How to Fix Weak Wi-Fi at Home: Simple Steps That Actually Help

Buffering video, dropped calls and a signal that vanishes upstairs are some of the most common home tech problems. Before you spend money, work through these steps.

1. Move your router

Routers work best in a central, open spot, raised off the floor. Walls, metal shelves, mirrors and appliances all weaken the signal. A small move can make a noticeable difference.

2. Check which band you are using

Most modern routers offer two bands. The 2.4GHz band reaches further but is slower and more crowded. The 5GHz band is faster but has a shorter range. If you are close to the router, use 5GHz. If you are further away, 2.4GHz may hold up better.

3. Restart and update

Restarting your router now and then clears small faults. Check whether it needs a firmware update too.

4. Use a cable where you can

For a desktop, games console or smart TV that stays in one place, a wired connection is usually the most reliable option. A CAT6 Ethernet cable is a simple, low-cost upgrade. If your laptop has no network port, a USB to Ethernet adapter adds one.

5. Extend the signal

If one room is a dead spot, a Wi-Fi amplifier can extend coverage there. If your router is old, replacing it with a modern dual-band router may solve the problem for the whole house.

6. Upgrade an older computer

If a desktop or older laptop struggles to hold a connection, a USB Wi-Fi adapter with an external antenna can give it a stronger, more modern connection.
