Why Your WiFi Is Slow in Certain Rooms (And How to Fix It)

You're paying for fast internet but getting a slow, unreliable signal in your home office, bedroom, or backyard. Here's why it happens and how to fix it for good.

Why WiFi degrades over distance

WiFi signal strength decreases with distance and weakens further with every wall, floor, and physical obstacle it passes through. Concrete walls, brick, metal studs, and even large mirrors can dramatically reduce signal strength.

Common causes of dead zones

Router placement: Most people put their router where the ISP installed it — often in a corner or closet. The router should be centrally located, elevated, and away from obstacles. This single change solves the problem for many homes.

Router age: A router from 2015 or earlier likely lacks the range and capacity for today's homes. Modern WiFi 6 routers handle more devices more efficiently.

Band selection: 2.4 GHz has better range but lower speed; 5 GHz has higher speed but shorter range. Devices that auto-select between bands sometimes make poor choices.

What actually works

For most homes (under 2,500 sq ft): Router repositioning + a quality WiFi 6 router resolves the majority of dead zone complaints.

For larger homes or thick walls: A mesh network system (Eero, Google Nest Wifi, TP-Link Deco) with 2–3 nodes is the most reliable long-term solution. Properly placed mesh nodes eliminate dead zones entirely.
