How to Fix WiFi Dead Zones in Your Home
You have a fast internet plan, but certain rooms get terrible WiFi. The problem is not your internet connection -- it is how the signal gets from your router to your devices. Here are the most effective fixes, ranked from free to investment.
Fix 1: Move Your Router (Free)
WiFi signal radiates outward from your router in all directions. If your router is in a corner of your house, half that signal goes outside. Place your router as centrally as possible, ideally elevated (on a shelf, not on the floor), and away from large metal objects, microwaves, and thick walls.
Fix 2: Update Your Router's Firmware (Free)
Router manufacturers regularly release firmware updates that improve performance and fix bugs. Log into your router's admin panel (usually 192.168.1.1 or 192.168.0.1) and check for updates. This takes 5 minutes and can noticeably improve coverage.
Fix 3: Switch to the Right WiFi Band
Modern routers broadcast on two frequencies: 2.4 GHz (longer range, slower speed) and 5 GHz (shorter range, faster speed). If you are far from the router, connecting to the 2.4 GHz band may give you a more stable connection. For devices near the router, 5 GHz provides the best speed.
Fix 4: Upgrade to a Mesh WiFi System ($200-400)
For homes over 2,000 square feet or with multiple floors, a single router often cannot cover every room. A mesh WiFi system uses multiple access points placed throughout your home, creating a seamless network with no dead zones. Top options include Google Nest WiFi, Eero, and TP-Link Deco.
Fix 5: Use Ethernet Where It Matters
For devices that do not move -- desktop computers, gaming consoles, smart TVs, streaming boxes -- a wired Ethernet connection always outperforms WiFi. You can run Ethernet cables through walls or use MoCA adapters that send network signals through your existing coaxial cables.
When the Problem Is Not WiFi
If your speed test is slow even with a wired Ethernet connection to the router, the problem is your internet plan or provider, not your WiFi. Run a speed test at speedtest.net while connected via Ethernet. If the result matches your plan speed, your internet is fine and the issue is WiFi coverage. If it is significantly below your plan speed, contact your provider.
Bottom Line
Start with router placement (free), then consider a mesh system for larger homes. For stationary devices, wired Ethernet is always the most reliable option. And make sure your underlying internet plan is fast enough before blaming your WiFi.
