20.2 Speaker Connection Test
The speaker connection test in KEF Connect shows you how much network bandwidth
is available to your KEF wireless speaker system. It considers every stage of your
network by downloading a file from a random server to the speakers – from the
bandwidth provided by your internet service provider (ISP) and server traffic, all the
way to the speed of the connection between your router and speakers. The other
value shown is the ‘ping.’ This is a signal we use to check if the server is reachable and
tells us how long it takes.
