Internet and home networks
Wi-Fi and the internet are not the same thing
Understand the difference between your Wi-Fi signal and your internet connection before changing settings or buying equipment.
What you will learn
You'll understand the difference between Wi-Fi and the internet, and know how to describe the problem more clearly.
Before you continue
Do not press a router reset button unless you know what it will do. A reset can remove settings that were needed for your connection.
Stop changing settings and contact your internet provider or a trusted helper if every device is offline, an outage is reported, or you are unsure which settings are safe to change.
The short version
Wi-Fi is the wireless signal inside your home. The internet is the service that connects your home to websites, apps, email, streaming and video calls.
A problem can happen in either place. Your Wi-Fi can be weak even when the internet service is working. Your internet service can also have an outage even when your phone or computer still shows a strong Wi-Fi symbol.
What Wi-Fi does
Wi-Fi connects your phone, computer, tablet, printer, TV and other devices to your router without a cable. It is local to your home or business.
Wi-Fi can slow down when you move further from the router, when thick walls or appliances block the signal, or when many devices are using it at once.
What the internet connection does
Your internet connection is the service provided through your internet provider. In many Australian homes, that service uses the nbn network, but your internet provider still manages your plan, account and support.
If the internet connection has a problem, every device in the home may be affected. You may still see the Wi-Fi symbol, because your device can still talk to the router even though the router cannot reach the internet properly.
A simple way to tell them apart
If only one room is slow, or the problem improves when you move closer to the router, start by thinking about Wi-Fi.
If every device is slow or offline, check whether your internet provider has reported an outage. You can also try one device close to the router. If nothing improves, the issue may be outside the Wi-Fi signal itself.
When a cable helps you test
If a computer or TV can connect to the router with an Ethernet cable, that test can be useful. A stable wired connection may suggest the internet service is working and the Wi-Fi signal needs attention.
Not every device has a cable port, and not every home has spare cables. This is only a helpful test if you already have the right equipment and feel comfortable using it.
What to say when asking for help
Try describing what you noticed in plain English. For example: "The Wi-Fi symbol is strong, but websites will not load", or "The laptop works near the router but not in the back room."
That kind of detail is more useful than trying to guess the technical cause.
What to expect
You can tell whether the first clues point to your Wi-Fi signal, your internet service or a device-specific problem.
