If you're looking to buy a wired PCI network card - we carry several models. These are wired adapters so you'll be plugging a cable into them (like a Cat5/Cat6 cable). The big differentiator with wired networking products is the speeds that they can support. With most network cards it's either gigabit capable or not - with gigabit being another word for a network card that supports 1000mbps. Usually if a card isn't gigabit the maximum speed it will support is 10/100Mbps.
