I just recently got my office in a (mostly) usable state at the new house, and threw my hand usb installer into the PC I was going to use as a server with a fresh 3tb sata drive, I came back to it today and found things were a hot steaming mess, the scripts I have on my auto installer relies heavily on having an internet connection, this was actually the first time I have had a problem with this, I should make everything fail gracefully, it doesn't, it turns it into a hot mess.
Right away I found the problem, the integrated NIC is putting on a good show, but its all for show.
It gets a link light, you can detect the interface, but it wont DHCP, and wont respond to static settings, I booted a LiveUSB to confirm it wasnt just an issue with this install, no dice.
Maybe now I remember why this PC landed in the reuse pile.....
I know somewhere in this house exists a PCI-E NIC, I just saw it...... a few weeks ago?
