Q: What chipset does this network card use? Is it reliable?
A: It uses the Realtek RTL8111 chipset, one of the most widely deployed Gigabit Ethernet controllers in the industry. It is known for stable, low-latency performance and excellent driver support across operating systems.
Q: How many network ports does this card provide?
A: It provides 2 independent RJ45 Gigabit Ethernet ports, allowing you to add two separate 1Gbps LAN connections through a single PCIe slot.
Q: What PCIe slot does this card require?
A: It fits into a PCIe x1 slot or any larger PCIe slot (x4, x8, x16). A low-profile bracket is included, making it compatible with both standard ATX and small form factor (SFF) cases.
Q: What speeds does it support?
A: It supports 10/100/1000 Mbps (auto-negotiation), automatically matching the speed of your router, switch, or network infrastructure.
Q: Which operating systems are compatible?
A: It supports Windows 10, Windows 11, Windows Server editions, and Linux. It is plug-and-play on most modern systems without manual driver installation.
Q: Do I need to install drivers manually?
A: On Windows 10/11 and most Linux distributions, the card is recognized automatically. If your system does not detect it, you can download the RTL8111 driver from the link provided on this page.
Q: Can I use both ports simultaneously?
A: Yes. Both ports operate independently and can be used at the same time — for example, connecting to two different networks, setting up link aggregation (if your switch supports it), or using one port for WAN and one for LAN.
Q: Is this card compatible with servers and workstations?
A: Yes. It is compatible with desktop PCs, workstations, and servers that have an available PCIe slot. It is commonly used in NAS builds, home labs, and small business servers.
Q: Does it support Wake-on-LAN (WoL)?
A: Yes, the RTL8111 chipset supports Wake-on-LAN, allowing you to remotely power on your system over the network when the feature is enabled in your BIOS/UEFI settings.
Q: What is included in the package?
A: The package includes the PCIe network card, a low-profile bracket for SFF cases, and a user manual. Drivers can be downloaded from the link on this product page.
