Adattatore USB 3.0 a RJ-45 Ethernet Dell FM76N Gigabit — adattatore di rete USB 3.0 per LAN cablata

Dell FM76N is a USB 3.0 to RJ-45 Gigabit Ethernet adapter that enables wired network connectivity through a USB 3.0 port. It is intended for laptops and desktops that lack a built-in Ethernet jack, providing a simple way to connect to wired LANs with standard Cat5e or Cat6 cabling. The adapter supports gigabit speeds and plug-and-play operation with commonly used operating systems to deliver stable, low-latency network access for everyday tasks.

Advantages

The adapter provides a compact and portable means to add a Gigabit Ethernet port via USB 3.0 without opening the chassis or relying on external docking stations. It supports high-throughput wired connections that are typically more stable and have lower latency than wireless networks, which benefits large file transfers, streaming and real-time communications. The plug-and-play design minimizes setup time and reduces the need for additional configuration for most operating systems.

Suitable for

• Connecting laptops or ultrabooks without an Ethernet port to wired office or home networks
• Establishing stable connections for video conferencing and VoIP calls
• High-speed file transfers and backups over local networks
• Temporary or permanent network access for desktops where internal ports are unavailable

Key specifications

• Interface: USB 3.0 (backward compatible with USB 2.0)
• Network port: RJ-45 (10/100/1000 Mbps Ethernet)
• Supported cable types: Cat5e, Cat6
• Data transfer rate: Up to Gigabit Ethernet speeds
• Form factor: Compact external adapter with integrated USB cable
• Power: Bus-powered via USB port (no external power supply required)

How to use

Plug the adapter’s USB 3.0 connector into an available USB port on your laptop or desktop. Connect an Ethernet cable from your network switch, router or wall outlet to the adapter’s RJ-45 port. Most modern operating systems will detect the adapter automatically and configure network settings via DHCP. If necessary, install the appropriate driver provided by the operating system or device manufacturer to enable full functionality.

Recommendations

For reliable gigabit performance, use Cat5e or Cat6 cabling and connect to a Gigabit-capable switch or router. Prefer USB 3.0 ports on the host device to achieve maximum throughput; when using USB 2.0, expect reduced speeds. Keep the adapter and cable clear of heat sources and avoid excessive bending of the integrated cable to prolong service life.
