It's interesting that the Internet bottleneck of 2000 is now reversed. In 2000, less than 20 years ago, when I setup my first wireless router in my home, the bottleneck was the dial-up bandwidth connection to my house.
Today, the bottleneck is on the other end, at the server. High demand video websites now govern their outgoing bandwidth to our homes. In other words, they slow down how fast they serve you a movie because they have to pay for that bandwidth, and video requires a lot of it, so they use it wisely and efficiently.
Today, the speed of your internal WiFi can be a limiting factor for even a small home as multiple family members are watching videos at the same time.
