If your Android phone is connected to Wi-Fi but has no internet, test another device on the same Wi-Fi, toggle Airplane Mode, forget and reconnect to the network, turn off VPN or Private DNS, then restart the router only if more devices fail.
If mobile data works and only this Wi-Fi fails, the phone is not completely broken. The issue is usually the saved network, DNS, router profile or the Wi-Fi path.
Connected to Wi-Fi is only the first half
An Android phone can connect to Wi-Fi and still fail to open websites, WhatsApp, YouTube, Play Store or banking apps. The Wi-Fi icon only confirms that the phone joined the local wireless network. It does not prove the router has internet, DNS is working, VPN is behaving, Private DNS is reachable, or the phone is allowed through a router profile. That is why this problem feels strange: everything looks connected, but nothing loads.
The fastest fix is to compare before changing settings. If another device works on the same Wi-Fi, focus on the Android phone. If every device fails, the router, modem or provider is more likely. That one split keeps you from resetting a working network for a phone-only issue.
Quick diagnosis table
Try these fixes in order
Change one thing at a time, then test a normal website and one app before moving on.
- 01
Confirm another device works on the same Wi-Fi
Make sure the second device is really using Wi-Fi, not mobile data. If it works, the Android phone is the right place to start.
- 02
Toggle Airplane Mode
Turn Airplane Mode on for 10 seconds, then turn it off. This refreshes the wireless connection without deleting saved networks.
- 03
Forget and reconnect to Wi-Fi
Remove the saved network, reconnect and type the password again. This clears stale settings after router updates or password changes.
- 04
Turn off VPN and Private DNS
VPN and Private DNS can break one Android phone while other devices work. Set Private DNS to automatic and pause VPN for one test if allowed.
- 05
Check date, time and captive portal
Wrong time can break secure sites. Public Wi-Fi may also need a browser login before apps work.
- 06
Check router profiles
Open the router app and look for paused devices, family profiles, blocked lists or duplicate versions of the phone.
- 07
Reset network settings late
Use Android’s network reset only after the easier checks fail. It removes saved Wi-Fi and Bluetooth details, so keep it near the end.
Detailed checks
Private DNS is a common Android clue
Private DNS can improve privacy, but it can also fail silently if the DNS provider is blocked or unreachable.
- Set it back to automatic for one test.
- If internet returns, choose a different DNS provider or leave automatic on your home Wi-Fi.
Check Wi-Fi versus mobile data
If mobile data works, the phone’s apps and browser are probably fine.
- If the same apps fail on mobile data and Wi-Fi, this may be an app, account or phone-wide software issue.
- Use that comparison before blaming the router.
Watch for randomized MAC addresses
Android can use a randomized address on Wi-Fi networks.
- That may make the same phone appear as a new device in router parental controls.
- If the router app shows duplicate entries, unpause the active one and remove stale rules carefully.
Do one clean browser test
Open Chrome and type a plain website address you do not usually visit. If that works but one app still fails, the Wi-Fi fix is probably already done.
- If Chrome also fails, try opening the router login page or a captive portal page. A local router page loading while outside websites fail points toward DNS or upstream internet rather than the Wi-Fi radio.
- This keeps the test practical. You are not trying to prove every app works at once. You are trying to find which layer is broken.
When the router is blocking only this phone
Many modern router apps group devices into profiles for bedtime, school nights, security blocks or content filtering. The phone may look connected because Wi-Fi is allowed, while internet access is paused for that device.
- Look for the current Android device name, but also check for older names and duplicate entries. Some phones appear under a model number, a shortened owner name or a random device label after privacy settings change the address.
- If you find a paused entry, unpause it and test before deleting settings. Random cleanup inside the router app can make the problem harder to trace later.
Mistakes to avoid
Do not test the phone on mobile data and assume Wi-Fi is working.
Do not leave Private DNS enabled if it is the broken layer.
Do not reset the router when every other device works.
FAQ
Why is my Android connected to Wi-Fi but no internet?
The phone may be connected to the router while DNS, VPN, Private DNS, captive portal, router profiles or the provider path blocks traffic.
Test another device on the same Wi-Fi first. If it works, focus on Android settings instead of the whole router.
Can Private DNS cause no internet on Android?
Yes. If the Private DNS provider cannot be reached, apps may act offline even though Wi-Fi is connected.
Set Private DNS to automatic and test again. If that fixes it, the phone was routing names through a bad DNS path.
Should I reset network settings?
Use it after Airplane Mode, reconnecting Wi-Fi, VPN and DNS checks.
It can help stubborn Android network issues, but it removes saved Wi-Fi and Bluetooth connections.
Why does mobile data work but Wi-Fi does not?
That usually means the phone can reach the internet, but this Wi-Fi path or saved network profile is failing.
Forget the network, reconnect and check router pause rules.
When should I call my provider?
Call if several devices fail or the router/modem shows an outage.
If only the Android phone fails, provider support will usually send you back to phone settings.
Why do some Android apps work while others say offline?
That split often points to DNS, VPN, Private DNS, app cache, content filtering or a sign-in page that only some apps notice. A browser, streaming app and Play Store can behave differently because they do not all use the network in exactly the same way.
Use Chrome as the simple test. If Chrome loads normal websites but one app still fails, update or reinstall that app after checking its permissions. If Chrome fails too, stay with Wi-Fi, DNS and router profile troubleshooting.
