Add a wired 2.5GbE connection through USB

2.5GBASE-TUSB-C + USB-A adapterRTL8156B33g

The AS-U2.5G2 adds one wired Ethernet port to a compatible computer or supported ASUSTOR NAS. Connect the integrated USB-C lead, or use the included USB-A adapter, then connect an Ethernet cable to your network. Its RTL8156B controller supports up to 2.5Gbps link speed, and the aluminium body weighs 33g. It is USB powered and needs no separate power supply.

Before you order:
For a 2.5GbE link, use a suitable USB 3.2 Gen 1 host connection, a 2.5GbE network port and Cat 5e or better cable. Check the listed operating system and NAS series; ADM 3.5.1 or later is required. When using the USB-A adapter, align the connector triangle with its USB logo as ASUSTOR instructs.

What's in the Box

  • AS-U2.5G2 Ethernet adapter with integrated USB-C cable.
  • USB-C to USB-A adapter and quick installation guide.

What It Means in Practice

  • For faster local file transfers, connect a supported laptop to a 2.5GbE switch and a suitably connected NAS; the entire network path matters.
  • The adapter also negotiates 1Gbps and 100Mbps links for existing networks. Its link speed is not a guaranteed file-transfer speed.
  • Supported systems can install automatically, but some Linux distributions need a driver. DHCP is the default network configuration.

What Will Not Work

  • It does not turn a Gigabit switch port into a 2.5GbE port or increase your internet subscription speed.
  • It is a wired network adapter; it does not add Wi-Fi or function as a standalone router.

Key Features

 
A faster wired link
2.5GBASE-T with automatic negotiation at 2.5Gbps, 1Gbps or 100Mbps connects to both newer and existing networks.
 
Both common USB connectors
The integrated Type-C cable and included Type-A adapter support different host ports without buying a second network adapter.
 
Compact aluminium housing
The 33g aluminium-alloy body dissipates heat and travels easily. Power comes directly from USB.

Frequently Asked Questions

Can I use it on a USB-A computer?
Yes, the box includes a USB-C to USB-A adapter. Use a suitable USB 3.2 Gen 1 connection and follow the connector-alignment instruction for maximum speed.
Will I get 2.5Gbps through my existing Gigabit switch?
The link will negotiate the speed supported by the connected port. A Gigabit switch limits that link to 1Gbps; 2.5GbE needs a matching network port and suitable cabling.
Is a driver never required?
Do not assume that for every OS. The installation guide describes automatic setup on supported ADM, Windows and macOS systems, while some Linux distributions may require a manual driver installation.
Singular Expert Insight
This is useful when the USB port is easier to upgrade than an internal network card. Check the host, switch and NAS together: a faster adapter helps only where the rest of the connection can use it. Ask Singular to check your USB port and network upgrade.
