Wi-Fi Diagnostic
"Wi-Fi isn't working" can mean a lot of different things, each with a different fix. Answer honestly and you'll land on the guide that actually matches what's happening, instead of working through steps meant for a different problem.
Do you see your Wi-Fi network in the list at all?
This points to the adapter or its driver, not the network itself. Start with our guide on no internet access, which covers checking Device Manager for the adapter and reinstalling its driver — that's the right first move when the network isn't showing up at all.
Good, the adapter itself is working. Move to the next question.
Does it connect, or fail immediately with an error?
Double-check the password first — it's the most common cause by far. If you're certain it's correct and it still won't connect, the router itself may be blocking your device (MAC filtering) or set to a Wi-Fi band your adapter doesn't support. Our Wi-Fi keeps disconnecting guide covers band-switching and driver checks that apply here too.
The connection itself works. Move to the next question — the problem is what happens after connecting.
After connecting, does it say "No internet" even though you're connected?
This is a distinct problem from the connection itself failing — you're on the network, but something's blocking actual internet access (often DNS or IP-related). Go straight to our no internet access guide, which covers the ipconfig commands and DNS checks built for exactly this.
Then the real problem is what happens next. Move to the last question.
Does the connection drop repeatedly after working fine for a while?
This is specifically what our Wi-Fi keeps disconnecting guide is built for — power management settings, driver issues, and the Network Reset option are all covered there in order of likelihood.
If none of the questions above matched what you're actually seeing, the closest starting point is our no internet access guide — it covers the broadest set of causes and is a reasonable place to start troubleshooting from scratch.
