Seeing “Ethernet connected” but no internet access on Windows can be confusing. Your computer may show that the Ethernet cable is connected, yet websites refuse to load, applications cannot connect, or Windows displays “No Internet” or “Connected, no internet”.
The good news is that an Ethernet connection problem does not necessarily mean your network hardware is broken. The cause can range from a temporary router problem and incorrect IP configuration to DNS errors, outdated network drivers, or corrupted Windows network settings.
This guide explains why Ethernet can be connected without internet access and provides practical solutions for Windows 11 and Windows 10.
Why Is Ethernet Connected but There Is No Internet?
When Windows says Ethernet is connected, it generally means your computer has established a physical or local network connection with the router or network device. However, that does not guarantee that the router itself has a working connection to the internet.
Common causes include:
- Router or modem problems
- Incorrect IP address configuration
- DNS server problems
- DHCP errors
- Corrupted TCP/IP settings
- Faulty Ethernet cables or ports
- Outdated or damaged network drivers
- VPN or proxy interference
- Windows Firewall or security software conflicts
- Temporary problems with your internet service provider
Before making major changes to Windows, start with the simplest troubleshooting steps.
1. Check the Ethernet Cable
A damaged or poorly connected Ethernet cable can cause unstable connectivity.
Disconnect the Ethernet cable from your computer and router, then reconnect it firmly. Check whether the Ethernet port has a link/activity light.
If possible, test with another Ethernet cable. You should also try another LAN port on your router.
A cable may look perfectly normal while having an internal fault, so testing with a known-working cable is often faster than trying to diagnose the cable itself.
2. Restart Your Router and Computer
A simple restart can resolve temporary networking problems.
First, shut down your Windows computer. Then unplug your router and modem from power.
Wait approximately 30–60 seconds before reconnecting them. Give the network equipment several minutes to fully start.
After the router’s indicator lights return to normal, turn on your computer and test the internet connection.
If other devices connected to the same router also cannot access the internet, the problem is probably related to the router, modem, or ISP rather than your Windows PC.
3. Check Whether Other Devices Have Internet Access
This is one of the quickest ways to identify where the problem is.
Connect a smartphone, laptop, or another computer to the same network.
If other devices can browse normally but your Windows computer cannot, focus on Windows and its network configuration.
If every device is connected to the router but has no internet, check the modem/router connection and contact your internet provider if necessary.
4. Run the Windows Network Troubleshooter
Windows includes built-in troubleshooting tools that can automatically detect some common network problems.
On Windows 11:
- Open Settings.
- Select System.
- Choose Troubleshoot.
- Select Other troubleshooters.
- Run the Network and Internet troubleshooter if available.
On Windows 10, open Settings > Update & Security > Troubleshoot and look for the available network troubleshooting options.
The troubleshooter may identify problems involving network adapters, configuration, or connectivity.
However, automated troubleshooting does not fix every Ethernet problem. If the issue remains, continue with the following methods.
5. Check Your IP Address
An incorrect IP configuration can prevent Windows from communicating properly with your router or accessing the internet.
Open Command Prompt as an administrator and run:
ipconfig
Look for the Ethernet adapter.
A normal local network configuration generally includes an IPv4 address, subnet mask, and default gateway.
If Windows shows an address beginning with 169.254, the computer may not have received a valid IP address from the router’s DHCP server.
You can try renewing the IP configuration with:
ipconfig /release
ipconfig /renew
Then test your connection again.
6. Reset DNS Settings
DNS translates website names such as example.com into IP addresses. If DNS is malfunctioning, your Ethernet connection can appear active while websites fail to load.
First, clear the Windows DNS cache.
Open an elevated Command Prompt and run:
ipconfig /flushdns
You should see a message indicating that the DNS resolver cache was successfully cleared.
You can also test whether DNS is the problem by temporarily using a reliable public DNS service. For example, commonly used public DNS addresses include:
- Google DNS:
8.8.8.8and8.8.4.4 - Cloudflare DNS:
1.1.1.1and1.0.0.1
If changing DNS restores access, your original DNS configuration may have been the source of the problem.
7. Reset TCP/IP and Winsock
Windows networking depends on components such as TCP/IP and Winsock. If these components become corrupted or misconfigured, internet access may stop working even though Ethernet remains connected.
Open Command Prompt as Administrator and execute:
netsh winsock reset
netsh int ip reset
Restart Windows after running these commands.
You can then test the connection again.
This method is particularly useful when the problem appeared after installing software, changing network settings, using a VPN, or recovering from a previous networking problem.
8. Disable and Re-enable the Ethernet Adapter
Sometimes the network adapter simply needs to be restarted.
Press Windows + R, enter:
ncpa.cpl
and press Enter.
Find your Ethernet connection, right-click it, and select Disable.
Wait several seconds, then right-click it again and choose Enable.
Windows will restart the network adapter and attempt to establish the connection again.
This is a quick solution worth trying before changing advanced network settings.
9. Update or Reinstall the Ethernet Driver
A faulty, outdated, or incompatible network driver can cause connectivity problems.
To check your Ethernet driver:
- Right-click the Start button.
- Open Device Manager.
- Expand Network adapters.
- Locate your Ethernet adapter.
- Right-click it and select Update driver.
If updating does not solve the problem, you can uninstall the network adapter and restart Windows. Windows may automatically reinstall the driver.
For the most reliable driver, you can also visit the motherboard or computer manufacturer’s official support website and download the driver designed for your exact model.
Avoid downloading network drivers from unknown third-party websites.
10. Temporarily Disable VPN and Proxy Settings
VPN applications and proxy configurations can interfere with normal internet traffic.
If you recently installed or enabled a VPN, disconnect it and test your connection.
You can also check Windows proxy settings under the network and internet settings.
If internet access returns after disabling the VPN or proxy, the problem may be related to its configuration rather than your Ethernet hardware.
Remember to restore your preferred security and privacy settings after testing.
11. Perform a Windows Network Reset
If several network troubleshooting methods have failed, Windows provides a Network reset feature.
On Windows 11, open:
Settings > Network & internet > Advanced network settings > Network reset
On Windows 10, the option can be found under:
Settings > Network & Internet > Status > Network reset
Network reset removes and reinstalls network adapters and returns certain network settings to their defaults.
Because this can affect saved network configurations and VPN-related software, use it after trying less disruptive solutions.
Restart the computer after performing the reset.
12. Check the Router and ISP Connection
If Windows appears to be configured correctly but there is still no internet, the problem may not be on your computer.
Log in to your router’s administration interface if necessary and check its internet/WAN status.
Look for signs such as:
- WAN disconnected
- No IP address from the ISP
- Internet service unavailable
- Modem connection errors
- Red or abnormal status lights
You can also check whether your internet provider is experiencing an outage.
If multiple devices connected to the same router cannot access the internet, contacting your ISP may be the most appropriate next step.
How to Identify the Source of the Problem
You can narrow down the problem by testing different parts of the connection.
Think of the connection as:
PC → Ethernet cable → Router → ISP → Internet
If the Ethernet connection itself is not detected, investigate the cable, Ethernet port, or network adapter.
If the PC communicates with the router but cannot reach the internet, investigate IP configuration, DNS, router settings, or the ISP.
If other devices also have no internet, the Windows PC is less likely to be the root cause.
Useful Command Prompt Tests
Windows includes several commands that can help identify network problems.
Test the Local Network
Run:
ping 192.168.1.1
The exact router address may differ.
If you receive replies, your PC may be communicating with the router.
Test Internet Connectivity
Try:
ping 8.8.8.8
If this works but websites do not open, DNS could be the problem.
Test DNS Resolution
Run:
ping google.com
If pinging an IP address works but the domain name does not resolve, investigate your DNS configuration.
Ethernet Connected but Showing “No Internet” After a Windows Update
Sometimes network problems appear immediately after Windows updates.
If the issue started after an update, first restart the computer and router. Then check for a newer network driver from your PC or motherboard manufacturer.
You can also inspect recent Windows updates if you strongly suspect that an update caused the problem.
Avoid removing security updates without a clear reason. A driver or configuration issue is often a safer explanation to investigate first.
What If Ethernet Works but Wi-Fi Does Not?
If Ethernet provides internet access while Wi-Fi does not, the issue is probably related to the wireless adapter, Wi-Fi driver, wireless configuration, or router’s Wi-Fi settings.
The opposite is also useful diagnostically.
If Wi-Fi works but Ethernet does not, concentrate on:
- Ethernet cable
- Router LAN port
- Ethernet adapter
- Ethernet driver
- TCP/IP configuration
- Ethernet adapter settings
This comparison can save considerable troubleshooting time.
When Should You Replace the Ethernet Cable?
Consider replacing the cable if:
- The connection repeatedly disconnects
- Windows switches between connected and disconnected states
- The Ethernet link speed is unexpectedly low
- The cable has visible physical damage
- Another cable works correctly
- Moving the cable causes the connection to drop
A replacement Ethernet cable is inexpensive compared with replacing networking hardware, so testing with another cable is often worthwhile.
Frequently Asked Questions
Why does Windows say Ethernet is connected but there is no internet?
“Ethernet connected” usually indicates that Windows detects a physical or local network connection. Internet access can still fail because of router problems, incorrect IP settings, DNS issues, network drivers, or an ISP outage.
Can DNS cause Ethernet to show no internet?
Yes. DNS problems can prevent Windows from resolving website addresses even when the underlying network connection is working.
Will restarting the router fix Ethernet problems?
It can. Restarting the router clears temporary network states and forces it to establish a new connection with your ISP and connected devices.
Does a 169.254 IP address mean there is a problem?
Usually, yes. A 169.254.x.x address is typically automatically assigned by Windows when it cannot obtain a valid IP address from a DHCP server.
Should I reset Windows to fix Ethernet?
Usually not. A complete Windows reset is excessive for most Ethernet problems. Try network resets, driver troubleshooting, DNS checks, and router diagnostics first.
Final Thoughts
An Ethernet connection with no internet access on Windows does not automatically mean your computer’s Ethernet port is defective. In many cases, the problem can be traced to a temporary router issue, incorrect IP configuration, DNS failure, corrupted Winsock settings, or a network driver problem.
Start with the simplest solutions: check the cable, restart the router, test another device, and restart the Ethernet adapter. If those steps fail, move on to IP renewal, DNS troubleshooting, TCP/IP and Winsock resets, driver updates, and Windows Network Reset.
The most important diagnostic clue is whether other devices can access the internet through the same router. That single test can quickly tell you whether to focus on your Windows PC or your network/ISP.
With a systematic approach, most Ethernet connected but no internet problems can be identified and resolved without reinstalling Windows or replacing your computer.
