Product Features

Get Connected

For the fastest, most reliable network speeds, add a 2.5 Gigabit Ethernet (2.5GbE) connection to any system over USB Type-A. Improve upon or replace your wireless connection, or just add another or faster network port to your device.

Plenty Of Speed

This 802.3bz (2.5GBASE-T) compliant adapter can deliver network speeds of up to 2.5Gbps at 100 meters or more when using CAT 5e or better cabling and compliant network equipment. It’s also backward compatible for older networks.

Connect When Ready

The adapter connects to any system with a free USB Type-A port, able to reach maximum network speeds with 5Gbps (USB 3.2 Gen 1x1) and newer ports. The adapter is also backward compatible with 480MBps (USB 2.0) for legacy systems.

Built Practical

This lightweight enclosure is designed to be portable with an aluminum alloy body, improving durability and heat dissipation for traveling and prolonged transfers. It’s also bus-powered with clear status LEDs for easy operation.

Fast and Reliable

Got an old system that needs a faster network connection? Spotty wireless? Or maybe you just want to add another line to your favorite server. The Sabrent USB-A 3.0 to 2.5 Gigabit Ethernet Adapter lets you convert any USB Type-A port into a 2.5GbE Ethernet port for a fast and reliable network connection. Although made for maximum speed using 5Gbps (USB 3.2 Gen 1x1) ports and faster networks, the adapter is backward compatible for older 480Mbps (USB 2.0) ports and machines as well as slower devices in a network chain. It’s an easy upgrade either way.

 

The adapter is fully 802.3bz (2.5GBASE-T) compliant which means speeds of up to 2.5Gbps at lengths of up to at least 100 meters, if the proper equipment is used. CAT 5e or newer cabling with multi-gig networking devices ensure the smoothest and fastest experience. The adapter is designed to be portable, durable, and cool-running thanks to its aluminum alloy body design, in order to allow for consistent and sustained operation. It’s also bus-powered with clear status LEDs to make things even easier. Connect and start transferring!

What are some ways to get the best networking performance from the adapter?

The adapter should be used with an updated driver and with a 5Gbps or faster USB port. Any networking devices in the chain, including the cable, should be able to connect at 2.5GbE speeds or faster. Internet speeds are dependent on your ISP. The actual transfer rate may be lower than the theoretical maximum of ~300 MBps.
 

What are some best practices for adapter use?

The adapter should never come in contact with liquids and should not be used in a very dry or very humid environment. High external temperatures and direct sunlight exposure could overheat the adapter or host device and should be avoided. The integrated cable should not be bent or folded during installation or operation. The adapter and any attached Ethernet cable should not be pulled or left hanging.

Is there anything else to know about the adapter?

When plugging in the adapter, it can take up to ten seconds or more before a connection is acknowledged. It is hot-swappable but patience may be required. If performance is degraded, check the LED status lights to make sure the negotiated speed is as expected. Customization of settings in the host operating system for the adapter is possible and may be necessary for some setups.

Is there a way to improve VPN performance with this adapter’s chipset?

If you are using IKEv2 and still have performance issues, please set receive buffers to 128 and receive URBs to 64. Transmit buffers should be set to 64 and transmit URBs to 32. This should optimize the connection.
