VPN & Web Conferences
While it does not happen often, your VPN may be causing an issue with your conference. To see if it is, disable your VPN and test your conferences. If it works, you may need to contact your IT group or VPN Host to determine a workaround. Please note, services, like WebEx, recommend disabling VPNs.
First, you need to understand the requirements
For the best experience, you need to meet speed requirements for web conferencing:
- Zoom requirements for gallery view and/ or 720 HD video is 2.5Mbps.
- Cisco Webex requirements for High-Quality videos are 1Mbps.
Meeting the speed requirements is not enough. You must understand how your plan and the number of devices connected affect your experience. Not just that, your PC needs to meet hardware requirements.
What can cause a poor video conferencing experience?
The wrong internet plan (Speed)
If you have an internet plan of 6Mbps, 2 devices can use a web conferencing platform with minimal issues. If more people are online, for example, parents working from home, a 6Mbps connection may not be able to handle all devices. You may see issues like:
- Spinning icon on the web conferencing application
- Choppy video and audio
- Timeout errors on websites mimicking out-of-service issues
- Websites loading slower
- High ping
- Slow speeds
- An overall poor experience
Traffic on the server
Depending on the time of day and number of users, the video conference servers may not be handle the additional workload. If your internet experience is fine but you have issues when using a video conference, the issue may be with their servers.
Too many devices
If everyone in your household is online at the same time, on the wrong plan, the web conferencing experience may suffer. If you work from home and see issues when everyone is online, this could mean your internet will not support all devices connected. Now think about how that will affect distance learning. Our High Ping page has more information, and personal stories, about the affects of too many devices on the wrong plan.
