This article covers 5Gb Base-Tネットワークカード.

## Overview
The NICGIGA 5Gb Base-T Network Card is a PCIe x1 Ethernet adapter powered by the Realtek RTL8126 controller, delivering up to 5 Gbps wired connectivity. It supports automatic fallback to 2.5 Gbps, 1 Gbps, and 100 Mbps, making it a versatile upgrade for desktops and servers. Wake-on-LAN is also supported, adding convenience for remote management.

## Connectivity & Compatibility
This card fits into any PCI Express x1, x4, x8, or x16 slot and is compatible with Windows 10/11, Windows Server, and Linux. It negotiates speeds automatically with 5GBASE-T, 2.5GBASE-T, 1000BASE-T, and 100BASE-TX networks. Both standard and low-profile brackets are included, allowing installation in mini-tower cases. Note that legacy PCI slots are not supported.

## Product Info
The manufacturer offers lifetime technical support. The package includes the NIC, standard and slim brackets, and a driver CD/download. Positioned as an entry-to-mid-range solution, it offers excellent value for users seeking affordable 5 Gbps networking.

## Best Use Cases
- Home server or NAS owners who need more than gigabit speeds for large file transfers. The 5 Gbps interface significantly reduces transfer times, but a compatible switch and Cat6 or better cabling are required.
- Creative professionals or remote workers with a 5 Gbps-capable office network. Wired connectivity ensures low latency for VPN and remote desktop sessions. If your internet plan is under 1 Gbps, the card may be overkill.
- Users upgrading older PCs to faster wired networking without replacing the motherboard. As long as a PCIe slot is available, this card provides a cost-effective 5 Gbps upgrade path. Avoid if your system only has legacy PCI slots.
