As a participant of a Webinar, you have to verify that you are able to hear audio and view visuals before you attend a webinar. This tester checks your internet connection/local network/computer are able to receive audio and video streaming.

How to Use the Tester

1. Click here to open the testing tool
2. Click the Start Flow Capability Test to start the test

If the Test Succeeds

1. You should see the results similar to the screenshot below, when your device/network is capable. Don't worry if there was no audio. If you are able to view the video, you should be able to hear the audio during the webinar!
   
   
2. Congratulations! Your network/device is ready. You can close the page

If the Test Fails

1. Re-run the test using the same browser. If it fails, use a different browser and test it. Note down the information the tool providers you
2. Use a different internet connection if possible. If it is not possible or if it also fails, go to the step below
3. Go to the following link and run the test: https://test.webrtc.org/ and collect the test results (screenshots)
4. If you are accessing the webinar through a home internet connection, contact a Flow support agent by sending a live chat/ticket to get help if you are not accessing the webinar through a restricted internet connection. Don't forget to send us information collected in steps 1 and 3
5. If you access the webinar room through a restricted/enterprise network please read this guide and forward it along with the information collected in steps 1 and 3, to support representatives of your IT Department

Troubleshooting for Geeks

If you know your way around, check and verify the followings

1. If a browser extension is not blocking WebRTC: 
   • WebRTC blockers such as browser extensions must be disabled such as "WebRTC Control", "WebRTC LeakSheild", etc.
   • In Firefox, go to"about:config" and in the search box, search for "media.peerconnection.enabled". This must be set to true. If it is set to false, double click to enale it
2. If WS/WSS protocol is not blocked in your router/local network (mainly, port 443 and 80 outbound)
   
3. If STUN/TURN protocols are not blocked in your router
   
4. If UDP Ports are not restricted (outbound) in your router
5. If ports such as 53 are not blocked (outbound)

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
• Status

  • Good: 
  • Average: 
  • Bad: 

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
