Quick answer

Reboot in the right order first: modem, then router. That one fix clears most of these faults. If it does not, test a second device. When every device is offline, the problem is the router, the modem or your provider, not the device in your hand. Then work down the layers in the diagram below, and stop when one of them answers.

Your Wi-Fi says connected, but nothing will load. This is the most common fault in a home network, and it is almost always one of five things. Your provider may be down. The modem or router may have stalled. Your DNS may be wrong. A VPN or proxy may be in the way. Or the device itself may hold a bad address.

Key Takeaways

  • 💡​Reboot the modem first, then the router. That order clears most of these faults.
  • 🌐​An address starting with 169.254 means the router never answered – no DNS change will help.
  • 📞​Every device offline at once points at the router, the modem or your provider, not the device in your hand.
  • 🏭​Factory reset is the last resort. It erases your Wi-Fi name and password.

Reasons for “WiFi Connected But No Internet Connection” Problems

Five things sit between your keyboard and the internet. The fault is in one of them.

Five layers between your device and the internet, what each one looks like when it is the fault, and the first check for each. Where the fault is, layer by layer Work from the top down. Stop as soon as one layer answers. 1 Your device Only this one device is offline. First check Load a page on a second device. 2 The Wi-Fi link Connected, but nothing loads. First check Does the same fault appear over Ethernet? 3 The router Every device in the house is offline. First check Reboot the modem first, then the router. 4 The modem The router never gets a public address. First check Read the modem lights, then its event log. 5 Your provider Modem and router both look healthy. First check The provider’s own status page. One device only? Start at layer 1. Every device in the house? Go straight to layer 3.
The five layers between your device and the internet. Commands and Windows steps from Microsoft’s own documentation, listed below and re-checked on 2 October 2026.
The five words this page uses
DNS
The service that turns a name like example.com into the number a computer needs. If DNS fails, the Wi-Fi still shows connected but no page will open.
DHCP
How your router hands out IP addresses. If this breaks, a device can join the Wi-Fi and still have no usable address.
IP address
The number your device uses on your own network. A 169.254 address starting with those digits means the device asked for one and got no answer.
MAC address filtering
A router rule that allows or blocks named devices by their hardware address. It can lock out one device while every other device works.
Factory reset
Wipes the router back to its shipped state. Every setting you chose is gone, including the Wi-Fi name and password.

Before we start with the solutions, let’s understand some common reasons that might cause this issue:

  1. Internet provider outage in your area.
  2. Modem or router problems.
  3. Incorrect network permissions.
  4. Network settings conflict.
  5. Incorrect DNS server settings.
  6. Proxy, VPN, or security software interference.
  7. Malware or viruses.

Troubleshooting Steps for “WiFi Connected But No Internet Connection”

Nine steps, cheapest first. Stop as soon as the internet returns.

Step 1: Isolate the problem and, if required, Reboot Your Affected Devices

Before moving to more complex troubleshooting methods, try these simple steps:

  • Isolate the problem: Try a second device on the same Wi-Fi. Load a page on your phone, a tablet or another computer. If that device works, the fault is in the first device, not the network.
  • Reboot Your Affected PC: This can resolve temporary glitches and fix network connection issues.
  • Reboot the modem and the router. Unplug both from the wall. Wait a minute. Plug the modem back in first and let it finish starting up. Then plug the router back in. Give both a few minutes before you test again.

Step 2: Check Your ISP’s Status

There could be an internet provider outage in your area. To confirm, you can:

  • Visit the customer-facing website or social media pages of your internet service provider for any outage notifications.
  • Use external resources like Down Detector or the Thousand Eyes Outages Map to check for aggregated outage data.
  • Reach out to your provider’s customer support if no outage information is found.
Windows VPN Connection

Step 3: Disable Proxy, VPN, and Security Software

Both Proxy, VPNs, and some security software can interfere with network connections. Therefore:

  • Temporarily disable any active Proxy, VPN connections, and third-party antivirus applications.
  • After disabling, check if your connection is restored.
Windows Network Troubleshooter

Step 4: Run the Windows Network Troubleshooter

Tip

Write down the address your device gets before you change anything. Run ipconfig and note the IPv4 address and the default gateway. If the address starts with 169.254, your router never answered, and no DNS change will help.

Windows has a built-in network troubleshooter that can on its own detect and fix common network connection problems.

To run it on Windows 10:

  • Go to Settings > Network & Internet > Status.
  • Click on “Network troubleshooter” and follow the prompts provided.

On Windows 11:

  • Settings > System > Troubleshoot.
  • Other troubleshooters > Internet Connections and follow the prompts.
Windows Advanced IP and DNS Settings

Step 5: Review IP Settings

Make sure that your IP settings are configured correctly:

  • Windows 10: open Settings, then go to Network & Internet > Status > Change adapter options. Double-click the connection you are using and open Internet Protocol Version 4. Make sure both “Obtain an IP address on its own” and “Obtain DNS server address on its own” are selected.
  • Windows 11: open Settings and go to Network & Internet > Advanced network settings, then select your connection. Choose “View extra properties” and check that both “Obtain an IP address on its own” and “Obtain DNS server address on its own” are selected.

Step 6: Access your Home Router and Verify Router Permissions

Check the router for MAC address filtering. That feature can block one named device on purpose. Make sure no rule is denying the device you are testing with.

The router’s admin page is where you change the Wi-Fi name, the password and other network settings. The exact steps differ by model. The shape of the page is much the same on most routers.

Follow these steps:

  1. Connect to your network: You must be connected to your router’s network to access its admin page. You can connect either through Wi-Fi or using an Ethernet cable.
  2. Find your router’s IP address: This is typically a string of numbers separated by periods (e.g., 192.168.1.1). The exact IP address can vary based on your router model and network setup.
    • In Windows, you can usually find this by opening Command Prompt and typing ipconfig, then read the line marked Default Gateway.
    • On Mac, you can go to System Preferences > Network > Advanced > TCP/IP and look for “Router”.
    Both are the same address, and it is usually 192.168.1.1 or 192.168.0.1.
  3. Enter the IP address into your web browser: Open a web browser on your device and type in the router’s IP address into the address bar, then hit Enter.
  4. Log in: You’ll be prompted for a username and password. If you never changed them, the default login is in the router’s manual or on the sticker on the box. A web search with the model name also works.
  5. Navigate the console: Once logged in, you can change various settings related to your network. Be careful, as making incorrect changes can cause your network to stop working. It’s a good idea to document any changes you make so you can revert them if necessary.

Remember, every router is different. While these general steps will apply to many routers, yours might be a little different. If in doubt, consult your router’s user manual or the maker’s website.

Step 7: Reset Network Settings

Resets the Winsock catalog to a clean state, removing any custom LSPs to resolve network problems caused by corrupted Winsock settings.

Microsoft, netsh winsock command reference (Microsoft Learn)

That is the whole point of the reset. It clears a damaged layer between Windows and the network, which is why it fixes faults that survive a reboot.

If you’re still facing connection issues, resetting your network settings can help. Execute the following commands one by one in the Command Prompt (run as administrator) on your Windows-based computer:

  1. netsh winsock reset: This command resets the Winsock catalog back to the default (or clean) state. Windows should confirm the reset and ask you to restart.
  2. ipconfig /release: This command releases the current IP setup. You’ll see that all the IP-related information (like IP address, subnet mask, etc.) becomes blank.
  3. netsh int ip reset: This command resets IP settings. If you’re using IPv4, you’ll see a series of reset messages. If you’re using IPv6, you’ll see a message saying that the reset command is available only for IPv4.
  4. ipconfig /renew: This command renews the DHCP setup. The PC asks the router for a fresh IP address. The new address is printed in the window.
  5. ipconfig /flushdns: This command flushes and resets the contents of the DNS client resolver cache. After running this command, you’ll see a message that the DNS resolver cache was successfully flushed.

After executing these commands, reboot your PC and check if your internet connection is restored.

Step 8: Factory Reset Router and Modem

It came back, then failed again?

An intermittent fault is usually one of three things. The modem is losing sync on the line, which the modem log will show as repeated range or sync events. The router is overheating or its power supply is failing. Or a second device on your network is using all the bandwidth. Check the modem log first, because it survives a reboot and the others do not.

If every device in the house is offline, a factory reset is the last resort.

This can be done either physically using the reset button on the devices or via the device interface.

Step 9: Contact Your ISP

If you’ve tried everything and still don’t have internet access, your ISP might be experiencing problems. Give them a call.

Preventative Measures to Avoid “Wifi Connected But No Internet Issue”

It’s better to prevent an issue than fix it. Here are some preventative measures:

A. Keep the Firmware/Software on Your Router Up-to-Date

If the router is the fault A router that no longer gets updates is a router to replace

This page asks you to keep the router firmware current. When the maker has stopped shipping updates for your model, that advice cannot be followed, and a router that keeps dropping the connection is usually the end of its life. Both routers below are Wi-Fi 6 with Gigabit ports and current firmware.

Routers often receive updates that improve security and performance. Check regularly for updates and apply them. You can log in to your home router (steps mentioned above) and check if it is showing any update.

B. Secure Your Network with a Unique and Complex WiFi Password

A unique and complex WiFi password prevents unauthorized access that might interfere with your network.

C. Avoid Interference with Other Devices

Certain devices like cordless phones or microwaves can interfere with your wifi signal. Try to keep your router away from these devices.

D. Use a Wired Connection (Ethernet)

A wired connection can provide a more stable and faster connection than a wireless one.

What Are the Possible Causes of Ethernet Connection But No Internet Access?

When troubleshooting ethernet connected but no internet access issues, there can be several potential causes. It could be due to a faulty Ethernet cable, outdated network drivers, incorrect DNS settings, or a problematic network adapter. Inspecting these factors thoroughly and making necessary adjustments can help resolve the issue and restore internet connection.

Conclusion

If none of the steps above worked, call your provider. Ask them to test the line to your address. Deeper faults need their tools, not yours.

By following this guide systematically, you’re likely to fix the “connected but no internet” issue. Regular proactive measures to maintain your network’s health can prevent such problems from arising in the future.

Bottom line. Reboot the modem first, then the router, and give both a few minutes. Test a second device to find out whether the fault is the device or the network. Work down the five layers and stop when one of them answers. Save the reset commands for the faults that survive a reboot, and treat a factory reset as the last resort.
