An Android phone showing “Connected, no internet” under a Wi-Fi network usually means the device has a valid Wi-Fi link but can’t reach the internet through it — a different problem than a weak signal, with a different fix.
Common Symptoms
- Wi-Fi icon shows connected but web pages and apps fail to load
- The same network works fine on other devices
- Mobile data works normally when Wi-Fi is turned off
Possible Causes
- A stale or incorrect IP/DNS configuration cached on the phone
- The router’s DHCP lease table is full or conflicting
- A captive portal (hotel/office Wi-Fi login page) hasn’t been completed
- Android’s private DNS setting pointing to an unreachable server
Before You Begin
Try opening a plain HTTP site (not HTTPS) in the browser first — if a login/captive-portal page appears, that’s the entire issue and no further troubleshooting is needed.
Method 1 — Forget and reconnect to the network
Forget the network
Settings → Wi-Fi → tap the network name → Forget.
Reconnect and re-enter the password
Search for the network again and reconnect from scratch — this clears any stale IP configuration.
Method 2 — Check Private DNS settings
Open Private DNS settings
Settings → Network & Internet → Private DNS.
Method 3 — Restart the router’s DHCP
Restart the router
If multiple devices show the same issue, restart the router — a full DHCP table is a common cause on busy networks.
If only this one phone is affected, the fix is almost always on the phone (Method 1 or 2). If every device on the network is affected, focus on the router instead.
Frequently Asked Questions
Why does this happen more on public Wi-Fi?
Public networks often use a captive portal login page that needs to be completed before real internet access is granted — this is the single most common cause on hotel/airport/office guest Wi-Fi.
Conclusion
Most “connected but no internet” cases on Android resolve with a simple forget-and-reconnect, or by completing a captive portal login that was silently missed.
