🔬 Methodology: Single WiFi 6 router (Netgear Nighthawk) tested in a standard 2,200 sq ft, 2-story drywall home. Speeds measured via DCSpeedTest array on 4 corner devices simultaneously to assess total house coverage.
Physics Doesn't Care About Interior Design
Most ISPs install routers in the worst possible locations: tucked in a corner of the basement, inside a TV cabinet, or behind a couch. WiFi signals are high-frequency radio waves. They act like light from a bare bulb. If you put a lamp under a couch, the room stays dark.
Test Results by Location
- 1. The TV Cabinet (Hidden behind TV, near floor): Worst. The metal in the TV acts as a shield. Speeds dropped by 70% just one room over.
- 2. The Basement Utility Room: Terrible. WiFi signals radiate outward and slightly downward like an umbrella. A basement router pushes signal into the dirt, not the second floor.
- 3. Corner Office (1st Floor): Okay. Full speed in the office, but the opposite corner of the 2nd floor became a dead zone (15 Mbps). You waste 50% of your signal broadcasting out into the street.
- 4. Central Bookshelf (1st Floor, 3ft high): Good. Covers most of the house. Corner rooms achieved 120+ Mbps.
- 5. Central Hallway (Ceiling mounted / 7ft high): Optimal. Unobstructed path over most furniture. Least interference. Enabled 400+ Mbps in every room of the house.
The 3 Rules of Router Placement
- Height is King: Place the router at least 4-5 feet off the ground. Radio waves easily pass through drywall but struggle through dense furniture, human bodies, and appliances.
- Centralize It: Imagine the router is the center of a sphere. Place it in the physical center of where humans use the internet in your home.
- Avoid The 3 H's: Heaters, Hydro (water), and Heavy Metal. Do not place near radiators, fish tanks (water absorbs 2.4GHz waves completely), or microwaves.
A $300 gaming router in a bad location will perform worse than a $50 budget router placed high and centrally.
