Quick Answer
If your Android phone or iPhone says it is connected to Wi-Fi but websites and apps have no internet, first test another device on the same Wi-Fi network. If several devices also cannot get online, focus on the router, modem, or ISP. If only your phone is affected, reconnect the Wi-Fi network and check phone-side network settings. Router DNS or DHCP failure is one possible cause, but the Wi-Fi icon alone does not confirm it.

Google’s current Pixel troubleshooting guidance specifically recommends comparing another device on the same Wi-Fi and testing the phone on another Wi-Fi network to determine whether the problem follows the phone, the network, or the internet connection.
1-Minute Safe Checks
Before changing DNS addresses, assigning a static IP, or resetting network settings:
- Turn Wi-Fi off and back on.
- Restart the phone.
- Open two unrelated websites and another internet-based app.
- Test another phone, computer, or tablet on the same Wi-Fi.
- If possible, test your phone on another trusted Wi-Fi network.
If every device on your Wi-Fi has lost internet access, avoid repeatedly changing settings on the phone. The router, modem, internet service, or network configuration should be checked first. Google, Apple, and Samsung all use device-versus-network comparison and router restarts as early troubleshooting steps.
Fix 1: Determine Whether the Phone or Wi-Fi Network Is Affected
DIAGNOSTIC TEST
Use This When
Use this before resetting anything.
Why It May Help
A phone can remain successfully associated with a Wi-Fi router even when the router itself does not have a working internet connection. The same message can also appear when only one phone has a network configuration problem.
Testing another device separates these situations.
Steps
- Keep your phone connected to the affected Wi-Fi network.
- Open a normal website.
- Open another unrelated website or internet-based app.
- Connect another phone, tablet, or computer to the same Wi-Fi.
- Test internet access on that device.
- If available, connect your original phone to another trusted Wi-Fi network.
- Compare the results.
Expected Result
You should be able to determine whether the failure follows the Wi-Fi network or the phone.
What the Result Means
- Several devices have no internet on the same Wi-Fi: The router, modem, ISP connection, or network configuration becomes more relevant.
- Other devices work but your phone does not: Continue with phone-side troubleshooting.
- Your phone works normally on another Wi-Fi network: The original network becomes the main area to investigate.
- Your phone fails on several unrelated Wi-Fi networks: A device setting, VPN, software issue, or other phone-side cause becomes more plausible.
This test narrows the problem but does not identify a specific failed component by itself.
Fix 2: Check for a Public Wi-Fi Login Page
CONDITIONAL STEP
Use This When
Use this at hotels, airports, cafés, schools, hospitals, malls, and other public or managed Wi-Fi networks.
Why It May Help
Some networks allow your phone to connect to Wi-Fi before they grant internet access. You may need to accept terms, enter a room number or account, or complete another authorization step.
Both Google and Apple document this captive-network behavior.
Steps
- Connect to the Wi-Fi network.
- Open your normal web browser.
- Open a new webpage.
- Look for a network sign-in notification or login page.
- Complete the required authorization or accept the network terms.
- Return to your browser and test another website.
On an iPhone or iPad, Apple also recommends selecting the Wi-Fi network and waiting for its login screen when using a captive network.
Expected Result
Internet access should begin after the network accepts your authorization.
What the Result Means
- If the login page never appears or rejects valid credentials, the network administrator may need to help.
- Do not reset your entire phone because a hotel, school, or business Wi-Fi network requires authorization.
Fix 3: Restart the Router and Modem
OFFICIALLY DOCUMENTED STEP
Use This When
Use this when several devices on the same Wi-Fi network have no internet or the problem began suddenly.
Why It May Help
Restarting network equipment can re-establish the connection between the modem, router, and ISP without changing the router configuration.
Google Pixel Help, Apple Support, and Samsung Support all include restarting networking equipment in their Wi-Fi troubleshooting guidance.
Steps
If you own or manage the network:
- Turn off or unplug the router.
- If a separate modem is present, turn it off or unplug it as well.
- Wait at least 15 seconds.
- Reconnect the modem first if it is a separate device.
- Allow its normal status lights to return.
- Reconnect or restart the Wi-Fi router.
- Allow the router to finish starting.
- Reconnect your phone.
- Test several websites.
Do not press a recessed Reset or Factory Reset button. That is different from simply restarting the router and can erase its configuration.
Expected Result
The router should reconnect to its upstream internet service and your phone should regain internet access.
What the Result Means
- If every device begins working again, a temporary router, modem, or upstream connection problem may have been involved.
- If every device remains offline, check your ISP’s service information or contact the ISP.
- If other devices recover but your phone does not, continue with phone-side steps.
A successful restart does not prove that DNS, DHCP, the modem, or any specific router component caused the problem.
Fix 4: Forget the Wi-Fi Network and Reconnect
OFFICIALLY DOCUMENTED STEP
Use This When
Use this when other devices can access the internet through the same Wi-Fi but your phone cannot.
Why It May Help
Forgetting the network removes its saved connection information from the phone. Reconnecting creates a fresh Wi-Fi connection using the current network configuration.
Google, Samsung, and Apple provide procedures for removing or forgetting saved Wi-Fi networks.
Android or Google Pixel
Menu names vary between Android manufacturers.
On current Pixel guidance:
- Open Settings.
- Tap Network & internet.
- Tap Internet.
- Open Saved networks if necessary.
- Select the affected network.
- Tap Forget.
- Return to the Wi-Fi network list.
- Select the network again.
- Enter the correct Wi-Fi password.
- Test internet access.
Samsung Galaxy
On supported Galaxy devices:
- Open Settings.
- Tap Connections.
- Tap Wi-Fi.
- Tap the settings icon beside the network.
- Tap Forget.
- Select the network again.
- Enter its password and reconnect.
iPhone or iPad
Open Settings → Wi-Fi, open the affected network’s information page, and use Forget This Network when available. You will need the Wi-Fi password to reconnect. Apple notes that forgetting a network can also affect devices sharing Wi-Fi credentials through iCloud Keychain.
Expected Result
The phone should reconnect using newly created network information.
What the Result Means
- If internet access returns, the phone’s saved Wi-Fi configuration may have contributed.
- If the problem remains on only this network, continue with the router/DNS/DHCP checks.
- If the phone fails on several unrelated networks, continue with phone-side troubleshooting.
Fix 5: Check Router DNS or DHCP Only When the Pattern Fits
DIAGNOSTIC TEST
Use This When
Check router-side DNS or DHCP configuration when:
- Several devices connect to the same Wi-Fi but cannot access the internet.
- The problem began after changing router settings.
- DNS, LAN, DHCP, mesh, extender, or IP settings were recently modified.
- The router was replaced or reconfigured.
- Internet access fails even though devices remain connected to Wi-Fi.
Do not assume a DNS or DHCP failure merely because the phone says “Connected, no internet.”
Why It May Help
DHCP normally provides devices with the local network information they need to communicate through the router. DNS translates website names into network addresses.
Incorrect manual IP, gateway, DNS, or router configuration can therefore prevent internet access even when the Wi-Fi radio connection itself remains active.
Samsung’s current support documentation shows that Galaxy devices can use DHCP-provided network information or manually configured IP, gateway, and DNS values, confirming that these settings are separate from simply joining Wi-Fi.
Steps
- First confirm whether several devices are affected.
- If only one phone has the problem, leave router DHCP and DNS settings alone for now.
- If several devices are affected, restart the router and modem before editing their settings.
- Think back to any recent router changes involving:
- DNS servers
- DHCP
- LAN addresses
- Static IP assignments
- A new router or mesh system
- If custom values were recently entered, use the router manufacturer’s or ISP’s documentation to return them to the correct automatic or recommended configuration.
- Do not copy random IP addresses, gateway addresses, subnet values, or DNS servers from another person’s network.
- Test internet access again.
- If all devices remain offline, contact the ISP or router manufacturer.
Expected Result
Devices should receive usable network information and reach the internet when the router and ISP connection are configured correctly.
What the Result Means
If correcting a recently changed router setting restores service, that configuration may have caused the failure.
If nothing was changed and the ISP reports an outage, DNS or DHCP changes on your phone are unlikely to solve the outage.
If every other device works normally, a router-wide DHCP or DNS failure becomes less likely, although device-specific network assignment problems can still occur.
Fix 6: Check VPN or Security Software
CONDITIONAL STEP
Use This When
Use this when the problem began after installing or configuring a VPN, security application, filtering service, work profile, or similar network software.
Why It May Help
Network-filtering software can affect how traffic or name resolution passes through the phone even though the phone remains connected to Wi-Fi.
Apple currently includes VPN and security software in its Wi-Fi troubleshooting process.
Steps
- Check whether a VPN is currently connected.
- Temporarily disconnect it if doing so is permitted.
- Test several websites.
- If you use employer-, school-, or organization-managed security software, do not remove the management profile yourself.
- Contact the administrator if disabling or modifying the service is restricted.
- If the problem began immediately after installing a personal VPN or security app, follow that provider’s instructions for disabling or removing it safely.
Expected Result
Internet access may return when a malfunctioning or incorrectly configured network-filtering service is no longer intercepting the connection.
What the Result Means
If turning off the VPN restores access, investigate that VPN’s configuration or provider rather than changing the router.
If nothing changes, reconnect the VPN if required and continue troubleshooting.
Fix 7: Reset Wi-Fi or Network Settings
CONDITIONAL STEP
Use This When
Use this only after:
- Other devices work on the same router.
- Your phone continues having the problem.
- Restarting did not help.
- Forgetting and reconnecting to the Wi-Fi did not help.
- VPN or network-filtering software has been considered.
This is a network reset, not a factory reset.
Before You Reset
Network reset behavior differs by phone.
You may lose saved Wi-Fi networks and passwords and need to reconnect afterward. Depending on the device, Bluetooth pairings, VPN settings, cellular settings, or APN information may also be affected. Apple specifically states that its network reset removes saved Wi-Fi networks and passwords along with cellular, VPN, and APN settings.
Google Pixel
Current Google Pixel guidance lists:
- Open Settings.
- Tap System.
- Tap Reset options.
- Tap Reset Bluetooth & Wi-Fi.
- Tap Reset settings.
- Reconnect to the Wi-Fi network.
- Test the internet.
Samsung Galaxy
On currently supported Samsung guidance:
- Open Settings.
- Tap General management.
- Tap Reset.
- Select Reset Wi-Fi and Bluetooth settings.
- Tap Reset settings.
- Confirm when requested.
- Reconnect to Wi-Fi.
Exact wording varies by Galaxy model and software version.
iPhone or iPad
Apple’s current path is:
- Open Settings.
- Tap General.
- Tap Transfer or Reset [device].
- Tap Reset.
- Tap Reset Network Settings.
- Reconnect to your Wi-Fi network after the device completes the reset.
Expected Result
The phone should create fresh network configurations and reconnect normally.
What the Result Means
- If the phone works afterward, one of its saved network settings may have contributed.
- If the phone still fails only on one Wi-Fi network, return to router or ISP troubleshooting.
- If the phone cannot access the internet through multiple known-working Wi-Fi networks, contact the phone manufacturer before considering any full factory reset.
When to Contact Your Internet Provider
Contact your ISP when:
- Multiple devices connect to Wi-Fi but none can access the internet.
- Restarting the modem and router does not restore service.
- The modem or router shows an abnormal internet or WAN status.
- The problem started without any phone-side changes.
- Your ISP confirms that router settings must be changed.
- Internet access repeatedly disappears for the entire household.
Google, Apple, and Samsung all direct users toward the ISP or network administrator when the Wi-Fi connection exists but the upstream internet service remains unavailable.
Common Mistakes
- Assuming the Wi-Fi icon proves internet access: The icon primarily shows that the phone has connected to the Wi-Fi network. The router’s connection to the wider internet can still fail.
- Changing DNS immediately: DNS problems are possible, but a carrier or ISP outage, disconnected modem, captive portal, router failure, VPN issue, or bad saved network can produce a similar symptom. Diagnose the affected layer before changing DNS.
- Entering random static IP values: An IP address, gateway, subnet, and DNS configuration must match the actual network. Values copied from another router or troubleshooting post can create a second problem.
- Factory-resetting the phone: A full factory reset is not a reasonable early fix for this symptom. If every device on the same Wi-Fi is offline, erasing your phone will not repair the router or ISP connection.
- Factory-resetting the router: Do not confuse restarting a router with restoring it to factory defaults. A factory reset can erase ISP, Wi-Fi, authentication, mesh, and other configuration information.
Frequently Asked Questions
Why does Wi-Fi say connected but there is no internet?
Your phone can successfully connect to a router even when the router cannot reach the internet. Other possibilities include an ISP outage, public Wi-Fi login requirement, saved network problem, VPN or security software, or incorrect router network configuration.
Can DNS cause Wi-Fi to say connected but no internet?
Yes, a broken or incorrectly configured DNS service can prevent normal website-name resolution while the Wi-Fi connection itself remains active. However, the message alone does not prove DNS is responsible. Test other devices and rule out the ISP, router connection, and captive portal before changing DNS settings.
Can DHCP cause connected-but-no-internet problems?
It can. A device needs usable local network information to communicate through the router. Incorrect DHCP or manually configured network information can prevent normal access. If several devices suddenly have the same problem after router configuration changes, router-side DHCP becomes more relevant. If every other device works normally, do not assume the entire router’s DHCP service has failed.
Why does mobile data work while Wi-Fi has no internet?
That usually shows that the phone still has another working path to the internet. It helps narrow the issue toward the Wi-Fi network, router, ISP connection, or the phone’s Wi-Fi-specific configuration rather than a complete loss of internet capability.
Should I factory-reset my phone?
Not as routine troubleshooting for this problem. First isolate the router versus phone, reconnect the Wi-Fi network, check VPN or managed networking, and use the phone’s targeted network reset when justified.

How This Guide Was Verified
Last technically checked:
August 9, 2026
Research method:
Current Google Pixel, Apple, and Samsung support documentation was reviewed. The exact support pages were opened, page titles and procedures were checked, and the clean direct URLs were rechecked before output.
Physically tested:
No documentation reviewed.
Applies to:
Android phones and iPhones that successfully join a Wi-Fi network but cannot access the internet. Exact menus vary by Android manufacturer, software version, router, ISP, network administrator, and region.
Important limitation:
A “connected but no internet” message does not identify one specific cause. Router DNS or DHCP failure is only one possibility. ISP outages, captive portals, VPN software, saved network configuration, and other router or device issues can produce similar symptoms.
Data-loss risk:
Conditional. Forgetting a network removes its saved Wi-Fi credentials. A network-settings reset removes network configuration and may remove Wi-Fi passwords, Bluetooth pairings, VPN, cellular, or APN settings depending on the device. No full factory reset is recommended in this guide.
Final Steps
- Start by testing another device on the same Wi-Fi.
- If several devices are offline, restart the router and modem and check the ISP before changing the phone. If only your phone is affected, forget and reconnect to Wi-Fi, check VPN or network-filtering software, and use a targeted network reset only if the safer steps fail.
- Investigate router DNS or DHCP settings mainly when the problem affects multiple devices or began after network configuration changes. Do not enter random DNS, gateway, or static IP values simply because the phone says it has no internet.
