A sluggish wireless network is frustrating. It's no fun when an exciting movie suddenly starts buffering or an important Internet video call breaks up.
A few years ago, families didn't put much demand on routers. All they did was browse the Web and read email. The average home had one or two PCs.
Today, a family might have several computers, a wireless printer, a game console, a streaming video gadget and a variety of smartphones and tablets. A router can really bog down when everyone wants to surf, download files, play online games and stream music and movies at the same time.
