A 100 megabits-per-second download speed allows you to download a high-definition movie in under five minutes. As of 2015, this is a typical speed for a fast fiber broadband connection. To support this speed over Wi-Fi, a wireless router must support the 802.11n or newer wireless standard.
The definition of a fast connection varies between users. Some users consider a Wi-Fi connection speed as low as 5Mbps to be fast. A 5Mbps connection can download a typical song in a few seconds.
The United States has an average broadband connection speed of 11.1Mbps, which is sufficient for streaming high-quality video, although the Netflix streaming service recommends a 25Mbps connection for streaming at "Ultra HD" settings.
