You can test your speed and latency at www.speedtest.net.

When the test completes, the results will look something like this:

Compare your results to the following minimum and recommended values.

• Recommended latency (also called 'ping'): Less than 150 milliseconds (ms)
• Minimum download speed: 0.8 Megabits per second (Mbps) - provides lower-quality video
  Recommended: 1.1 Mbps or better
• Minimum upload speed: 0.25 Mbps - provides lower-quality video to other participants
  Recommended: 0.7 Mbps or better

A wired internet connection will provide the best video quality, but you can also use a fixed-wireless, or mobile 3.5/4G data service.

• (Wireless home or office network) Try moving closer to - or at least in line-of-sight of - the Wi-Fi base station.
• (Mobile internet connection) Try moving to an area with better reception.
• Make sure that no one else in your home is using the same internet connection, and streaming video or downloading large files. This will substantially reduce the bandwidth available to make a good quality video call.
• Make sure that you don’t have more than one connection to the internet active at the same time (for example, a wired and a wireless connection running at the same time)
• Make sure that you have not used all of your internet plan’s data allocation for the month, which often results in your internet provider reducing the speed of your service.
• When you first switch on your computer after not using it for a while, it may automatically download updates. This will reduce available bandwidth. You can either wait for the updates to finish, or postpone the downloads until after you have made your video call.

• (Speakers only) If your speakers are powered separately, make sure that the power adapter is plugged in and switched on.
• Make sure that the speakers are correctly plugged into the relevant USB port or audio output jack.
• If your speakers or headphones have a separate volume control, make sure that it is set to an audible level.

• Make sure that the audio volume on your device is not on mute.
• Make sure that the device's volume is turned up to an audible level.
• Check if your audio is working by playing something else on your device. If you can't hear anything, make sure that the speakers are not disabled.

• Is it plugged in?
• If it is plugged in, is it plugged in firmly?

Tip: If your microphone uses a USB plug, unplug it, and plug it in again. This forces your computer to try and detect it again.

• Check that the volume on your device, headset microphone, or external camera is turned up and not muted.
• Note: On smartphones, the microphone will always be active, as it is also accessed by the telephone.
• Check that the microphone is enabled in your device's Sound or Audio settings.
• Make sure that the Call Screen is using the correct microphone.

Important: If you have checked all of the above, and you still can't hear anything during the microphone test, click Yes in the Video Call Setup wizard and proceed to the next step. It is possible that only the wizard has trouble playing your audio back to you, and your microphone will work fine during the actual video call. This is a known issue that occurs in rare cases.

• Is it plugged in?
• If it is plugged in, is it plugged in firmly?
  Tip: Unplug the camera, and plug it in again. This forces your computer to try and detect it again.
• You may need to update your web camera's software. Check the web camera manufacturer's website for updates to supporting software or drivers.

Can other people see anything from your side?

• No: Make sure that your camera has not been disabled in the device's settings.
• Yes: Make sure that your device is using its front camera (the one on the same side as the screen).
