I’ve seen that before, it’s often a power or link negotiation issue.

Open Device Manager, go to your Ethernet adapter, then in Properties uncheck “Allow the computer to turn off this device to save power.” Disable “Energy Efficient Ethernet,” and keep “Speed & Duplex” set to Auto Negotiation.

If it still drops, try another router or switch port.
