I found this topic after searching on Google for a solution to this situation, but to no avail. I live in a college dorm, and I've been using their provided wireless internet service for months now. I've been able to play online with no problem. I tried connecting today, and when I run the connection test, the internet connection immediately fails after obtaining an IP. I'm inputting all the settings the way I always have.
Is this a problem on my end, or Sony's end?
Sorry but I forgot to mention, I tried the suggestion given in the topic I provided a link to, and it didn't resolve the problem.
Edit: (Just found the edit option) I figured out the problem. Disregard this thread.
