How to Fix WiFi Connected But No Internet — Step-by-Step Diagnosis
“Connected, no internet” is one of the most common Windows and Android network errors. The WiFi connection to the router works, but internet access is blocked somewhere between your router and the outside world. Test what you can access at instantspeedtest.net/ — if the test fails to load entirely, follow this guide.
Causes and Fixes — From Most to Least Common
| Cause | Symptom | Fix |
|---|---|---|
| ISP outage | All devices affected | Check ISP status page; wait |
| Modem needs restart | All devices affected | Power cycle modem 30 seconds |
| IP address conflict | One or some devices | Forget network, reconnect; or restart router |
| DNS not resolving | Pages don’t load but ping works | Change DNS to 1.1.1.1 or 8.8.8.8 |
| Expired DHCP lease | Single device | Disable/enable WiFi adapter |
| Corrupted TCP/IP stack (Windows) | Single Windows device | netsh winsock reset in admin CMD |
| Proxy settings misconfigured | Single device, browser-related | Remove proxy settings |
| Router firmware bug | All devices, after update | Factory reset router; reinstall firmware |
The Fastest Diagnosis — Is It Your Device or the Network?
Check a second device (phone, tablet) on the same WiFi. If both have no internet → problem is router/modem/ISP. If only one device is affected → problem is that device’s network configuration. For device-specific issues, the most effective fixes in order: (1) toggle WiFi off/on; (2) forget and rejoin the network; (3) restart the device; (4) change DNS to 1.1.1.1; (5) for Windows, run as admin in CMD: netsh winsock reset then netsh int ip reset then restart. These steps resolve 90% of single-device “connected but no internet” issues. See our WiFi disconnection guide.

Frequently Asked Questions
Why does “connected, no internet” happen randomly on Android?
Android’s “connected, no internet” detection works by pinging Google’s servers — if those pings fail (even briefly), Android shows the no-internet indicator. Common Android-specific causes: the phone connected to a guest network or captive portal that requires login; DNS resolution failing temporarily; or the phone’s DHCP lease expired. Toggle airplane mode on and off (quick full network stack reset) to resolve most temporary Android “no internet” indicators.
Can a VPN cause “connected, no internet”?
Yes — an active VPN with a failed server connection can cause exactly this symptom. The VPN routes traffic through its server; if the server is down or unreachable, all internet traffic fails while WiFi remains connected. Disable the VPN app completely and test without it. If internet works without VPN, the issue is with the VPN service or server selection.
