Why Your Wi-Fi Drops in Certain Rooms (and How to Fix It)

You've probably experienced it. Your video call is fine in the kitchen but freezes in the bedroom. Your streaming stalls in the basement. The signal is strong in one part of the house and nonexistent in another. Wi-Fi dead zones are frustrating, but they usually have straightforward causes and fixes.

The most common culprit is distance. Wi-Fi signals get weaker the farther they travel from the router, and a single router can only cover so much space. In a larger or multi-level home, one central device often isn't enough, no matter how expensive it is.

Building materials are the next big factor.

Wood-framed walls let signals through fairly easily, but stone, brick, concrete, metal, and log construction can block or weaken them. Fireplaces, large mirrors, metal ductwork, and even water pipes and aquariums can get in the way. Many Montana homes have a lot of these materials, which makes coverage a special challenge.

Router placement plays a bigger role than most people realize. Routers tucked into a basement corner, a cabinet, or behind a TV often perform poorly. The best spot is usually central and elevated, out in the open, but that isn't always where the internet line comes into the house.

Interference can also be to blame. Other networks, cordless phones, microwaves, and Bluetooth devices can compete for the same airwaves, and a crowded network with dozens of connected devices can slow to a crawl. Older routers struggle to handle the number of devices in the average modern home, which often includes phones, laptops, TVs, cameras, thermostats, and speakers.

The fix depends on the cause, but the most effective solution is usually to add more access points.

Instead of trying to push one signal through the whole house, you spread several access points around so each one covers a smaller area. Connecting them with ethernet cable, called a wired backhaul, gives the best performance because the access points don't have to share Wi-Fi bandwidth just to talk to each other.

Where cable isn't practical, a mesh system, like Eero, can extend coverage wirelessly. Mesh works well in many homes, especially when the nodes are placed carefully. Professional-grade equipment, such as Alta Labs, offers more control and reliability for larger or more demanding homes and businesses.

A few simple steps can help in the meantime. Move the router to a more open location. Update its firmware. Restart it occasionally. Cut down the number of devices using the network at once if you can. If problems persist, a site survey by a professional can map your home's signal and pinpoint exactly where coverage falls short, so you can fix the problem for good rather than guess.
