The Intel PRO/1000 GT PWLA8391GT PCI Gigabit Network Card with Bracket is a network adapter designed for wired-Ethernet connectivity. This card, with a single Ethernet port, is manufactured by Intel and provides high-speed network access for computers and networking interfaces. Designed for installation in a PCI slot on a motherboard, this card does not work in modern PCIe slots.I have not been able to test this card due to not having a PCI slot to test with. It may very well work just as it did last time I used it.
