Few things are as maddening as a Wi-Fi icon showing full bars with a little "No Internet" warning stuck next to it. Your device says it's connected, yet nothing loads. The good news is that this specific problem — connected to Wi-Fi but no internet access — has a short list of causes, and you can work through all of them methodically. Here's how to diagnose and fix it in 10 clear steps, starting with the fastest.
What "connected but no internet" actually means
When your device joins Wi-Fi, it's really making two separate connections: one to your router (the local network), and — through that router — one to the wider internet. "Connected but no internet" means the first link succeeded but the second failed. Your device and router are talking fine; it's the path beyond the router, or the settings governing it, that's broken. That's why the fixes below move outward: from your device, to your router, to your DNS and network configuration.
10 steps to diagnose and fix it
1. Check whether it's one device or all of them
Grab a second device — a phone, a laptop — and try to load a page on the same Wi-Fi. If everything is offline, the problem is your router or ISP (skip to Step 3). If only one device is affected, the fault is on that device (Steps 2, 6–10).
2. Restart the affected device
The oldest fix for a reason. Fully restart your phone or computer to clear temporary network glitches before touching anything more complex.
3. Power-cycle your router and modem
This resolves the majority of "no internet" cases. Unplug both your router and modem, wait a full 30 seconds, then plug the modem back in first, let it fully come online, and then the router. Give it a couple of minutes to reconnect before testing.
4. Check for an ISP outage and your cables
Look at your modem's lights — a red or missing "internet" light usually means the signal from your provider is down. Check that no cables are loose, and see whether your ISP has reported an outage in your area. If the problem is on their end, no local fix will help.
5. Forget and reconnect to the network
On your device, "forget" the Wi-Fi network, then reconnect by entering the password fresh. This clears a corrupted connection profile that can cause the "connected, no internet" state.
6. Renew your IP address
Your device may have a bad or conflicting IP address. On Windows, open Command Prompt and run ipconfig /release then ipconfig /renew. On phones, toggling Wi-Fi off and on (or Airplane mode) forces a fresh IP. Make sure your device is set to obtain its IP address automatically (DHCP).
7. Flush your DNS cache
A corrupted DNS cache can leave you connected with no ability to load sites. Clearing it forces a fresh start — our step-by-step DNS flush guide covers Windows, macOS, Android and iPhone.
8. Change your DNS server
If your ISP's DNS is failing, pages won't load even with a working connection. Switching to a fast public resolver like Cloudflare's 1.1.1.1 or Google's 8.8.8.8 often fixes it instantly. Our guide on how to change your DNS to 1.1.1.1 or 8.8.8.8 walks through it on every device.
9. Disable VPN, proxy, and check date/time
A VPN or proxy that's lost its connection can block all traffic — turn it off. Also check that your device's date and time are correct and set automatically; a wrong clock breaks secure connections and can cause exactly this symptom. Temporarily disabling third-party antivirus/firewall software helps rule it out too.
10. Reset your network settings
If nothing above works, reset the network stack. On Windows, run netsh winsock reset and netsh int ip reset in an admin Command Prompt (then restart), or use Settings → Network & Internet → Network reset. On Android and iPhone, use Reset network settings in your settings menu. This clears corrupted configuration — you'll need to re-enter Wi-Fi passwords afterward.
Verify the fix — and rule out a single-site problem
Once you're back online, confirm everything's working. If most sites load but one specific site still won't, the problem was never your connection — that site may simply be down. Run it through our live website down checker to find out, and see our guide on whether a site is down for everyone or just you to interpret the result. For a single stubborn site, our checklist on fixing a site that's down for you but not everyone picks up where this guide leaves off.
The bottom line
"Wi-Fi connected but no internet" almost always comes down to one of three layers: your device, your router/ISP, or your DNS and network settings. Work outward — restart the device, power-cycle the router, renew your IP, then flush and switch your DNS — and you'll fix the overwhelming majority of cases without any technical guesswork. Save the full network reset for last; you'll rarely need it. And once you're back online, a quick check tells you whether any lingering issue is really your connection, or just one website having a bad day.
