Satellite Pro L630-12: Ethernet controller v Network adapter v. WLAN
My Satellite Pro L630-12E has (A) an Atheros AR8151 PCI-E Gigabit Ethernet Controller and (B) Broadcom 802.11n Network Adapter.
Toshiba keeps regularly advising me that an updated Wireless Lan Driver has been released, which I must install.
First question: Is the Wireless LAN Driver the Ethernet Controller or the Network Adapter?
I check the versions on my machine of both (A) and (B) with the PC diagnostics tool and find that (B) is the latest version (220.127.116.11) and (A) is a very old version (18.104.22.168). I download from the Wireless LAN Driver Downloads page the latest version (22.214.171.1246.0) of "Atheros Wireless LAN Adapter" for my machine (Windows 7 (64)) and run the file. But still, wherever I look, my machine continues to state that the version of (A) is (126.96.36.199).
Second question: Am I updating the Atheros Ethernet Controller when I download and run the Atheros Wireless LAN Adapter?
If yes, then why doesn't it show the most recent version information?
Sorry for basic questions, but I haven't found explanations in various fora about the difference between 'ethernet controller', 'network adapter' and 'wireless LAN' after searching many times. I am concerned that Toshiba keeps informing me that I don't have the most recent version of the wireless LAN driver despite my efforts to follow their instructions.
