)
If you want to get the very best from your superfast broadband, it pays to think about how you connect. Do you go wireless with WiFi, or plug straight in with an Ethernet cable? Let’s break down Ethernet vs WiFi and show you the benefits of each, so you can choose what works best for you.

What is Ethernet?
Ethernet is a type of wired connection that use special cables, called Ethernet cables to connect you to the internet. Because it’s a physical, plug-in connection, it’s typically faster and more reliable than WiFi. That’s why it’s a popular choice for gamers, remote workers and anyone who regularly transfers large files or needs a rock-solid connection straight to their device.
Modern Ethernet cables are capable of some seriously impressive speeds. For example, Cat5e cables can support speeds of up to 1 Gbps, while Cat6a and Cat7 cables can handle 10 Gbps or more. This makes Ethernet a strong option for high demand uses where fast, stable internet is essential.
What is WiFi?
WiFi is a wireless technology that lets devices like smartphones, laptops and smart TVs connect to the internet without cables. It uses radio waves to send data between your devices and a router that’s connected to the internet, so you can get online anywhere within your WiFi range without plugging in any cables.
Your router sends a wireless signal to nearby devices. When you browse the web, stream a show or play a game, your device talks to the router over WiFi, which fetches the data and sends it back almost instantly. However, WiFi speeds and signal strength can be affected by distance, walls and interference from other devices.
WiFi comes in different generations, with newer versions offering better performance. Standards like WiFi 5 and WiFi 6 provide faster speeds, improved range and support for more connected devices, while the latest WiFi 7 helps reduce congestion for a smoother, more reliable connection.
Ethernet vs WiFi: What’s the difference?
Ethernet and WiFi both get you online, but they work in different ways. Ethernet is a wired connection, so it uses a physical cable to link your device directly to your router or network switch. WiFi, on the other hand, connects your devices wirelessly, with no cables needed.
When it comes to performance, Ethernet usually delivers a faster, more stable connection than WiFi. Because data travels straight through a cable, you’re less likely to see sudden drops in speed or connection issues. WiFi signals, however, can be affected by things like walls, distance and interference from other devices.
That said, an Ethernet cable isn’t a speed booster on its own. Your broadband package still sets the maximum speed you can get. If you’re on a package with average download speeds of 362Mbps, that’s the level of performance you should expect - plugging in with an Ethernet cable won’t push your speeds beyond what your plan allows.

Ethernet vs WiFi factors to consider
Ethernet is a wired connection that uses a physical cable to link your device to the internet, while WiFi connects devices wirelessly. Ethernet offers a more direct and stable connection, whereas WiFi is all about flexibility and convenience.
Ethernet is usually faster and more consistent than WiFi because it isn’t affected by interference or signal loss. While modern WiFi can deliver high speeds, performance can drop with distance, walls or lots of connected devices. Just remember, your broadband package still sets the maximum speed you can get.
Because it uses a direct cable, Ethernet is generally more stable and reliable than WiFi. WiFi connections can slow down or drop out if the signal is blocked or the network is busy.
WiFi lets you move freely with laptops, phones and tablets, making it the most convenient option for everyday use. Ethernet needs a cable from your router to your device, which works well for desktop setups but is less practical in shared spaces. Powerline adapters and built-in home wiring can make wired connections easier.
Ethernet offers lower latency and less lag than WiFi, making it ideal for online gaming, video calls and live streaming. For the best performance either way, you’ll still need a superfast broadband package.
Ready to get online?
Whether you are connecting via Ethernet cable or WiFi, you want to enjoy the best speeds possible, whatever you are getting up to.
