Overview

Need to add a wired Ethernet port to your desktop? The StarTech.com ST1000SPEX2 is a straightforward PCI Express x1 Gigabit network adapter that delivers a single 10/100/1000 Mbps RJ45 port. Based on a widely supported Realtek chipset, it works with most operating systems without extra driver hassle. The card includes both standard and low-profile brackets, making it suitable for full-size towers as well as compact SFF builds. It's a no-frills solution for restoring network connectivity or adding a second LAN port.

Connectivity & Compatibility

The ST1000SPEX2 connects via a PCI Express x1 slot and is compatible with any motherboard that has an available PCIe slot (x1, x4, x8, or x16). It fully complies with IEEE 802.3, 802.3u, and 802.3ab standards, supporting 10/100/1000 Mbps with auto-negotiation. Auto MDI/MDI-X eliminates the need to worry about cable type — just plug in a standard or crossover Ethernet cable. The card also supports Wake-on-LAN for remote power-on, IEEE 802.1Q VLAN tagging for network segmentation, IEEE 802.1P Layer 2 priority encoding, and IEEE 802.3x full-duplex flow control. Jumbo frames up to 9K are supported, enabling slightly improved throughput in local transfers.
