❓ Frequently Asked Questions
Q: What chipset does this network card use?
A: This network card uses the Realtek RTL8111H chipset, which is an industry-proven, reliable gigabit ethernet controller with excellent driver support across Windows, Linux, and macOS platforms.
Q: How many ethernet ports does this card have?
A: This card features 4 independent gigabit ethernet ports (RJ45), each capable of 10/100/1000Mbps speeds with auto-negotiation. All four ports can be used simultaneously.
Q: What PCIe slot does this network card require?
A: This card uses a PCIe x1 interface but is compatible with x4, x8, and x16 slots. It will work in any available PCIe slot on your motherboard.
Q: Is this network card compatible with Linux?
A: Yes! The RTL8111H chipset has excellent Linux support with drivers included in the kernel (version 2.6+). It works out-of-the-box with Ubuntu, Debian, CentOS, Fedora, pfSense, and OPNsense.
Q: Can I use this card in a small form factor (SFF) computer?
A: Absolutely! The package includes both a standard bracket and a low-profile bracket, making it compatible with both full-size and small form factor cases.
Q: What is the maximum speed of each port?
A: Each of the 4 ports supports gigabit ethernet speeds up to 1000Mbps (1 Gbps). The ports also support 10Mbps and 100Mbps connections with automatic speed negotiation.
Q: Does this card support link aggregation (LACP/bonding)?
A: Yes, you can configure multiple ports for link aggregation (LACP) or bonding to increase bandwidth and provide redundancy. This requires compatible switch hardware and proper OS configuration.
Q: Can I use this for a NAS or file server?
A: Yes! This card is ideal for NAS and file server applications. You can dedicate different ports to different network segments for improved performance and security.
Q: Do I need to install drivers?
A: Yes, drivers are required for all operating systems. Please download the RTL8111H driver package from the link provided above. The package includes drivers for Windows, Linux, and macOS. Installation instructions are included in the user manual.
Q: Can I use this card for a pfSense or OPNsense router?
A: Absolutely! This card is perfect for building custom routers and firewalls with pfSense, OPNsense, or similar platforms. You can use the multiple ports for WAN, LAN, DMZ, or other network zones.
Q: What is the power consumption of this card?
A: The card draws power directly from the PCIe slot (3.3V/12V) and has low power consumption, typically under 5W at full load. No additional power connectors are required.
Q: Does this card support jumbo frames?
A: Yes, the RTL8111H chipset supports jumbo frames (up to 9KB), which can improve network performance for large file transfers in compatible network environments.
