I've had a computer running linux mint 13 for about 6 months now without any problems. Every time that I tried to connect to the internet I just used a standard ethernet port and had no problems connecting to the internet. Now this week when I moved back into my college apartment the computer suddenly will no longer connect to the internet. The computer connects to the lan no problem and I can access it my computer.
The computer is connected to the internet by a switch to a router to the modem. I know that the switch and router and modem works because every single other device (something like 12-14 devices between wifi and wired) all can get to the internet and talk to each other on the lan no problem simultaneously. There are two other computers on the switch which both have internet access.
So my question is, does anyone know what might be causing this?
