WiFi Speed vs Distance: Range & Signal Loss Data 2026
By SpeedTestHQ Research · Updated April 28, 2026
WiFi speed degrades with distance and through walls. Here is the measured data for WiFi 5, WiFi 6, and WiFi 6E — and what it means for your home setup.
How WiFi speed degrades with distance
WiFi signal strength falls off with distance due to two factors: free-space path loss (signal spreading in all directions) and physical obstructions (walls, floors, furniture). The relationship is not linear — signal loss accelerates at greater distances and through materials like concrete, brick, and metal.
| Distance from Router | WiFi 5 (AC) | WiFi 6 (AX) | WiFi 6E (6 GHz) | Notes |
|---|---|---|---|---|
| 10 ft / 3 m | 480 Mbps | 750 Mbps | 1,800 Mbps | Near-maximum throughput |
| 30 ft / 9 m | 340 Mbps | 600 Mbps | 900 Mbps | Slight signal loss |
| 50 ft / 15 m | 210 Mbps | 420 Mbps | 300 Mbps | 6E degrades faster through walls |
| 75 ft / 23 m | 120 Mbps | 280 Mbps | 80 Mbps | 6E struggles through 2+ walls |
| 100 ft / 30 m | 55 Mbps | 160 Mbps | 12 Mbps | 6E often unusable at this range |
| 150 ft / 46 m | 8 Mbps | 60 Mbps | ~0 Mbps | Connection marginal on WiFi 5 |
Tests conducted in a residential environment with 1–2 drywall walls between router and device. Open-space results will be 20–40% higher at long distances. Results are typical wired-equivalent throughput, not maximum PHY rate.
How wall materials affect WiFi range
- Drywall: ~3 dB loss per wall — manageable; most homes use this
- Wood/glass: 4–6 dB loss — minor impact
- Brick: 10–15 dB loss — significant; one brick wall can halve your speed
- Concrete/reinforced: 15–25 dB loss — severe; a single concrete floor often kills the 6 GHz band entirely
- Metal (foil insulation, ductwork): 25–35 dB loss — WiFi signal effectively blocked
WiFi 5 vs WiFi 6 vs WiFi 6E: which has better range?
WiFi 6 (2.4/5 GHz) has better range than WiFi 5 thanks to OFDMA and BSS coloring, which reduce interference and improve efficiency at weak signal levels. In practice, WiFi 6 maintains usable speeds about 30–40% further than WiFi 5.
WiFi 6E (6 GHz) offers dramatically higher speeds at close range but has significantly worse wall penetration than 5 GHz. The 6 GHz band is ideal for open-plan offices and living rooms with direct line-of-sight to the router, but performs poorly through multiple walls.
How to extend your WiFi range
- Place your router centrally, not in a corner or closet — central placement doubles effective coverage area
- Elevate the router: floor-level routers lose significant signal through the floor
- Use a mesh WiFi system for large homes — a single router cannot reliably cover more than ~2,000 sq ft through walls
- Use a WiFi extender as a cheaper alternative if you only need to cover one dead zone
- For gaming or work-critical devices, use an Ethernet cable — it eliminates all wireless variability
Key findings
- Speed halves roughly every 15–20 feet through drywall: WiFi 5 drops from ~800 Mbps at 10 ft to ~200 Mbps at 50 ft through two drywall walls — a 75% reduction. WiFi 6 degrades more slowly due to better signal processing, but the physical attenuation curve is similar.
- Wall material matters more than distance: A single brick wall at 15 ft causes more speed loss than 50 ft of open air. Homes with concrete floors, tile bathrooms, or foil-backed insulation see dramatic drops that distance alone cannot explain.
- 6 GHz (WiFi 6E/7) has the worst wall penetration: WiFi 6E delivers the fastest same-room speeds but loses effectiveness through a single concrete wall or floor. Its practical range advantage over 5 GHz is limited to rooms with clear line-of-sight paths.
- Router placement has more impact than router generation: Moving a router from a corner closet to a central open shelf can improve far-room speeds by 2–4× — a larger gain than upgrading from WiFi 5 to WiFi 6 with poor placement.
Methodology
WiFi speed-by-distance data is derived from SpeedTestHQ tests paired with user-reported router distance estimates, segmented by WiFi generation and reported frequency band, over the 90-day period ending April 2026. Wall material impact values are modeled from RF propagation loss coefficients (dB per obstacle type) calibrated against measured test distributions. Distance ranges represent typical residential deployments; outdoor or line-of-sight performance will exceed these figures. Tests from known Wi-Fi extenders or mesh satellite nodes are excluded to isolate single-router performance.
These figures are planning ranges, not a guarantee for every address or device. Your result can change with router placement, local interference, server distance, ISP routing, plan tier, firmware, client hardware, and time of day. For your own connection, run a wired speed test and compare it with Wi-Fi and peak-hour tests.
Frequently Asked Questions
How far does WiFi reach?
A typical single router covers 100–150 ft (30–46 m) with degrading speed. Open floor plans with no walls may reach 200+ ft. Walls, especially concrete or brick, significantly reduce this range. WiFi 6 extends effective range by 30–40% over WiFi 5.
Why is my WiFi slow far from the router?
WiFi signal loses strength with distance and through physical obstructions. At weak signal levels, the router and device negotiate a lower data rate to maintain the connection — this is why speed drops sharply at distance even though you still have a connection. Use a mesh node or wired connection for distant devices.
Does WiFi 6 have better range than WiFi 5?
Yes — WiFi 6 maintains usable speeds at greater distances due to improved modulation efficiency and interference handling. However, the 6 GHz band introduced in WiFi 6E has worse wall penetration than 5 GHz.
What is the maximum distance for WiFi?
Under ideal open-air conditions, 802.11ac/ax can maintain a connection at 300+ ft. In real homes, effective high-speed coverage typically ends at 100–150 ft through 2–3 walls.
