My computer is saying "limited or no connectivity".

in

This means that your computer is able to detect that a cable is connected but it cannot receive a signal from the outside world. There are a few things to check before requesting help. If connection resumes normally after any of these steps there is no need to do the rest.

  1. Unplug and reconnect the ethernet cable (looks like an oversized telephone connector) on the back of your computer, then the other end at the wall jack.
  2. If you have a ethernet switch or hub connecting multiple machines in your office, unplug the cable going to your computer and move it to another port on the hub. If it works in another port then you have a bad port and it might only be a matter of time before the other ports fail.
  3. Some machines will not renew their IP address properly and have to manually be refreshed. Click "start", then "run". In the box that pops up type "command" then click "ok". A black box with white letters will pop up. In this box, type "ipconfig /release" and press "enter" or "return" on your keyboard. Wait a moment and it will tell you it is done. Next type "ipconfig /renew" and press "enter" or "return". Wait a few moments and it should tell you what your IP Address is. All campus addresses should begin with a 10.x.x.x (the x being other numbers). If it renews ok and does not have a 10.x.x.x address, please contact the helpdesk.
