Compatibility Test - Instructions for Host/Presenter

In order to check if your system is able to view or run webinars with Flow, please use the following testing tools to determine the compatibility of your internet connection/network connection and computer.

Flow Connection Tester - Internet Speed Test

Please visit the following site to test your internet connection. https://diag.flowapp.com/speedtest/

What is the WebRTC Connection Test?

Flow platform uses WebRTC for media streaming. As a host/presenter, your computer, as well as the network (internet and local connection), must support WebRTC. Your internet and local network need to allow support for the following.

• All UDP ports - outbound
• WS/WSS protocol
• STUN/TURN protocols
• WebRTC blockers such as browser extensions must be disabled. In Firefox, check "about:config" and in the search box, search for "media.peerconnection.enabled". This must be set to true
• Ports such as port 80, 443, and UDP port 53

The WebRTC Connection Test performs these readiness checks for you.

What if I failed the WebRTC Test?

If you failed the WebRTC test: If you access the webinar room through a restricted/enterprise network please read this guide and forward it to support representatives of your IT Department or the Internet Service Provider. Send us a live chat/ticket if you need additional help.

What do these numbers mean?

• Download: This is your download speed, in Megabits per second (Mbps), and represents how fast you can download files and data.
  • The higher this number, the more data your connection can handle FROM our servers.
  • The Flow requires at least a 5 Mbps download speed.
  • We recommend 10 Mbps for an optimal experience
• Upload: This is your Upload speed, in Megabits per second (Mbps).
  • This only applies to Presenters and Organizers, as they will be sending data from their computers to our servers.
    
  • The higher this number, the more data your connection can send to our servers with a minimal delay.
  • Flow requires at least a 5 Mbps upload speed.

• Latency (Ping): This is the amount of time between when data packets are sent to our servers and received back from our servers, measured in milliseconds (ms).
  • The lower this number is, the less time it takes for data to be sent to and received from our servers, resulting in a better viewing and presentation experience.
  • Please refer to this chart when measuring your Latency:
    
    
    • 0-150 ms = Good
    • 151-400 ms = OK
    • 400 or greater = Poor

What do I do if I have a poor connection?

If you come below the requirements listed here for Download/Upload Speeds or Latency, you can follow these guidelines for improving your connection:

• Verify you are on the fastest, most stable network available:
  • This often means being on a wired connection instead of wireless.
  • While the speed of modern wireless networks is usually fine, sometimes they are not the most stable, due to many possibilities for signal interference which can be disruptive for a live webinar.
• Check for any software that may be filtering traffic from Flow servers:
  • These can be things like anti-virus or anti-malware applications, ad-blocking plugins in your browser, or restrictions put on your computer or network by your Internet Service Provider (ISP) or IT Department (for corporate users).
• Ensure you have the following network ports open in your personal and network firewalls (you may need help from your IT department to do this):
  • TCP 80
  • UDP 80
  • UDP 53
