The REALTEK Wireless LAN Driver is the software driver for the Realtek Wireless LAN NICs. It is a program used to communicate from the Windows PC OS to the device. This software is required in most cases for the hardware device to function properly. In most cases, drivers come with Windows or can be found by going to Windows Update in Control Panel and checking for updates as well as downloaded from the Realtek support website.
