Wireless Internet: How It Works and How to Improve Your Connection

Wireless internet: how it works and how to get the best connection

Wireless internet makes it possible to connect phones, computers, televisions and other devices to the internet without plugging each one into a network cable. It is now a familiar part of everyday life, used at home, at work and in public places. But what does “wireless internet” mean, and what can you do when the connection is slow or unreliable?

What is wireless internet?

Wireless internet is a way of accessing the internet without a direct cable running from your device to the network. The term can describe a few different technologies, but at home it usually means Wi-Fi.

A broadband router connects to your internet service provider, often through a fibre, cable or telephone-line connection. It then sends and receives data over radio waves, allowing nearby devices to get online. Wi-Fi is the wireless networking technology that links those devices to the router; it is not, by itself, the broadband service supplying the internet connection.

Wireless internet can also refer to mobile broadband. This uses a mobile network, such as 4G or 5G, to provide internet access through a phone, a dedicated router or a small portable hotspot. Some households use it instead of a fixed broadband connection, particularly where fixed-line options are limited.

Benefits of wireless internet

• Convenience: Devices can connect without individual network cables, making it easier to move around at home or work.
• Flexible access: Several devices can use the same connection, subject to the router’s capacity and the speed of the broadband service.
• Straighter set-up: Wi-Fi can reduce the need to run cables through rooms, although the router itself still needs a connection to the broadband line or mobile network.
• Portable options: Mobile broadband can provide internet access away from home, depending on network coverage and the terms of the data plan.

What affects Wi-Fi performance?

A wireless connection can be affected by the distance between a device and the router, as well as by walls, floors and other obstacles. Thick masonry, metal and underfloor heating can weaken the signal. Interference from neighbouring networks and household electronics may also affect performance.

The router is only one part of the picture. Your internet speed is influenced by the broadband package, the quality of the line or mobile signal, the number of devices using the connection and the demands of the activities taking place. Streaming video, video calls, online gaming and large downloads can all use a substantial amount of bandwidth.

It is also useful to distinguish between speed and coverage. A fast broadband package may deliver high speeds to the router, but a device at the far end of the home may still receive a weak Wi-Fi signal.

Tips for a stronger connection

1. Position the router carefully. Place it in a central, open position, raised off the floor and away from cupboards or large appliances.
2. Use the right connection for demanding devices. Where possible, connect a desktop computer, games console or television to the router with an Ethernet cable. A wired connection can be more stable than Wi-Fi.
3. Check for congestion. Disconnect devices that are not in use and pause large downloads when you need a reliable video call or online meeting.
4. Consider a mesh system or access point. These can extend coverage in larger homes, though their effectiveness depends on the building and the set-up.
5. Keep equipment up to date. Check that your router’s software and your devices’ network settings are current.
6. Test the connection in different places. Comparing results near the router and in other rooms can help identify whether the issue is with broadband speed or Wi-Fi coverage.

Staying safe online

Secure your home Wi-Fi by changing any default administrator password and using a strong password for the wireless network. Choose modern security settings where available, such as WPA2 or WPA3, and install router updates. Avoid sharing your main network password widely; some routers offer a separate guest network for visitors.

Public Wi-Fi can be useful in cafés, libraries and transport hubs, but it may not offer the same level of protection as a trusted home network. Avoid accessing sensitive services on networks you do not trust, and make sure websites use secure connections. A VPN can add privacy by encrypting traffic between your device and the VPN service, but it does not make every online activity risk-free.

Choosing a wireless internet option

When comparing broadband services, look beyond the advertised maximum speed. Check the typical speeds available at your address, any data limits, contract length, set-up costs and the provider’s customer support. If you are considering mobile broadband, check coverage where you plan to use it and find out how the data allowance works.

Wireless internet offers a convenient way to connect, but the best set-up depends on your home, your devices and how you use the internet. A suitable broadband service, a well-placed router and sensible security settings can all help provide a connection that is more reliable and easier to use.

 

9 Tips for Faster, More Reliable and Secure Wi-Fi at Home

1. Place the router centrally and in the open.
2. Keep the router away from microwaves and cordless phones.
3. Use a strong, unique Wi-Fi password.
4. Choose 5 GHz or 6 GHz for faster nearby connections.
5. Use 2.4 GHz for better range through walls.
6. Update your router’s firmware regularly.
7. Restart the router if the connection becomes unreliable.
8. Use a mesh system to improve coverage in larger homes.
9. Secure your network with WPA2 or WPA3 encryption.

Place the router centrally and in the open.

Place your router in a central, open spot in your home so its Wi-Fi signal can reach more rooms. Keep it raised off the floor and away from cupboards, thick walls and large appliances, which can weaken or block the signal.

Keep the router away from microwaves and cordless phones.

Keep your router away from microwaves and cordless phones, as these devices can interfere with the radio signals used by Wi-Fi and weaken your connection. Position the router in an open spot, with a little distance from household appliances, to help provide a more reliable signal throughout your home.

Use a strong, unique Wi-Fi password.

Use a strong, unique Wi-Fi password to help prevent strangers from accessing your network and using your internet connection. Choose a long combination of words, numbers and symbols that you do not use for other accounts, and change the router’s default password if it has not already been updated. Keep the password private and share it only with people you trust.

Choose 5 GHz or 6 GHz for faster nearby connections.

For faster connections when you’re close to your router, choose the 5 GHz or 6 GHz Wi-Fi band if your router and device support it. These bands can offer higher speeds and less interference than 2.4 GHz, making them well suited to activities such as streaming or video calls. Their signal generally does not travel as far or pass through walls as effectively, so switch to 2.4 GHz if you need better coverage in a distant room.

Use 2.4 GHz for better range through walls.

Use the 2.4 GHz Wi-Fi band when you need a stronger signal at a distance or through walls. It generally travels further and passes through obstacles better than 5 GHz, making it useful for devices in rooms far from the router. The trade-off is that it can be slower and more prone to interference, so use 5 GHz nearby when you need higher speeds.

Update your router’s firmware regularly.

Keep your router’s firmware up to date by checking for updates regularly, or enabling automatic updates if the option is available. Firmware updates can fix security vulnerabilities, improve reliability and sometimes add useful features. Follow the manufacturer’s instructions when installing an update, and avoid switching off the router until the process is complete.

Restart the router if the connection becomes unreliable.

If your wireless internet becomes unreliable, restarting the router can often resolve temporary connection problems. Switch it off at the power socket, wait for about 30 seconds, then turn it back on and allow a few minutes for it to reconnect. Your devices may need to reconnect to the Wi-Fi once the router is ready.

Use a mesh system to improve coverage in larger homes.

In a larger home, a mesh Wi-Fi system can help eliminate weak-signal areas by using several units to spread the connection throughout the property. Place the main unit near your router and position the additional units around the home, following the manufacturer’s guidance. For the best results, keep them within good range of one another and away from thick walls or large appliances.

Secure your network with WPA2 or WPA3 encryption.

Secure your wireless network by enabling WPA2 or, where supported, the newer WPA3 encryption in your router’s settings. These standards help protect data travelling between your devices and router, making it harder for unauthorised users to access your network. Use a strong, unique Wi-Fi password, and check your router’s manual or provider’s guidance if you are unsure how to update its security settings.
