Check another device on the same Wi-Fi. If nothing works anywhere, the router or the line is the likely culprit — restart the router once and look at its lights. If only your phone is stuck, look at the phone itself: VPN, Private DNS, or forget the network and join again.

Why “connected” can still mean no internet
Your connection is a chain: phone → Wi-Fi → router → internet line → DNS → website. “Connected” only confirms the first two links. Android says “no internet” when it can’t get through the router to the outside, so the break can be at the router, on the line, at DNS, or in a setting on the phone.
Read the router lights before you call anyone
| What you see | What it usually means |
|---|---|
| Internet / WAN light off or red | The router isn’t getting a connection from the line |
| “LOS” light red or blinking (fibre) | No signal on the fibre — check the cable, then call your provider |
| “DSL” light blinking for minutes | The line can’t synchronise — check the phone cable and filter |
| Everything looks normal | The line is probably fine; look at DNS or the phone |
Names and colours vary between models, so check the label or manual of your own router. Restart it once — unplug for about 30 seconds, then give it two or three minutes. If the internet light stays off, your provider is the next call; tell them which light it is.
When only one phone is stuck
Turn off any VPN first — one that can’t connect can block everything. Then check Private DNS (Settings → Network on most Android phones) and set it to Automatic or Off. If that doesn’t help, forget the network and join again, and make sure the date and time are right; a wrong clock breaks secure websites.
On hotel or café Wi-Fi, there is often a sign-in page that didn’t open by itself. Open any website in the browser to bring it up.
Frequently asked questions
Should I reset the router to factory settings?+
Not as a first step. A restart is safe; a factory reset erases the router’s settings, and some connections need details from your provider to work again.
The internet light on my router is red. Is it my provider?+
After a restart, a red or dark internet light usually means the router isn’t getting a connection from the line. Check the cables, then contact your provider and tell them which light is off.
Why does only my phone have no internet?+
Most often a VPN, a Private DNS setting, a wrong date and time, or a saved network that needs to be forgotten and joined again.
When you need to explain it to your provider
Diagnostix360 checks the phone, the router, the internet and DNS one after another and shows which step failed — a clearer starting point than “my internet doesn’t work”.
