Q. My Internet provider is trying to get me to pay for a faster Internet connection. I already have a 20Mbps package. Should I upgrade?

A. It depends on how many people are using the Internet. A 10Mbps connection or more is enough for the average single user or couple. Unless you have an entire family watching online video, downloading huge files or playing online games, 20Mbps is probably as high as you need to go. Learn why Internet “speed” doesn’t work the way you think, and make sure you’re getting the speed you’re already paying for.
