Wimba Troubleshooting

General Tips

  • Use a high-speed Internet connection.
  • Use a wired connection rather than wireless.
  • If a headset is to be used, ensure that it is a USB headset.
  • If a built-in (laptop) microphone is being used, avoid using Lock Talk and ensure that the Talk button is not being held down when it is not needed. This can frequenly cause a feedback look and produce an echo when others are talking.
  • Use a compatible browser.
  • Run the setup wizard before entering the classroom for the first time on any computer.
  • If a connection cannot be established to the classroom and techincal support cannot be engaged before the start of the session, use the phone simulcast number to dial into the chat. Please note that long distance charges may apply.
  • Report all technical issues to the OIT Help Desk.

          • Ensure that speaking privileges have been given to participants. This can be confirmed by the presence of a plus sign in the speaking privileges columns of the participant list. A minus sign indicates that speaking privileges​ have been disabled.
