Ethernet port broken?

[toffa813]

So I just got to college and discovered that wifi didnt work (now I've learned that it only works with Firefox for whatever reason) so I just plugged into the ethernet port at my desk and it worked for a week or so and then it wouldn't work and I checked Network settings and it couldn't detect an ethernet cable. So I reset the PRAM and it worked... for a few hours, and now it doesn't. I don't want to have to do that every time I come back to my desk.

What should I do about this? (and any suggestions on safari/chrome not working? I posted it in another subforum on here but I got nowhere)

Anything else I can do? I'd much rather use ethernet than wifi when I'm at my desk, even though wifi isn't that bad (which I fixed btw).

I don't really know why I'd have to go to one of those, since there's one in Indy, but I don't have a car here (yet...) so I'll have to get it looked at over Thanksgiving break when I'm back home.
