue on the PS3) - in which case use 64-bit. If IP address is valid, then its time to contact PS3 to get the port numbers and the protocols.

Answer 2

Make sure you are connected to the internet.

Occasionally the network servers will be down for maintenance. After the outages of April 20- May14, 2011, users were required to reset their passwords and download new security software. Your connection may require alteration.

(to check the status of the network, see the related link)
