Broadband speed, otherwise known as bandwidth, is how much digital information can be received over your internet connection. Its measurement is displayed in megabits per second (Mbps) and the higher the speed or bandwidth, the faster your internet connection will be.
If you are experiencing audio dropouts or loss of internet radio streams you should run a broadband speed test. For more accurate results you should run the test at the time you are experiencing dropouts or stream loss, and run the test 3 or 4 times and take the average as the final result.
For uninterrupted streaming on your Pure radio your 'Download Speed' should be no less that 1Mb/s. This will ensure that any other internet usage on your network will not hinder your radio stream and provide broken or interrupted audio.
A download speed of anything less than 1Mb/s my result in interrupted or 'dropped' audio streams, especially if there is other activity happening on the same network - such as internet browsing on a computer.
