Ethernet

Ethernet is a wired connection between a device and a router using a physical cable. It's faster, more stable, and lower latency than Wi-Fi. On most routers it's the yellow socket on the back. Plugging in over Ethernet is the easiest way to get rock solid internet for a gaming PC, work laptop, or TV streaming box.

What it actually means

Ethernet is the original way of getting a device onto a network. You take a physical cable, plug one end into the router and the other into your laptop, PC, console, or TV box, and the device is online without ever touching Wi-Fi. The yellow ports on the back of most routers are the Ethernet ports.

The reason Ethernet still matters in a wireless world is physics. Wi-Fi has to fight walls, microwaves, neighbours' routers, and every other wireless device in the house. A cable doesn't. The connection is private, the latency is lower, and the speed you pay for is the speed your device actually sees. Cable category matters too. Cat5e is fine for everyday household use up to a gigabit. Cat6 or Cat6a gives you headroom for gigabit speeds today and 10 Gbps tomorrow, which is worth thinking about if you're running a cable through a wall and don't want to redo it. Powerline adapters can carry Ethernet over your mains wiring when running a cable isn't practical, though quality varies a lot between brands.

At home

What this looks like in the house

Wi-Fi gets blamed for a lot of things that aren't really its fault. The teenager whose game keeps lagging at the worst possible moment. The 4K film that drops to a blurry mess every time someone walks past the kitchen. A five pound Ethernet cable from the router to the games console fixes most of it in under a minute. The connection stops dropping, the ping in the corner of the screen halves, and nobody has to reboot the router on a Sunday evening.

In business

What this looks like at work

In an office, Wi-Fi is fine for moving around with a laptop. Static kit shouldn't touch it. The card terminal that needs to authorise a payment in two seconds, the workstation running a video call, the printer that everyone shares, the till. Every one of those wants a cable. A flaky wireless connection on a card machine at lunchtime costs you the sale and the customer. Cabling the static stuff and keeping Wi-Fi for laptops is the simplest reliability upgrade a small office can make.

The Inspire approach

Connection Matters

How we'd handle this if you were our customer

Every router we ship with /broadband and /business-broadband comes with multiple Ethernet ports, so you can hardwire the things that matter without buying anything extra. We include a starter cable in the box and we'll tell you which devices to prioritise for Ethernet when you set the router up. For /4g-5g-home-broadband and /holiday-park-broadband the plug-and-play router also has Ethernet ports, so a TV or work laptop can stay wired even when the line itself is mobile. If you need a structured cable run across an office, we'll point you at the right local installer rather than pretending it's something we do ourselves.

Questions, answered

Frequently asked about Ethernet

Is Ethernet faster than Wi-Fi?

Yes, in almost every real world setup. A wired Ethernet connection gives you the full speed of your line with consistent latency. Wi-Fi loses speed to walls, distance, and interference from other devices, and the latency is more variable. For gaming, video calls, and 4K streaming, Ethernet is the more reliable choice.

What Ethernet cable should I buy?

Cat5e handles up to a gigabit and is fine for everyday use in most homes. Cat6 or Cat6a is the safer pick if you want headroom for faster speeds in future, and the price difference is small. For a short run between a router and a desk, any Cat5e or Cat6 cable from a reputable brand will do the job.

Do Inspire routers have Ethernet ports?

Yes. Every router we supply, whether on full fibre, 4G, or 5G home broadband, has multiple Ethernet ports on the back. You can wire in a games console, a desktop PC, a TV streaming box, or anything else you want on a stable connection. We include a cable in the box to get you started.
