Symptoms
- Device shows connected to Wi-Fi or Ethernet with signal but no page loads
- Error messages mention DNS, timeout, or 'can't reach this page'
- Apps that don't rely on a browser (like some games or streaming apps) may still work while browsers fail
- Problem is the same across multiple browsers on the same device
Likely causes
- CommonDNS resolution failureThe connection to the internet may be technically fine, but without working DNS, website names can't be translated to addresses.
- CommonRouter or modem needs a restartA stuck router can maintain a local Wi-Fi connection while failing to properly pass traffic to the internet.
- PossibleRecent, brief provider outage not yet reflected in connection status indicatorsA device can still show 'connected' even during a brief upstream outage since it only checks the local link.
- PossibleBrowser-specific cache or extension issueA corrupted cache or a misbehaving extension can block all sites in one specific browser.
What to do
- Try loading a website's numeric IP address directly (searchable online) to check whether it's a DNS-specific problem versus a full outage.
- Restart the router and modem.
- Try a different browser on the same device to rule out a browser-specific issue.
- Try a different device on the same network to see if the problem is specific to one device or affects the whole network.
- Clear the browser's cache and disable extensions temporarily, especially ad blockers or VPN extensions, and retest.
- Change the device or router's DNS server to a public option like 8.8.8.8 or 1.1.1.1.
- If nothing loads on any device or browser even after these steps, treat it as a connectivity issue and follow the 'no internet connection' troubleshooting steps, including checking for an outage.
When to call a pro
Not usually needed unless the underlying cause turns out to be an ISP-side outage or line fault, in which case contact your provider.
