This machine was last connected to the internet March 2015. It's got Windows 7. It boots fine, clock is correct. My plan was to connect to the Internet through my AirPort Extreme (it's got a firewall) and immediately update my AV, and Windows. So I plug it up and boot, and it won't connect. It says there is no network hardware. So my question is this: Do you think it's not connecting to the net because Windows is over two years out of date? I'm thinking the Windows firewall is blocking it but when I try to change it I get error messages. Or is it more likely a hardware failure in the ethernet card?
