Top Tips & Troubleshooting

If this is your first time using Zoom, please see our Quick Guide to Using Zoom to get started.

You can also download these tips as a .pdf document.


The biggest problem we've run into with using Zoom is weak and intermittent internet connections. Here are some tips if you encounter this issue: 

  • Quit any other programs, like browsers or mail programs, that might be using bandwidth in the background. 
  • Zoom works well on wireless all the way down to 3G, but the quality is best on a solid wired internet connection, so wire in when you can. If you are using WiFi, ensure you are getting a strong signal by moving closer to the WiFi base station. 
  • If you are sharing your internet connection with others, ask them to minimise their usage while you are on the call. 
  • Try turning off your video. 
  • Try your smartphone or tablet for the connection instead of a computer. 


Zoom works well with built-in microphones and speakers. However, if you have access to headphones or a headset with a microphone, this will improve your experience as you'll hear things more clearly and your voice will be picked up more effectively. This is not essential, but useful to know.

You may be able to 'mirror' your phone or tablet screen to your smart TV, using iPhone Screen Mirror/ Screencast/ Miracast/ Google Home app etc. Set this up and then click the link to the Zoom meeting to join the event. If necessary, re-adjust the phone for landscape/portrait orientation. Sit back and benefit from (usually superior quality) TV vision and sound. Bear in mind that, if you have your video on to ask a question, you will need to ensure that you can be seen by the other participants, so you may need to prop the device somewhere that allows this to happen. A suitably positioned laptop can also cast video chat to a smart TV, again by mirroring or physically connected with an HDMI lead.

On some devices, Zoom is only available in Speaker view, so it would be useful for you to test this in advance, if you haven't already done so.
