How to Speed Up Slow Home Wi-Fi

Slow Wi-Fi is often caused by the router's position, interference or too many devices, rather than by the internet plan itself. Before you upgrade the internet package, check the basics below. A simple speed test helps you see whether the problem is the connection to your provider or the wireless link inside your home.

Test your speed first

Connect a computer to the router with a cable and run a speed test in a browser. Then test the same computer over Wi-Fi. A large difference points to the wireless link. If the wired result is also slow, call your provider. See how to check your internet speed.

Move the router

Place the router in a central, elevated position with a clear path to the devices you use most. Keep it away from metal filing cabinets, mirrors, fish tanks and thick concrete walls.

Use the right band

Band	Speed	Range
2.4 GHz	Slower	Longer, passes through walls better
5 GHz	Faster	Shorter, weaker through walls

Use 5 GHz for devices close to the router, such as a computer in the same room. Use 2.4 GHz for devices far away or for smart home gadgets that do not need speed.

Change the Wi-Fi channel

Neighbouring networks can crowd the same channel. In the router settings, choose a less crowded channel. Channels 1, 6 and 11 are common choices on 2.4 GHz. Many routers choose automatically, so only change this if the signal is poor.

Reduce interference

Keep the router away from microwave ovens, cordless phones and baby monitors.
Turn off unused devices that use a lot of bandwidth, such as large downloads or cloud backups.
Restart the router every few months to clear the memory.

Update the router

Firmware updates can improve performance and security. See how to set up a home Wi-Fi router securely.

Consider a mesh system or access point

If the signal is weak in some rooms, a mesh system or a wired access point can extend coverage. They are often more reliable than a simple range extender.

Frequently asked questions

Are range extenders worth it?

They can help a little, but they often halve the speed for devices connected through them. A mesh system usually works better.

Should I upgrade my internet plan?

Only if the wired speed test shows the plan is slower than you pay for. Otherwise the problem is inside the house.

Use wired connections where you can

An Ethernet cable from the router to a desktop, a smart TV or a game console gives the most stable speed. Cable sets are inexpensive, and a few metres of cable can free up wireless capacity for phones and laptops. If running a cable is difficult, a powerline adapter or a mesh backhaul can be a practical alternative.

Check the devices using bandwidth

Automatic updates, cloud backups and streaming can share your connection for hours. Schedule large downloads for the night, and pause backups while you work. The router's app often shows which device uses the most data, which makes it easy to spot a problem.
