This means that if you submitted your request to Residence Life on Thursday, it would get to Information Services by Friday, and you should be connected by Tuesday. Check that you're actually connected.
Most Ethernet cards have a green or orange light that flashes to indicate network activity.
If the light is off or is not flashing, then there's no connection to the network. You might try connecting it to another student's RJ45 jack, or check with the vendor who installed your network card. Your cable is defective. Try using another cable. There might be a wiring problem in the jack or wall.
