How to Set Up a Home Network with Ethernet

Setting up a wired home network with Ethernet is one of the best upgrades you can make for your internet connection. Whether you're working from home, gaming online, or streaming in 4K, a wired Ethernet connection delivers faster speeds, lower latency, and far greater reliability than Wi-Fi alone.

In this guide, we'll walk you through everything you need to know — from choosing the right Ethernet cables to connecting your devices — so you can build a home network that just works.

A home Ethernet network is a wired local area network (LAN) that connects your devices — computers, smart TVs, games consoles, and routers — using physical Ethernet cables rather than wireless signals. Unlike Wi-Fi, which can be disrupted by walls, interference, and distance, a wired connection provides a consistent, high-speed connection directly from your router to your device.

Many people rely entirely on Wi-Fi at home, but wired Ethernet has some significant advantages:

Faster speeds — Ethernet connections can support speeds up to 10Gbps depending on your cable category and hardware, far exceeding typical home Wi-Fi performance.

Lower latency — If you're gaming or video calling, a wired connection dramatically reduces lag and packet loss.

Greater reliability — No dropouts, no dead zones, no signal interference from neighbouring networks or household appliances.

Better security — Wired networks are harder to intercept than wireless signals.

For anyone working from home or running bandwidth-heavy tasks, switching to Ethernet — even partially — makes a noticeable difference.

Before you start, gather the following equipment:

1. A broadband router Your router is the hub of your home network. Most modern routers include at least four Ethernet ports on the back for wired connections.

2. Ethernet cables (RJ45) The most important choice you'll make. Ethernet cables come in different categories — Cat5e, Cat6, and Cat6a are the most common for home use. For most homes, Cat6 is the sweet spot: it supports speeds up to 1Gbps at distances up to 100 metres and is widely available and affordable. Browse Maplin's range of RJ45 Ethernet cables to find the right length and category for your setup.

3. A network switch (if needed) If your router doesn't have enough Ethernet ports for all your devices, a network switch lets you expand. A basic 5-port or 8-port unmanaged switch is all most homes need.

4. Ethernet adapters Many modern laptops — particularly MacBooks and ultrabooks — don't have a built-in RJ45 port. A USB-C to Ethernet adapter or a USB-A to Ethernet adapter solves this instantly. Maplin stocks a range of Ethernet adapters to suit any laptop.

Before buying cables, think about where your devices are and where your router lives. Measure the distances between rooms and add a little extra length for slack — it's always better to have too much cable than too little. Running cables along skirting boards or through wall cavities keeps things tidy.

For a home network in 2025, we recommend:

• Cat5e — Supports up to 1Gbps. Fine for basic browsing but getting dated.
• Cat6 — Supports up to 1Gbps (up to 10Gbps over short runs). The best all-round choice for home use.
• Cat6a — Supports up to 10Gbps at up to 100 metres. Future-proofed but overkill for most homes.

For most people setting up a home network, Cat6 Ethernet cable is the right choice.

If your router only has four ports and you need more, plug one Ethernet cable from any of your router's LAN ports into the "uplink" port on your network switch. This extends your network with as many extra ports as your switch provides.

Route your Ethernet cables from the router or switch to each device location. Use cable clips, trunking, or raceways to keep cables flat against walls and out of the way. Label each cable at both ends — you'll thank yourself later.

Plug one end of each Ethernet cable into your router or switch, and the other end into your device's Ethernet port. For devices without a built-in port, connect a USB-C or USB-A Ethernet adapter first.

Once connected, your device should recognise the wired connection automatically. To test it:

• On Windows, open Settings > Network & Internet > Ethernet and check the connection status.
• On Mac, open System Settings > Network and look for the Ethernet connection listed on the left.
• Run a speed test at fast.com or speedtest.net and compare your wired speeds to your previous Wi-Fi speeds.

You should see a noticeable improvement, particularly in upload speeds and ping times.

This is one of the most common questions when setting up a home network. Here's a quick guide:

For the vast majority of UK homes, a Cat6 RJ45 Ethernet cable is all you need.

• Buy slightly longer cables than you think you need — cables under tension degrade performance over time.
• Avoid tight bends — Ethernet cables shouldn't be bent at sharp angles, as this can damage the internal wiring.
• Keep cables away from power cables — running Ethernet parallel to mains electrical cables can cause interference.
• Label everything — a simple label at each end of each cable saves hours of troubleshooting later.
• Use a patch panel for larger setups — if you're cabling multiple rooms, a patch panel at a central point keeps things organised.

Do I need a router to set up a home Ethernet network? Yes — your router connects your home network to the internet and assigns IP addresses to all your devices. A network switch can expand the number of ports available, but it needs to be connected to a router to provide internet access.

How far can an Ethernet cable run? Standard Ethernet cables (Cat5e, Cat6, Cat6a) can run up to 100 metres before signal quality degrades. For most homes, this is more than enough.

Can I use Ethernet and Wi-Fi at the same time? Yes. Many people use a hybrid approach — wired Ethernet for desktops, games consoles, and smart TVs, with Wi-Fi for mobile phones and tablets. This gives you the best of both worlds.

Is Ethernet faster than Wi-Fi 6? In ideal conditions, Wi-Fi 6 can approach Gigabit speeds. However, real-world Wi-Fi performance is affected by distance, walls, and interference. A wired Ethernet connection almost always delivers more consistent speeds in practice.

What's the difference between an Ethernet cable and a LAN cable? Nothing — they're the same thing. LAN (Local Area Network) cable is simply another name for Ethernet cable.

Do smart TVs have Ethernet ports? Many smart TVs do have a built-in RJ45 Ethernet port, usually found on the back panel. Connecting your TV via Ethernet rather than Wi-Fi can improve streaming quality and reduce buffering significantly.
