  • Adds a 2.5 Gbps network port through a USB 3.0 Type-A connection
  • Backward compatible with 10/100/1000 Mbps networks for flexible deployment
  • Driver-free on macOS and Windows 8/10/11 for instant use
  • RTL8156B chipset delivers stable, low-latency data streaming across OS platforms
  • Supports Wake-on-LAN and advanced power management for efficient operation

USB 3.0 to 2.5G Ethernet Adapter

The Vszerda USB 3.0 to 2.5G Ethernet Adapter adds a 2.5 Gigabit RJ45 port to any computer with a USB 3.0 Type A socket. It uses the RTL8156B chipset and works with Windows 8, 10, 11, macOS and Linux without extra drivers. Windows XP and 7 require a driver install. The adapter is suited for replacing a faulty onboard NIC or adding a second routed interface.

Sustained 2.5 Gbps over USB 3.0 bus

The adapter runs at 2.5 Gbps when connected to a USB 3.0 port, delivering 2.5 times the throughput of 1 Gbps Ethernet. It negotiates down to 1000, 100 or 10 Mbps automatically. On a USB 2.0 port the link is limited to 10/100 Mbps. The IEEE 802.3 bz compliant controller maintains stable streaming and supports Wake-on-LAN plus advanced power management for lower idle draw.

USB 3.0 Type A host requirement

Full 2.5 Gbps speed needs a USB 3.0 host port; USB 2.0 ports cap the link at 100 Mbps. Buyers whose systems only offer USB 2.0 will not reach the rated throughput. The device draws power from the bus and requires no external supply.

Questions about this item

Does the RTL8156B chipset run hot or draw much power when the adapter sustains 2.5 Gbps all day?

The adapter uses advanced power management features on the RTL8156B chipset to save power and maintain stable data streaming during continuous high-speed transfers.

What must I already have on my computer for the USB 3.0 Type-A plug to deliver 2.5 Gbps instead of falling back to 10/100 Mbps?

You need a USB 3.0 port; the adapter is compatible with USB 2.0 but speed will be limited to 10/100 Mbps on that older interface.

Will this RJ45 converter negotiate 2500 Mbps with my older Cat 5e patch panel and 1 Gbps switch?

The adapter is backward compatible with 2500/1000/100 Mbps networks and follows the IEEE 802.3 bz standard, so it will auto-negotiate the highest speed the link supports.
