What if I have the right network speed and I still have issues?

Although you may receive a speed after testing that meets the requirements, you may experience issues or receive error messages due to other factors.

Additionally, you will have access to monitor your network using the network indicator located in the upper right-hand corner of your screen. This network indicator tests your ping value response time automatically, and you can also run a test on-demand to check your download speed inside the details view. You may receive an adequate download speed, but if the response time between your computer and server is poor, you may see orange or red in the indicator.


The colors of the network indicator are defined below.

  • green.png Green = All functions of the meeting should work properly. (as long as the download speed is acceptable).
  • orange.png Orange =  Most features should function but could run into issues if lots of videos are shared.
  • red.png Red= You are probably currently experiencing issues with all functions. 

To ensure you are getting the most out of your connection, check out the tips below:

  • Try to keep your device close to your router. As you move further away from the router, you increase your chance of experiencing issues.
  • Close all other tabs, windows, and applications before the meeting, and be sure your device and browser have the most recent update installed.
  • Avoid using a public connection where there are many active users, such as coffee shops.
  • If you are experiencing network issues or poor performance, you can disable webcams being displayed to you in Virtual Classroom Settings.
  • During your session, you may see notifications to alert you of adverse network conditions and provide prompts to resolve the issue.
