We recently had some storms in the area and now I cannot access the internet through the 82574L ethernet card in our mid-2010 Mac Pro.
With the ethernet connected, I can log into the router, but I do not get any internet. The cables and router are good as I connected everything to a laptop to test the line. It is only the Mac Pro that will not connect to the internet. The machine will connect to the internet via wifi.
Is it possibly a software (driver) issue that I can somehow reset or reinstall?
Thank you for any advice.
The Mac Pro is running Mac OS X 10.9.5 (Mavericks).
