Flow Webinar Connection Test

In order to check if your system is able to view or run webinars using flow, please use the following testing tool to determine your readiness:

Flow Connection Checker/Speed Test

Please visit the following site to test your internet connection.

https://diag.flowapp.com/speedtest/

We highly encourage you to visit this site and measure your connection before attending or presenting webinars hosted on Flow, to ensure you are on the most stable connection possible for an optimal experience.

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.
    • 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).
    • The higher this number, the more data your connection can send TO our servers.
    • This only applies to Presenters and Organizers, as they will be sending data from their computers to our servers.
    • 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 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:

      • 0-50 ms = Good
        • Video and Audio streams should playback flawlessly
      • 51-199 ms = OK
        • Video and audio streams may playback with some stuttering and a browser reload may be necessary at times to reset the connection
      • 200 or greater = Poor
        • Video and audio stream interruption is very likely. Please check your internet connection strength and try reconnecting.

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 ISP or IT Department to do this):
    • TCP 80
    • UDP 80
    • UDP 53

If you have still trouble connecting to Flow webinars, please contact the support representatives for your ISP or IT Department and let them know what's happening.
