USB 3.0 to Gigabit Ethernet Adapter

This white adapter adds a wired RJ45 network port to any device with a USB 3.0 Type-A socket. It is intended for ultrabooks, notebooks or tablets that lack a built-in Ethernet jack and need a stable wired link for file transfers, video calls or streaming. The short .5 ft cable keeps the dongle close to the host port. Buyers who need a longer reach or a USB-C connection cannot use this model.

Sustained link performance

The adapter runs at full 10/100/1000 Mbps gigabit speeds over the USB 3.0 bus, which provides up to 5 Gbps of bandwidth. Link and activity LEDs show the connection state at a glance. It draws power from the USB port so no external supply is needed, and it remains backward compatible with USB 2.0 and 1.1 hosts at reduced throughput.

Compatibility checklist

Supported operating systems include Windows 8.1, 8, 7, Vista and XP; Mac OS X 10.6 through 10.10; Linux kernel 2.6 or 3.x; and Chrome OS. Windows RT and Android are not supported. The device complies with IEEE 802.3, 802.3u, 802.3ab and 802.3az standards. Verify that your computer has a free USB Type-A port and runs one of the listed systems before ordering.

Questions about this item

Does the adapter generate noticeable heat or noise when used continuously at 1000Mbps?

The unit is USB powered with no fan and a short 0.5 ft cable, so it runs silently and stays cool during all-day gigabit transfers.

My laptop only has USB 2.0 ports — will the 20255 work at reduced speed?

Yes, it is backward compatible with USB 2.0 and 1.1, though the 10/100/1000Mbps Ethernet link will be limited by the USB 2.0 bus bandwidth.

Will the 20255 work with my older Windows 7 desktop and a Cat 5e patch cable?

Windows 7 is listed as supported, and the RJ45 port accepts standard Cat 5e or Cat 6 cables for 10/100/1000Mbps operation.
