Dual Port Gigabit Ethernet Card PCIe Adapter – High-Performance Network Interface

Boost your network bandwidth and reliability with the Dual Port Gigabit Ethernet Card. This PCIe network interface card delivers two 10/100/1000 Mbps RJ45 ports, letting you connect your desktop PC to multiple networks or create redundancy for mission-critical applications. Built around the RTL8111G chipset and compliant with PCIe 2.0, it supports Jumbo Frames, 802.1Q VLAN tagging, and Wake-on-LAN (WoL). A rugged alloy heatsink keeps the card cool under heavy load, ensuring stable performance whether you’re setting up a high-speed LAN, server, or embedded communications platform.

Key Features of the Dual Port Gigabit Ethernet Card

• Dual 10/100/1000 Mbps Ports: Two independent Ethernet connections for link aggregation or network segmentation.
• RTL8111G Chipset: High-performance controller ensuring low latency and reliable throughput.
• PCI Express 2.0 x1 Interface: Backward compatible with x1, x4, x8, and x16 slots for flexible installation.
• Advanced Cooling: Imported alloy heatsink for efficient heat dissipation and extended component lifespan.
• Jumbo Frames & VLAN Support: Handles up to 9 KB frames and 802.1Q VLAN tagging for optimized network traffic management.
• Wake-on-LAN (WoL): Remotely power on your system over the network.
• Low-Profile Bracket Included: Fits both standard and small form-factor chassis.

Why Choose a Dual Port Gigabit Ethernet Network Card?

Modern applications—from virtualization and file servers to VoIP and video streaming—demand robust network performance and redundancy. By installing a dual port PCIe Ethernet adapter, you can:

• Increase Throughput: Combine both ports via link aggregation (IEEE 802.3ad) for up to 2 Gbps of bandwidth.
• Enhance Reliability: Failover support maintains connectivity if one link drops.
• Network Segmentation: Connect to separate VLANs or subnets directly.
• Remote Management: Use Wake-on-LAN to power up systems for maintenance tasks without physical access.

People Also Ask

What is link aggregation on a dual port NIC?

Link aggregation (802.3ad) combines two Ethernet ports into a single logical link, effectively doubling throughput and providing redundancy if one port fails.

Can I install this in a small form-factor PC?

Yes. The package includes a low-profile bracket so you can install the card in both standard and compact chassis.

Does this card support Linux?

Absolutely. The RTL8111G chipset is supported by most Linux kernels (2.6 and above), with native driver support—no additional downloads required.

Technical Specifications

Installation and Setup

Setting up your dual port NIC is straightforward:

1. Power down and open your PC’s chassis.
2. Insert the card into any available PCIe slot (x1–x16).
3. Screw in the bracket—standard or low-profile—to secure the card.
4. Close the chassis and power on your PC.
5. On most systems, drivers install automatically. If prompted, download the latest RTL8111G driver from your OS vendor.

Network Configuration Tips

• Enable Jumbo Frames: In your network adapter settings, increase MTU to 9000 for large-packet transfers.
• Configure VLANs: Tag traffic to separate voice, data, and management networks.
• Set up Link Aggregation: On managed switches, create an LACP group to bond both ports.

Use Cases and Applications

This dual port gigabit NIC is perfect for:

• File and Print Servers: Higher throughput for concurrent users.
• Virtualization Hosts: Dedicated networks for VMs and management interfaces.
• Workstations: Dual-network interfaces for isolated development and production LANs.
• Embedded Systems: Industrial PCs requiring reliable Ethernet connectivity.
• Small Business NAS: Link-aggregated access for faster backups.

Whether you’re upgrading a desktop PC, building a new server, or expanding a workstation’s network capabilities, the Dual Port Gigabit Ethernet Card offers flexibility, performance, and reliability. With support for Jumbo Frames, VLAN tagging, Wake-on-LAN, and an efficient heatsink design, it meets the demands of modern networking environments. Install it today and experience faster data transfers, greater redundancy, and enhanced control over your network traffic.
