So I've just recently moved into university accommodation (college over here in Australia) and the college goes through some crappy internet provider called Everywhere Internet. Anyways, I set up my connection with them and everything, and all was working fine. Had a relatively solid (but slow as) internet connection.
However the internet dropped out one night and I couldn't get it to come back up. I decided for some reason that it'd be best to unplug and reconnect the ethernet cable (I also went into the network and sharing control panel and hit the disable button on the network I was using) and ever since then I've had no internet at all. I called the Everywhere Internet people and they said that they could see my IP address and stuff and thought that my setup was fine, therefore it must be an issue on my end. This seems to be the case because when I plug the ethernet cable into my laptop it works perfectly (currently typing this on my laptop).
So does anyone know what the hell I did wrong and how I can fix it? As I'm at university accommodation I have no access to the router or anything.
P.S. I'm using Windows 7.
