Additional troubleshooting steps


Determine if it’s a connectivity or browser specific issue.

  • If you are on campus, try using another browser or accessing other network resources, such as printers or shared drives.
  • If you can connect to other Internet sites or network resources, the problem may be with the site you are trying to access.

See if you can connect from a different area of campus or from off campus.

  • The problem may be specific to your location.

If you are connected but having problems or if you’re getting a “limited or no connectivity” message, try repairing your connection.

  • Click on Start and then Control Panel.
  • Click on Internet and Network Connections.
  • In the Internet and Network Connections window, click on the Network Connections icon toward the bottom of the window.
  • Right click on your wireless Internet icon and click Repair.

If you prefer to repair this manually, open a Command window.

  • Click Start /Run… In the Run… window, type cmd and click OK.
  • From the Command window, see if you have an IP address by entering the command: ipconfig/all
  • Then remove any IP address you may have by entering this command: ipconfig/release
  • When this command completes, try and acquire a new IP address. Enter: ipconfig/renew.

Make sure that your Internet connection can obtain an IP address dynamically.

  • Open the Control Panel and then Network Connections.
  • Right click on the wireless network icon and click on Properties.
  • In menu box that says “This connection uses the following items,” scroll to the last item and select Internet Protocol (TCP/IP).
  • With this selected, click the Properties button.
  • Make sure that the radio button which reads “Obtain an IP address automatically” is selected.
  • Make sure that the radio button which reads “Obtain DNS server address automatically” is selected.
  • Then click OK and exit.

Additional Troubleshooting Steps

  • Open an elevated command prompt (Search for cmd, right-click and choose run as administrator)
  • On the DOS window, type: ipconfig/flushdns (and hit enter)
  • On the DOS window, type: netsh int ip reset (and hit enter)
  • On the DOS window, type: netsh winsock reset (and hit enter)
  • Restart the computer and try to connect again

Update your wireless network driver.

  • If you have had your laptop for several years, the driver may be outdated.
  • The Help Desk can update the network drivers for laptops that we distribute to students and faculty.
  • If you have a personally owned laptop, please download the network driver from the manufacturer’s website and follow their instructions for installation.
