Is Flash installed? If you’re using the Google Chrome web browser:
- Open Chrome, type: chrome://components in the address bar
- Check to see if Adobe Flash Player is on the list. You may also click the “check for updates” box at this time.
If Flash isn’t on the list, you can download and install it:
- On your computer, open Chrome.
- Go to http://www.adobe.com/go/chrome.
- Under “Step 1,” select your computer’s operating system.
- Under “Step 2,” choose the option that lists “PPAPI.”
- Click Download now, and follow the steps to install Adobe Flash Player.
- Close all browser windows and restart for the new settings to take effect.
To configure Flash settings in Chrome:
- At the top right, click Settings
- At the bottom, click Show advanced settings.
- Under “Privacy,” click Content settings.
- Under “Flash,” choose “Ask first before running Flash (recommended)” or “Allow sites to run Flash”
- At the bottom, click Done.
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”.
