Simply Fast Network Connection
Whether you need to add an additional Ethernet port to your Mac, or step up to Gigabit Ethernet connectivity for your PC, get a Sonnet Presto™ Gigabit PCIe Basic Gigabit Ethernet adapter card for PCI Express for a simple networking solution! Presto Gigabit PCIe Basic is compatible in Mac Pro⁽¹⁾, and Power Mac G5 & PCs with a PCI Express (PCIe) slot, and its plug-and-play simplicity makes installation a breeze; you'll complete the process in a few simple steps.

Presto Gigabit PCIe Basic offers basic networking connectivity and supports gigabit speeds over common CAT-5 cabling, so costly cable replacement is unnecessary. If your computer already has onboard Gigabit Ethernet, you can add a Presto Gigabit PCIe Basic and use it for dedicated connection to a printer, AirPort® Extreme base station, DSL or cable modem, or a metadata server, while leaving your onboard Gigabit Ethernet port(s) available for other connections. This Sonnet card offers simple configuration, and its 1000/100/10BaseT auto-negotiation and full/half duplex communication support allow it to be used in most networks. Presto Gigabit PCIe Basic also includes a low profile mounting bracket that enables the card to be easily installed in low profile PCs.
