In this article, I will share some tips on how to correctly position WiFi routers to improve your home’s WiFi coverage significantly. I will also talk about a new web app from AmpliFi, called the AmpliFi Web Controller, that can help you with finding the perfect position for your WiFi equipment based on your home’s floor plan.
Factors that influence WiFi coverage
The strength of your WiFi signal is determined by four primary factors:
- Distance to the router
- Electromagnetic interference from other devices
- Obstacles between your router and wireless endpoints
- Wireless band selection (2.4 GHz vs. 5 GHz)
Your wireless router emits radio waves to cover a specific area with WiFi. The coverage area depends on your router, its antennas, and their output strength, usually measured in decibel milliwatts (dBm). The coverage claims of most router vendors are based on perfect conditions. That means the promised coverage is only achieved if the router is in direct line of sight with connected devices and without interference. But unless you live in an empty loft and position your wireless router in the dead-center of the room, you will never have perfect conditions.
All electronic devices emit electromagnetic waves that can interfere with your wireless signal if you place them too close to your wireless router. Common culprits for interference include other wireless devices, such as routers, access points, or even phones.
