Ethernet Connected but No Internet? How to Troubleshoot a Wired Connection

Ethernet connected but no internet? Your computer may have a physical connection to the local network without a working path to the internet. Start by testing another website and another device, then check the cable, router port, and your computer’s network settings.

These steps can help you find the cause before replacing equipment or resetting your network. Menu names vary by device and software version.

1. Check whether the problem affects other devices

Try several websites and another browser. Then use a phone on the same home Wi-Fi network. If Wi-Fi devices also cannot reach the internet, the issue may involve your router, modem, or internet provider. Check your provider’s outage page using mobile data. For a broader walkthrough, see Wi-Fi connected but no internet.

If Wi-Fi works but the wired computer does not, focus first on the Ethernet cable, the router’s LAN port, an adapter or dock, and the computer. Turn off Wi-Fi temporarily during wired tests so it does not hide the result. Re-enable it afterward.

2. Check the cable and use a LAN port

Gently reseat both ends of the Ethernet cable: one in the computer or Ethernet adapter and one in a numbered LAN port on the router or gateway. Do not move the cable that connects a separate modem to the router’s WAN or Internet port. If the cable passes through a wall jack, switch, or powerline adapter, include those connections in your checks.

Look for damaged insulation or a broken plug. Try a known-good cable, and then another available LAN port. Change one thing at a time and retest. A link light can indicate a physical connection, but it does not prove the internet works; some equipment has no visible light.

3. Bypass a dock or adapter if possible

If you use a USB Ethernet adapter or docking station, unplug and reconnect it. Try another compatible USB port and, if practical, a direct Ethernet port or another known-good adapter. A dock may need power, a compatible driver, or a firmware update from its manufacturer. On a work-managed computer, consult your IT team before changing drivers or network settings. If you need an adapter, shop USB Ethernet adapters and check compatibility with your computer.

4. Restart the computer and check network status

Restart the affected computer. On Windows, open Settings → Network & internet → Ethernet and review its status. On a Mac, open System Settings → Network and select the Ethernet service. Exact menus vary. If the adapter is disabled, enable it only if this is your personal computer and doing so is appropriate for your network.

Windows users can run the Network and Internet troubleshooter in Get Help. If the connection stopped after an update, consult the computer or adapter maker for the correct driver. Avoid uninstalling a driver until you have a suitable backup and a way to reinstall it.

5. Check IP and DNS settings carefully

Most home networks automatically assign an IP address and DNS servers. If your computer is set to manual values you did not intend, record the existing settings and consult your provider or device instructions before changing them. A self-assigned address beginning with 169.254 can suggest the computer did not receive an address from the network, but it does not identify the cause by itself.

Temporarily disconnect a personal VPN and check for an unintended proxy, then test again. Reconnect your VPN afterward if needed. Do not change settings on a managed computer without permission or permanently disable security software.

6. Restart network equipment if multiple devices are affected

A restart temporarily interrupts everyone using the connection. If you have a separate modem and router, unplug both power supplies, wait about 30 seconds, reconnect the modem first, and allow it to come online. Then reconnect the router and wait several minutes before testing. If you have one combined gateway, restart that one device. Follow your provider’s instructions for battery-backed or special equipment.

A restart is not a factory reset. Avoid the reset button as an early troubleshooting step; a factory reset can erase Wi-Fi credentials and other settings.

7. What your test results suggest

Another cable fixes it: the original cable or connector may be faulty. Another LAN port works: the original port may be faulty or configured differently. Another computer works with the same cable and port: investigate the first computer or its adapter. Neither wired nor Wi-Fi devices work: investigate the router, gateway, or provider. These are clues, not guarantees.

When should you contact support?

Contact your internet provider if multiple devices cannot get online after an outage check, cable inspection, and restart. For a single affected computer, contact the computer or adapter manufacturer. Note which cables, ports, and devices you tested and any exact error message. Follow Microsoft’s Ethernet troubleshooting guide or Apple’s internet connection guidance for model-specific steps.

Frequently asked questions

Why does Ethernet say connected but websites do not load?
The physical connection can be active while the router, internet service, IP configuration, DNS, VPN, or another component prevents access. Test another device and follow the checks above.

Can a bad Ethernet cable cause this?
Yes. A damaged or unreliable cable can prevent or interrupt a connection. A known-good replacement is a useful test, but a cable is not the only possible cause.

Should I reset my router?
Try a normal restart only when appropriate. Reserve a factory reset for later, after understanding what settings it will erase or when your provider directs you.
