PSN Access

I hope this is the right place for this question. If not, I apologize in advance.

I've had a PS3 since December, and I've never had a problem going online with it, until earlier this week. I can browse the internet on my PS3 but I can't sign in with my user account. I constantly get disconnected from the PSN. I've tried a lot of different things so far, and here's what I've learned:

I get the same behavior whether I use a wired connection directly from my cable modem or access the internet through my wireless router. I wanted to eliminate router issues from the equation, and I still can't connect even when wired directly to the cable modem, but I think it's safe to say it's not a problem internal to my router.

I've attempted to disable the media server service since that apparently borked some people, but this didn't work. Same issue.

I'm confused by the fact that I can access the internet through the PS3 but not the PSN. Is it possible that my ISP suddenly blocked the ports I need to use? Right now that's the only thing I can think of.

Its very unlikely that your ISP would just block the psn ports all of a sudden, have you tried putting your ps3 in your routers DMZ? (browsing the web should theoretically just use TCP while the PSN network uses TCP and UDP, so its not that strange to be able to do one and not the other.

If a direct connection to the modem doesn't work, then the router's DMZ wouldn't do anything. Go here and:

Click 'proceed'.
Click 'user specified custom port probe'.
Enter '3478,3479,3658,5523,10070-10080' in the field and click the above button again.

Those are the most common ports that PSN uses from what I gathered. See if they're listed as open or closed. I don't use PSN, so I don't know if it would even matter, but it's a start I suppose. And put your PS3 on DMZ, since I assume you'll need the router to use the computer to run the port scan.

Also, are you really from South Korea? If PSN lets you select which server to connection to by region, make sure that you're connecting to Asia or whatever region you would be listed in. You might be trying to connect to the US server or something.

Thanks, I'll try that. I have a list of all the various ports that the PS3 uses and the corresponding protocols.

I live in South Korea, but I'm not from here. I didn't consider that Sony may have started blocking Korean internet traffic to their US services. I picked up the PS3 when I was back home in the US last December, and never had a problem with the connection until earlier this week.

I don't know if the DMZ is really necessary, because UPnP never gave me issues before. I'll go ahead and use it though, because logging in never gave me issues before either.

I found another person online with this issue over at Gamer411. It's the only other report I've seen of it online so far, and it affected him right around the same time as me.

Problem solved. Turns out I have a crap ISP. I took my PS3 to our other house and I connected immediately.
