The Intel(R) Ethernet Connection (18) I219-LM is a network adapter (Ethernet controller) commonly found in Intel-based laptops and desktops, especially business-class systems. It supports wired Ethernet connectivity and is used to connect your computer to a network via an Ethernet cable.

The driver for this adapter is a software package that enables the operating system (like Windows) to communicate with and manage the Ethernet hardware. Without the correct driver, your computer may not be able to connect to the network, or the connection may be unreliable.
