TP-Link TG-3468 32-bit GB PCIe Network Adapter RTL8168B

TP-Link TG-3468 Gigabit PCIe Network Adapter

Overview

The TG-3468 is a 32-bit Gigabit PCIe network interface card designed to add or replace network connectivity in desktop systems where onboard Ethernet has failed or bandwidth isolation is required. The adapter uses the Realtek RTL8168B chipset and supports 10/100/1000Mbps auto-negotiation, making it compatible with legacy and current network infrastructure without manual speed configuration. Auto MDI/MDIX eliminates the need for crossover cables—plug into any standard RJ45 jack. This is a straightforward remedy for aging surveillance backend servers, workstations running VMS software, or any compute platform requiring reliable, single-port Gigabit access.

Compatibility

The TG-3468 installs in any x1 PCI Express slot on a motherboard running Windows, Linux, or compatible operating systems. It suits general-purpose desktop and light server applications where a single Gigabit port is sufficient. Verify your system has an available PCIe x1 slot; full-height form factor may require clearance verification if your chassis is tight. No external power required—the card draws power directly from the PCIe slot. When integrating into security appliances or NVR platforms, confirm the operating system and driver availability before ordering.

Key Specifications

• Interface: PCI Express x1 (32-bit) — sufficient for Gigabit saturation; no bottleneck at 1000Mbps throughput.
• Speed: 10/100/1000Mbps auto-negotiation — adapts to network conditions without administrator intervention.
• Connector: RJ45 with auto MDI/MDIX — standard cabling; no crossover cable needed.
• Chipset: Realtek RTL8168B — mature, well-supported driver availability across Windows and Linux distributions.
