When your phone connects to WiFi but shows "no internet," the phone reached the router but the router cannot reach the wider internet, or something is blocking traffic between them. Common causes are an ISP outage, a router that needs rebooting, an unsigned captive portal, an IP address conflict, or a DNS problem.
Why this happens
- ISP or modem outage: The router is fine but the internet line into your home is down.
- Router glitch: The router gave your phone an address but lost or never established its own connection to the ISP.
- Captive portal not completed: On public or hotel WiFi you must open a browser and accept terms before internet works.
- IP conflict or bad DHCP lease: Two devices ended up with the same address, or your phone got a broken lease.
- DNS failure: The connection works but the phone cannot translate website names into addresses.
Is this normal?
It happens to everyone occasionally and usually clears with a reboot. Frequent "no internet" messages on one network point to a router, ISP, or configuration issue worth fixing.
Does it cause any problems?
No harm to the device, but apps and browsing will not load until it is resolved. Your phone may keep trying WiFi instead of switching to mobile data.
How to fix or check it
- Check another device on the same WiFi. If it also has no internet, the problem is the router or ISP, not your phone.
- Reboot your modem and router: unplug for 30 seconds, plug back in, and wait two minutes.
- On the phone, toggle WiFi off and on, or forget the network and reconnect (Android: tap the network then Forget; iPhone: Settings, WiFi, tap the "i," Forget This Network).
- For public WiFi, open a browser to trigger the sign in page. Try a plain http site if the portal does not appear.
- Change your phone DNS or set the router to use 8.8.8.8 or 1.1.1.1 to rule out DNS.
- Check the router admin page or your ISP app for an outage or a red status light.
- As a last step, reset network settings on the phone, which clears saved WiFi passwords.
Frequently asked questions
Why does one phone work but mine does not?
If other devices have internet, your phone likely has a bad DHCP lease or DNS setting. Forgetting the network and reconnecting usually fixes it.
Does "no internet" mean my WiFi password is wrong?
No. A wrong password stops you from connecting at all. "No internet" means you connected but traffic is not reaching the internet.
Should I reset network settings?
It often helps stubborn cases, but it erases saved WiFi networks and Bluetooth pairings, so try simpler steps first.
