| Router DHCP table full or router needs reboot | Restart the router |
| MAC address filtering on the router blocking the PC | Check router MAC filtering |
How to Fix Windows Error ethernet-no-internet — Step by Step
Try a different Ethernet cable
Swap the cable connecting your PC to the router or wall port. Ethernet cables develop faults from bending and wear. A new Cat5e or Cat6 cable costs under $10.
Reset IP configuration
CMD as Admin:ipconfig /releaseipconfig /flushdnsipconfig /renew
Then check: ipconfig /all
You should see a valid IP (like 192.168.x.x) and a Default Gateway matching your router.
Change DNS servers
Control Panel > Network and Sharing Center > Change adapter settings > right-click Ethernet > Properties > IPv4 > Use the following DNS:
Preferred: 8.8.8.8
Alternate: 8.8.4.4
Restart the router
Power cycle your router completely: unplug for 30 seconds, plug back in, wait 2 minutes. A full restart clears the DHCP table and resets routing tables.
Check router MAC filtering
Log into your router admin panel (usually 192.168.1.1 or 192.168.0.1) > look for MAC Filtering or Access Control > ensure your PC's MAC address is not blocked. Find your MAC: CMD > ipconfig /all > Physical Address.

Frequently Asked Questions
Why does Ethernet show connected but no internet?
The cable and adapter are working (connection established) but the route to the internet is broken. Causes include wrong IP, DNS failure, or the router not forwarding traffic.
How do I know if the cable is faulty?
Try the cable on another device. If that device also has issues, the cable is bad. A network cable tester ($15) can identify breaks precisely.
Is this my ISP's fault?
Check by connecting a different device via Ethernet to the same port. If that device has internet, the problem is your PC's settings. If not, contact your ISP.
What does a 169.254.x.x IP mean?
Your PC could not get an IP from the router (DHCP failed) and assigned itself an automatic private IP. This never works for internet. Power cycle the router and run ipconfig /renew.
Should Ethernet be faster than WiFi?
Yes. Ethernet provides more stable and usually faster speeds with no interference. If your Ethernet is slower than WiFi, check cable quality and whether the port supports Gigabit.
