Tips on using Collaborate in low-bandwidth situations.

It is possible that the network connectivity of yourself or your students may be lower at times than you would normally expect. In short, the Internet may be on a ‘go slow’ from time-to-time. To mitigate the worst effects of a possible Internet slowdown, please keep everything to a minimum – and shut off everything that might be using up some of your bandwidth.

1. Close all unnecessary programs on your computer.

If you’re running a Collaborate session, the only program that needs to be running is your browser, Chrome. Shut down all the other programs on your computer, including Jabber, Webex, etc., (but remember to turn them back on afterward).

2. Close unnecessary browser tabs.

If you’re used to having loads of tabs open in your browser, then now’s the time to change this habit. You only need two tabs open to run a Collaborate session – one is NILE, the other is the Collaborate session that opened in a new tab.

3. Restrict webcam usage to a minimum.

If you don’t need to share your webcam feed with students, then don’t. And you probably don’t need them to share their webcam feeds with you either. So, if everything seems to be slowing down, then lose the video.

4. Record the session.

Even if your Internet connection is okay, your students might be struggling, so make sure that you’re recording the Collaborate session just in case.

5. If it gets really bad, turn off all your other devices, and everybody else’s too.

If the kids are gaming, or streaming Netflix, turn off their computers and give them a book to read. Turn off your phone, and everybody else’s. Turn off all other computers, other mobile devices and anything that you can think of that might be connecting to the Internet for the duration of your Collaborate session.
