You need to double click the "Broadcom" entry (which is your LAN adapter). The Driver tab should be available then.I can't see the word 'driver tab' on the screenshot.
And here's the one of 'change adapter settings'
I believe this driver should work:Yes driver is very old. From what I recall, the technician did try updating essential softwares when it wouldn't connect but wasn't successful. This was a year ago.
From what I understand, Lan card is a piece of hardware, right? Is there anything that can indicate whether or not the hardware itself is in a functional condition?
Really sorry for the dumb query.
