How to Fix Slow Wi-Fi at Home: A Troubleshooting Checklist

Slow Wi-Fi is frustrating, but it is not always your internet provider's fault. Work through this checklist in order, from the cheapest fixes to the more involved ones.

1. Test the connection properly

Run a speed test while connected to the router with an Ethernet cable, then run it again over Wi-Fi in the room where you have problems. If the cable result is also slow, the problem is your plan or your provider. If only Wi-Fi is slow, keep reading.

2. Restart the router

Unplug it for 30 seconds and plug it back in. It is a cliché because it often helps.

3. Move the router

Place it in a central, elevated, open spot. Walls, metal objects, aquariums and microwave ovens all weaken or interfere with the signal.

4. Use the right band

Most modern routers offer 2.4 GHz and 5 GHz networks, and newer ones add 6 GHz. The faster bands give better speed at shorter range, while 2.4 GHz travels farther but is slower and more crowded.

5. Reduce congestion

Many devices streaming at once can saturate your connection. Check what is using bandwidth, pause large downloads, and choose a less crowded channel in the router's settings.

6. Update the firmware

Router updates fix bugs and security problems. Check the admin page or the manufacturer's app.

7. Extend coverage

For large homes, a mesh Wi-Fi system usually works better than cheap range extenders.

8. Consider replacing an old router

If your router is many years old, a newer model can improve speed and handle more devices.
