My wifi is terrible in half my house, what can I actually do about it?
You got dead zones, and that usually means your router’s hiding behind a TV or your walls are eating the signal — but the real fix is getting a second access point wired back to your main router, not just another wireless booster.
Quick things to check first
- Move your router out of a cabinet or behind a TV and put it up high in the open — walls and metal shelves kill the signal more than people think.
- Lock down your network so neighbors aren’t piggybacking and stealing your bandwidth — check your router’s admin page and make sure WPA2 or WPA3 is on with a real password.
- Unplug your router and modem for 30 seconds, then plug back in — if it’s been running for months, a reboot clears out crud.
- Stand where the signal dies and check if it’s suddenly bad on every device or just one — if it’s one phone, that phone’s the problem, not your wifi.
If that didn’t fix it
- Download a free wifi analyzer app on your phone — walk through the house and watch the signal strength drop — this tells you exactly where the dead zone starts and how bad it really is.
- While you’re in that app, check which channel your router’s on — if five neighbors are all on channel 6, switch yours to 1 or 11 in the router settings and see if it improves.
- If you have a long ethernet cable, run it temporarily from your router to the dead zone room and plug in a cheap wifi access point — if that fixes it, you know the wired backhaul approach is your permanent solution.
When to call a pro
If you’re dropping off video calls in a room that’s less than 30 feet from the router with clear line of sight, or if your signal strength is great but speed tests still show under 5 Mbps, you’ve got something deeper going on — could be interference, could be a dying router. Also, if you want ethernet jacks actually run through your walls to different rooms, that’s a job for a low-voltage electrician — they’ll punch RJ-45 drops into your wall plates clean and proper, and it’s worth the money if you’re staying in that house.
Pro tip
Next time you upgrade your router, look for WiFi 6 or better and put it as close to the center of your house as you can — not in the corner where the internet comes in. And if your house is bigger than about 2,000 square feet, plan on a wired access point from day one instead of expecting one box to cover everything.
