Unreliable internet is one of the most frustrating household tech problems β and one of the hardest to diagnose, because there are at least six different things that could cause it. The key is knowing how to isolate the problem layer by layer, so you are not wasting time resetting things that are not the issue.
This guide is for people who want to isolate the fault properly instead of restarting random equipment and hoping for the best. It walks through the usual causes in a practical order so you can work out whether the problem is WiFi, the modem, the NBN, the device or the setup itself.
Need help now? We can usually tell you the sensible next step quickly once we know the model, the fault and whether the issue is urgent.
Most people are trying to work out whether the dropouts are coming from the home network, the internet connection itself, or one device that is behaving differently from the rest.
The easiest way to diagnose it is to test one layer at a time. If everything drops out, start with the modem or NBN. If only one room struggles, the layout may be the real problem. If only one device disconnects, look there first.

FAQ
Questions people usually ask next
How do I know if the issue is my WiFi or my NBN?
A wired test is usually the fastest way to separate internal WiFi problems from line or provider issues.
Why does only one device keep dropping out?
That usually points to a device setting, old driver or local device fault rather than the whole home network.
Can router placement really matter?
Yes. Distance, walls, cabinets and interference all affect stability.

WiβFi keeps dropping: router, NBN or one device?
Quick answer: If every device drops at the same time, the provider/NBN path or router may be involved. If only one room struggles, coverage or interference is more likely. If only one device fails, start with that device before replacing the network.
Safe next step: Avoid factory resets until you know the login and ISP settings you would need to rebuild the connection. Rebooting is different from wiping the router configuration.
What to send us: Tell us your suburb, internet provider if known, router/mesh model, whether all devices or only some are affected, and where in the home the problem happens.
