If your bandwidth is low it can affect your audio and visuals when streaming a live course or recording.
To maximise your bandwidth, please follow the options below:
Try rebooting your router by switching it off and on again.
Ensure you are within close proximity to your router to enable a stronger WIFI signal, or view via a device which is connected directly with an Ethernet cable to your router.
Ensure no other programmes are running in the background of your device, eg downloads or several open tabs.
Reduce other devices connected to the WIFI, eg ensure no one else is using the internet at the same time as this will dilute the bandwidth.
Weather conditions can sometimes temporarily disturb bandwidth levels, as can increased usage in your local area, so it may also just be worth coming back to what you are watching later or or the following day and it will likely settle.
