USB 3.0 Gigabit Ethernet Adapter

This ESTONE adapter adds a wired Gigabit Ethernet port to any computer with a USB 3.0 Type-A socket. It is aimed at users replacing a failed onboard NIC, adding a second isolated network interface, or moving large files over a stable wired link. The device draws power from the USB bus and requires no external supply.

10/100/1000 Mbps wired throughput

The adapter negotiates at 10, 100 or 1000 megabits per second over a standard RJ45 cable. It implements IEEE 802.3, 802.3u and 802.3ab for full Gigabit operation and supports IEEE 802.3az Energy Efficient Ethernet to reduce idle power. Performance is limited to USB 2.0 speeds when plugged into a USB 2.0 or 1.1 port.

Windows 2000 through 8 and Mac OS 10.6+ support

Driver support covers Windows 2000, XP, Vista and 7/8 in both 32-bit and 64-bit editions, plus Mac OS 10.6 or higher. The package explicitly does not support Windows RT, Android, Wii, Wii U or Nintendo Switch. No additional software or management utilities are mentioned in the supplied data.

Questions about this item

What does the 1000 bit Ethernet rating mean for actual network speed?

The adapter supports Gigabit Ethernet at up to 1000 Mbit/s over the RJ45 port, so file transfers and streaming run at full wired speed when the switch and cabling also support it.

How does the USB 3.0 interface affect the maximum throughput?

The upstream USB 3.0 Type A connection provides enough bandwidth to sustain Gigabit Ethernet without the bottleneck that USB 2.0 would impose, while remaining backward compatible with USB 2.0 and 1.1 ports at reduced speed.

What physical port and cable does this adapter need to work?

It plugs into a standard USB Type A socket on the computer and presents a regular RJ45 jack for a Cat5e or better Ethernet patch cable.
