Troubleshooting Tips for
Big Blue Button is one of the ways an IA students can participate in a live chat with his or her teacher and fellow students. Having trouble getting started? Always check with your teacher first, then read on for some common issues and ways to get up and conferencing!
Can’t find your conference?
BBB conferences are only visible when they are open. If the conference hasn’t begun or is already done, the conference link won’t work.
Is Flash enabled? If you’re using the Google Chrome web browser:
- Open Chrome, type: chrome://plugins in the address bar
- Under the Adobe Flash Player listing, click a check in the box “Always allowed to run”
- Close chrome windows and reopen
Do I have enough bandwidth on my internet connection? To check, visit: http://www.speedtest.net/
- 0.5 mbits/sec upstream minimum
- 1 mbits/sec download minimum
- Not enough bandwidth? Contact your teacher for alternative ways to connect.
Is wired connection better than wireless? YES.
A user may have a good experience with wireless internet, but if others hear their audio as broken or choppy, that user can either move closer to the wireless base station, try a different wireless network, or (best) connect directly to a wired connection.
Using public WiFi is not always best. It may be OK for surfing the web, but the latency and other loss might be insufficient for real-time transmission of audio or video.
Other Commonly Experienced Issues and Tips from BBB Support
Users on Chrome get randomly disconnected
When running BigBlueButton in Google Chrome, if the user is connected to both wired and wireless at the same time, and the wireless state changes (such as disconnecting or switching between wireless networks), Chrome sends a network change event to BigBlueButton and drops the user’s connection.
If this occurs, the solution is to either disable wireless networking while using BigBlueButton or switch to FireFox. FireFox uses Adobe Flash Plugin whereas Google Chrome bundles the flash plugin within the browser.
Users on windows 7 get disconnected after a minute
The default configuration of Windows 7 (and Vista) does “ICMPv6 Router Solicitation” while running the Flash client. Some routers discard the Teredo packets, thereby causing the BigBlueButton client to disconnect at regular intervals. One solution is to disable Teredo packets in the client by entering the following:
netsh interface ipv6 set teredo disable
To run this command, you’ll need to enter ‘cmd’ in the program search field (available when you click the start menu). When you type ‘cmd’, you’ll see the ‘command prompt’ appear. Right-click and choose “Run as Administrator”.
