Xfinity, like all cable Internet providers, chooses to prioritize download speeds for their customers because most users download much more content than they upload. For example, when using Netflix to stream a film, most of the transmission of data is going from Netflix’s server down to your home network.
Test your Wi-Fi speed to see if you’re getting adequate speeds to cover all your needs for streaming TV, movies, and music.
