77 Google Wifi
Wireless black spots are all too common, so banish those blues and boost your bars with a mesh Wi-Fi system like the superb Google Wifi. It’s ultra easy to set up, and simple to use. Just plug in multiple units around your home, with one hooked up to your internet connection, and it’ll send an intelligent net of signal through each room. Google reckons three of these inconspicuous cylinders should cover 4,500 square feet, and you can always add more later if you feel like it.
