USB 3.0 to Gigabit RJ45 Adapter G2 by HP — wired Ethernet via USB host interface

The HP USB 3.0 to Gigabit RJ45 Adapter G2 provides wired Ethernet connectivity through a USB host interface. Designed for systems that lack a built-in Ethernet port, this compact adapter enables access to Gigabit Ethernet networks using a USB 3.0 connection. It is compatible with a wide range of laptops, tablets and compact desktop systems that require a stable, wired network link for file transfers, streaming, remote work or network diagnostics.

Advantages

The adapter delivers Gigabit Ethernet performance over a USB 3.0 host interface, offering reliable wired throughput where wireless connections are insufficient or unavailable. Its compact form factor and plug-and-play operation simplify deployment without requiring internal modifications. Hardware-based compatibility with common operating systems ensures consistent network performance and low latency for bandwidth-sensitive tasks.

Suitable for

• Connecting laptops and tablets to wired office or home networks
• Temporary or permanent network access for ultrabooks and compact PCs
• Video conferencing, streaming and large file transfers over a stable connection
• Network troubleshooting and configuration when Wi‑Fi is unavailable or restricted

Key specifications

• Host interface: USB 3.0 (backward compatible with USB 2.0)
• Network interface: RJ45, 10/100/1000 Mbps (Gigabit Ethernet)
• Full- and half-duplex support with auto-negotiation
• Compact external adapter housing for portability
• Power supply via USB host port, no external power required

How to use

Connect the adapter's USB 3.0 plug to an available USB port on the host device and attach an Ethernet cable to the RJ45 port. Operating systems that include native drivers will typically recognize the adapter and establish a network connection automatically; if necessary, install the appropriate driver package for your OS following HP guidance. Once connected, confirm network settings on the host device to ensure proper IP addressing and DNS configuration for the intended network environment.

Recommendations

Use a USB 3.0 port to achieve maximum throughput; while the adapter is backward compatible with USB 2.0, link speeds will be limited by the host interface. For consistent Gigabit performance, use high-quality shielded Ethernet cables and verify switch or router port settings (auto-negotiation recommended). Keep the adapter's connector and cable free of excessive strain to maintain a reliable physical connection.
