The SIIG LB-GE0711-S1 is a PCIe x4 network card that adds two RJ45 Ethernet ports running at 2.5G, 1G, 100M or 10M. It uses the Realtek RTL8125 chipset, the same controller found in most 2.5G add-in cards and many desktop motherboards, so driver support is broad. It fits standard and low-profile cases with the included bracket and supports VLAN tagging, jumbo frames up to 16K and Wake-On-LAN. It suits NAS builders, home-lab servers and desktops that need a second fast port or a link to a 2.5G switch; it is not a 10G card, so buyers wanting 10GBase-T should look elsewhere.

Owner feedback on this class of Realtek-based 2.5G card is generally positive: it works once the right driver is installed and delivers the expected 2.5G throughput. Complaints center on driver setup on Linux and on cards running warm in tight cases.
The SIIG LB-GE0711-S1 is a dual-port multi-gigabit Ethernet card for servers and desktop computers. It installs in an available x4 PCIe slot and adds two RJ45 ports. Each port supports 2.5G, 1G, 100Mbps and 10Mbps connections.
The card complies with PCI Express Specification Revision 2.1 and is compatible with the NBASE-T Alliance PHY Specification. It supports IEEE 802.3, 802.3u, 802.3a, 802.3bz (2.5GBase-T), 802.1Q VLAN tagging and 802.3az (Energy Efficient Ethernet). It also supports full duplex flow control (IEEE 802.3x) and jumbo frames up to 16K bytes.
The card supports Wake-On-LAN and RealWoW! remote wake-up. A spare low profile bracket is included, so it fits both standard and low profile chassis.
