Ethernet connects a device by cable; Wi-Fi connects it by radio through a wireless access point. Many homes work best with both: wired connections for fixed equipment and Wi-Fi where people move around.
In this guide
Match the connection to the device
A desk computer, television or games console usually stays in one place. A cable can provide a consistent local connection without relying on wireless coverage at that spot. Phones and tablets need the flexibility of Wi-Fi, while a laptop may use either connection depending on where you work.
Our data and communications service can help plan permanent outlets and the cabling behind wireless access points.
Understand what each choice changes
| Question | Ethernet | Wi-Fi |
|---|---|---|
| Moving around? | Best suited to fixed locations. | Supports mobile devices within coverage. |
| Building work? | Needs a cable route and an outlet. | Access points still need power and a network connection. |
| Performance varies with? | Cable, ports, switches and device capability. | Distance, walls, interference, equipment and placement. |
| Useful starting point? | Desks, televisions and fixed network equipment. | Living areas, mobile working and handheld devices. |
Neither connection changes the internet plan delivered to your property. A faster local network cannot remove an internet-service bottleneck.
Separate coverage from internet problems
Write down where the connection is poor and whether it affects one device or several. Note whether the problem happens in the same room as the router or only farther away. If both wired and wireless connections struggle at the same time, the cause may sit elsewhere in the network or internet service.
Use consistent tasks when comparing connections. A one-off speed result is less useful than a repeatable problem, such as calls dropping at the back-room desk every afternoon.
Plan cabling before walls close
Mark the position of the fibre ONT, router, desks, televisions and intended access points on a floor plan. Include power needs and an accessible place for network equipment. Avoid putting all outlets where furniture is likely to hide them.
If you are choosing new cable, our Cat6 and Cat6A comparison explains why the installed route, connectors and testing matter alongside the category label. Consider spare routes while access is easy, without buying equipment for needs you have not defined.
Give us a connection brief
- Rooms and fixed devices that need outlets.
- Where mobile coverage currently drops.
- Video calls, large file transfers or other important tasks.
- Existing router, switch and access-point models.
- Wall, ceiling and underfloor access, plus renovation dates.

Questions about Ethernet or Wi-Fi
Will Ethernet make my internet plan faster?
It can remove a weak Wi-Fi link between a device and your router, but it does not increase the speed supplied by your internet plan.
Can I keep Wi-Fi after adding Ethernet outlets?
Yes. A mixed network is useful for fixed devices and mobile equipment, with wired links also available for suitable access points.
Show us the rooms where you work, watch and connect. We can plan practical data outlets and access-point routes around the way your household uses the network.
