High Speed Internet is considered 100Mbps and above. This is the connection into the home as opposed to the speed of the WiFi (which would typically be higher). In some countries, it is typical for 100Mbps to deliver typical speeds a little below this speed. This is still acceptable as High Speed Internet, as long as the package provided is 100Mbps+. If unsure, it's better to not tick this box as remote workers may require it.
