When Intel Ethernet Keeps Disconnecting

Intermittent drops often come from power management. In the adapter properties, disable options that let Windows turn off the device to save power. Try a different cable and port on the router.

Update the driver, then test. If you recently changed Windows versions, a clean driver reinstall helps. Check the BIOS for any network-related settings too.

Use the event viewer to look for network errors with timestamps. They can show whether disconnects line up with sleep, updates or something else. Patience and a methodical approach usually win.
