USB 3.0 Gigabit Ethernet Adapter

This USB 3.0 to RJ45 adapter converts a spare USB 3.0 port into a standard gigabit LAN connection. It auto-negotiates 10, 100 or 1000Mbps bandwidth for high-speed wired networking. The compact dongle provides reliable internet access for computers lacking a built-in Ethernet port.

Suits laptops and mini PCs without native Ethernet

Ideal for MacBook, notebook or desktop users who need a stable wired link for gaming, video calls or large file transfers. It also works as a replacement for a faulty onboard port. Not for buyers who require multi-gigabit speeds beyond 1000Mbps or need Power over Ethernet functionality.

Handles 1000Mbps wired throughput

Comfortably manages gigabit-class downloads, streaming and low-latency gaming over copper cable. The anti-interference circuit maintains signal quality in electrically noisy environments. Headroom ends at the 1000Mbps ceiling; aggregating multiple adapters or using faster USB standards would be needed for higher bandwidth.
