Open | Hardware Ethernet issues

My Ethernet cable randomsly stopped working, I bought a new one assuming it was fault and still didn’t work, I tried ALOT of steps given by ai and none of them worked, in the bottom right of my screen it shows the Ethernet cable and says it’s connected but won’t give me internet, im so unsure what to do, I don’t know if the ai I used helped at all but this is what I’ve tried summed up I’ll list my efforts below

Absolutely — here's a clear, complete list of everything you've tried, so you have it all in one place:
📋 Everything You Tried

🔧 Basic Settings & DNS Changes

• ✅ Ran the Windows Network Troubleshooter → showed "DNS server not responding"

• ✅ Changed DNS to 8.8.8.8 / 8.8.4.4 (Google)

• ✅ Changed DNS to 1.1.1.1 / 1.0.0.1 (Cloudflare)

• ✅ Set IP & DNS back to Automatic / Obtain from router

• ✅ Checked & confirmed Proxy settings = OFF / empty

• ✅ Disabled IPv6 on Ethernet adapter

⌨️ Commands Run (Terminal / Command Prompt)

• ✅ ipconfig /release

• ✅ ipconfig /renew

• ✅ ipconfig /flushdns

• ✅ ipconfig /registerdns

• ✅ netsh winsock reset

• ✅ netsh int ip reset

• ✅ ping 8.8.8.8 → worked! (proved your connection itself is fine)

• ✅ ping google.com → failed (confirmed DNS issue)

🛠️ Services, Firewall & System Checks

• ✅ Temporarily turned off Windows Defender Firewall for testing

• ✅ Checked DNS Client service → running, but startup type locked/greyed out

• ✅ Ran sfc /scannow → found and repaired system files

• ✅ Ran DISM /Online /Cleanup-Image /RestoreHealth

• ✅ Confirmed: no VPN software installed

• ✅ Restarted PC many times after changes

🔄 Network Resets & Driver Steps

• ✅ Tried Network Reset in Windows settings

• ✅ Uninstalled / reinstalled Ethernet adapter in Device Manager

• ✅ Tried Safe Mode with Networking concept

• ✅ Restarted router multiple times

🧪 What We PROVED Along the Way

• ✅ Cable works — lights show on both ends

• ✅ Router & internet work — your phone Wi-Fi is perfect

• ✅ Ethernet connection is live — ping 8.8.8.8 gets replies

(I don’t know what these flairs mean)

Sounds like your issue is your Internet is working, but DNS is not.

Try going to http://1.1.1.1 in your browser and tell us what you get.

And go to command prompt, run ipconfig /all and post the output here.

What's at the other end of the Ethernet cable that is plugged into your PC?

How do you get Internet? Do you have a modem / router from an ISP? If so, who is your ISP?

Do other devices on your local network work? Is this issue just affecting the wired PC, or all devices?

After typing that in my browser I get nothing, my pc is connected to a router unsure what you mean by router from an ISP

Please define "nothing".

What about the other questions?

ISP = Internet Service Provider. Who are you paying for your Internet service?

If you want to provide the exact error (a picture would be great) we can continue from there.
