No Network Connectivity on Classroom Computers

Computer sign-in, web access, email, Blackboard and network drive access require a network connection. An inactive or unavailable network connection will affect all services and sites — not just one. A potential network issue may be identified at sign-in by an error message such as Domain Controller Not Found.

Solution

1. Try multiple common websites (towson.edu, google.com, cnn.com, etc.). If one site works while another doesn't, this indicates an issue with a particular site and not the network connection.
2. If no websites will load, restart the web browser and try again.
3. Restart the computer.
   • Windows: Sign out. From the Sign In screen, click the power icon in the lower right and select Restart.
   • Apple: Click the Apple menu icon and select Restart.
   • If these restart attempts do not work, hold down the computer's power button for a hard reset.
4. Check the network cable connection at the wall or floor box near the lectern; a loose or unplugged cable will affect network connectivity. In some classrooms, these connections may be concealed beneath the lectern. If this is the case, move on to the next step below; do not attempt to move the lectern.
5. If the above steps fail to resolve the issue, report it by calling 4-TECH at 410-704-8324 or using the CCLT chat service. Widespread network outages or local issues may take some time to resolve; plan to continue teaching without online resources.

Workarounds

1. Media players and document cameras function without network access; use these to play video content or display textbook pages.
2. If wireless internet has not been affected, connect a laptop to access online resources. Select the Laptop or Auxiliary HDMI input source from the control panel.
