About this tag
The autonegotiate tag covers discussions about network interface card (NIC) speed and duplex settings in Windows, particularly when autonegotiation fails. A common issue is Windows reporting 'Network cable unplugged' when the NIC is set to autonegotiate, even though the cable and router support gigabit speeds.

The tag focuses on troubleshooting autonegotiation problems with Realtek and other gigabit Ethernet adapters, often involving router or driver settings.
