❓ Frequently Asked Questions
Q: Is this network card compatible with my motherboard?
A: This card uses M.2 B+M Key interface and is compatible with most modern motherboards that have an available M.2 slot. Please check your motherboard specifications to ensure it has an M.2 slot that supports B+M Key cards.
Q: Do I need to install drivers?
A: Yes, for optimal performance, we recommend downloading and installing the RTL8111 driver from the download link provided above.
Q: Can all 4 ports work simultaneously at 1000Mbps?
A: Yes! All 4 RJ45 ports support full Gigabit speed (1000Mbps) and can operate simultaneously. Each port has its own RTL8111H chipset, ensuring independent full-speed operation without bandwidth sharing.
Q: What is the difference between the mainboard and daughter board?
A: The mainboard is the M.2 controller card that plugs into your motherboard's M.2 slot. The daughter board is the RJ45 connector card that holds the 4 Ethernet ports. They connect via the included cables, allowing flexible placement of the ports (e.g., through a PCIe bracket slot).
Q: Is this suitable for NAS or server applications?
A: Absolutely! This card is perfect for NAS systems, home servers, and network equipment. It supports VLAN tagging, jumbo frames (up to 9K), and energy-efficient operation, making it ideal for 24/7 server environments.
Q: Does it support Wake-on-LAN (WoL)?
A: Yes, the RTL8111H chipset supports Wake-on-LAN functionality, allowing you to remotely power on your computer over the network when properly configured in your BIOS and operating system.
