No Internet Connection

If your internet connection isn’t working at all, the first thing you should do is determine your IP address. Refer to the individual operating system links above for assistance with this. Below is a list of what the different IP address types signify:

  • 137.99.x.x – You are properly registered on and connected to the UConn network, and the internet should be working fine. Check for conflicting antivirus software, or try clearing your browser cache, as per the guide in our NetReg section.

  • 10.8.x.x –Your computer has not yet been registered. Refer to our NetReg section, and try to register the machine as normal.

  • 192.168.x.x –This is an address assigned by a router, not your address on the wider UConn network. If you are using a router, try connecting directly to the wall, and test your IP address again. If you are not using a router, contact us immediately, as somebody in your building may have set up their router incorrectly, causing a mass outage.

  • 169.x.x.x or 0.0.0.0 –Some part of your network connection is broken. Contact us for further support.

  • If you receive a “media disconnected” error, at least one end of your network cable can’t tell that it’s plugged in. Ensure that the connection in back of your computer is secure, and verify that you are connecting to the (black, green, or blue) jack in the wall labeled data, rather than the phone jack.
