Playstation 3 wired internet connection error; college campus.?

[Chronic]

Hi. I just recently brought my PS3 back to college, and I can't seem to get it to connect to the internet this time; it worked for months the last time I had it here.

I have a simple wired connection, from the ethernet jack straight into the back of the PS3. I changed the settings to wired, using all of the automatic settings, and it did not work. I tried turning the PS3 off and on again several times, to no avail.

Then, it randomly worked once. Today, no such luck.

The error that I recieve is 80028E06. The system finds the IP address, but quickly says there is no internet connection.

Can anyone help me out here?
