First question: Is the Wireless LAN Driver the Ethernet Controller or the Network Adapter?
Ethernet controller can be both; WLan and LAN… in your case I assume WLan is Ethernet controller… this would appear if the WLan driver is not installed
Your notebook L630-12E seems to support Broadcom BCM94313 WLan card and the driver can be found here:

Am I updating the Atheros Ethernet Controller when I download and run the Atheros Wireless LAN Adapter?
This is LAN driver!
