From Consumer Reports:
- Higher is better. If you live in a two-story house, placing the router on the second floor promotes wider reach. The device’s antennas work something like an umbrella: The higher you put them, the more coverage you get below them.
- Seize the middle ground. Doors and walls are trouble, too. That means the closer the router is to the center of your home, the better off you’ll be.
- Remember the rabbit ears. You might find as many as eight antennas on some routers. They’re not there just to make the device look impressive. They really can make a difference.
- Pop your corn before the movie. If you’ve got an older, 802.11n router, devices you wouldn’t expect can interfere with the Wi-Fi signal in your home. That includes baby monitors, old cordless phones, anything running Bluetooth, even your microwave.
