With more and more devices in our homes — phones, tablets, TVs, computers, game consoles, smart appliances and more — demanding Wi-Fi bandwidth, a reliable, speedy network is more important than ever. And if your home has a challenging layout, or you live in an older building with impenetrable walls, a single router might not cut it, leaving you with poor connectivity or dropouts. The answer is a mesh system. Rather than in a single router, a mesh system uses multiple miniature units you can place throughout your home to effectively eliminate dead zones and improve wireless internet speeds.
