Ethernet issues, WiFi is fine. Need assistance.
Suddenly, the Ethernet connection vanished. I unplugged it and swapped in a different PCIe card, but nothing worked. It’s not the cable itself. The port is showing green. I’ve adjusted the speed to 1GB, toggled it on and off, reinstalled drivers manually, performed a network reset, and even reset the TCP stack—still nothing! The Wi-Fi is functioning. Please help me resolve this urgently. I’m really stressed.

Try disabling Windows Filtering Platform and test again. If that doesn't help, change your cables or switch to a different port on the router. Do you see any activity lights now?

Try pinging the gateway using a command like "ping 192.168.1.254" (replace with your actual gateway). Confirm the gateway responds. Ensure your assigned IP is valid and not set to APIPA.

The advice from another operating system is helpful. You can start Ubuntu (or similar) from a USB drive without installing it directly. If it functions on another OS...reinstall. Please share a screenshot of Wireshark.
