How to Improve Your Home Wi-Fi Signal
Slow or unreliable Wi-Fi often comes down to router placement and settings — not your internet plan. These fixes are free and make a real difference.
Move the Router to a Central Location
~27sQuick Tip
You can extend the router's cable run or use a powerline ethernet adapter to move the router to a better location even if the modem jack is in an inconvenient spot.
Switch to 5 GHz Wi-Fi
~25sQuick Tip
Use 2.4 GHz for devices far from the router and 5 GHz for devices nearby. Smart home devices (light bulbs, thermostats) typically only work on 2.4 GHz.
Change the Wi-Fi Channel

~21sQuick Tip
Outdated router firmware is one of the most overlooked reasons for slow Wi-Fi — it is worth checking once per year at minimum.

Slow Wi-Fi at home is usually not caused by your internet plan — it is caused by how your router is positioned or configured, interference from other devices, or the distance between your devices and the router. Most Wi-Fi improvements are free and require no new hardware.
Router placement is the single most impactful factor. Routers broadcast Wi-Fi in all directions from the router's location. Placing a router in a corner, inside a closet, behind a TV cabinet, or in a basement dramatically reduces coverage in other parts of the home. A router placed centrally and elevated (on a shelf or table) covers much more of the home.
Physical obstacles reduce Wi-Fi signal significantly. The worst materials for Wi-Fi penetration: concrete, brick, and plaster walls; metal filing cabinets and appliances; and mirrors. Even placing a router behind a large fish tank or aquarium reduces signal. Glass and drywall have much less impact.
Interference from other devices is often overlooked. Baby monitors, microwave ovens, cordless phones, and neighbors' Wi-Fi networks all use the 2.4 GHz frequency band — the same as most Wi-Fi. Your router may be competing with these for airwaves. Switching to the 5 GHz band (if your router supports it) avoids most of this interference.
Before buying any new hardware, try repositioning your router and switching to 5 GHz. These free fixes often resolve Wi-Fi complaints that people assumed required a new router or mesh system.
