10 ways to improve Wi-Fi around your home
Slow Wi-Fi is not always slow broadband. These steps move from free checks to equipment changes so you can solve the real problem without buying blindly.
Fix placement and interference first, then decide whether you need better equipment.
Test near the router first
Run a speed test close to the router using a modern device. If performance is poor there, the issue may be the broadband line, router or provider rather than coverage elsewhere.
Move the router into the open
Cupboards, floors and thick walls absorb signal. A central, raised position in the open usually improves coverage more than a small change to software settings.
Keep it away from interference
Microwaves, baby monitors, cordless phone bases and some wireless accessories can compete with Wi-Fi. Add distance between the router and other electronic equipment where practical.
Use the right frequency band
Higher-frequency bands can be faster at short range, while lower-frequency bands usually travel further. Let modern devices steer automatically, but test a lower band in distant rooms when coverage is weak.
Restart and update deliberately
A restart can clear temporary problems, but repeated restarts are not a long-term fix. Check for firmware updates and note whether issues return at a particular time or under a particular load.
Disconnect forgotten devices
Old phones, smart devices and guest connections can remain on the network. Review the router’s device list, remove anything unfamiliar and update the Wi-Fi password if needed.
Use Ethernet for fixed equipment
Televisions, consoles, desktop computers and workstations often perform better on a cable. Moving heavy traffic off Wi-Fi also leaves more wireless capacity for phones and portable devices.
Place mesh units where signal is usable
A mesh point cannot repeat a strong connection if it is already sitting in a dead zone. Position it between the router and the problem room, then test again before moving farther away.
Separate coverage from capacity
Full signal bars do not guarantee enough bandwidth for many simultaneous devices. If problems appear only during busy periods, router capacity or broadband speed may be the limiting factor.
Change one thing at a time
Record a baseline, make one adjustment and repeat the same test. This simple approach prevents several changes from hiding which one actually helped.
Use the points that match your situation, then compare your options with a clearer shortlist.
