USB 3.0 2.5 Gbps Ethernet Adapter

This Vszerda adapter adds a 2.5 Gbps RJ45 port to any computer with a USB 3.0 Type A socket. It uses the RTL8156B chipset and works with Windows, macOS and Linux without extra drivers on modern systems. The device suits users who need a faster wired link than standard Gigabit Ethernet or who must replace a faulty onboard port.

Check your USB port and operating system

Full 2.5 Gbps throughput requires a USB 3.0 connection; on USB 2.0 the link falls back to 10 or 100 Mbps. Windows XP and Windows 7 need a manual driver install, while Windows 8, 10, 11 and macOS are plug-and-play. Verify that your cabling and switch support 2.5 Gbps or the adapter will negotiate down to 1000 or 100 Mbps.

Thermals noise and power draw

The adapter draws power from the USB bus and has no fan, so it runs silently. The RTL8156B chipset includes advanced power-management features that reduce consumption during idle periods. In normal operation the enclosure stays warm to the touch but does not throttle, and Wake-on-LAN remains active while the host is asleep.
