USB 3.0 Ethernet Adapter ALLNET S215535 with integrated 2 m patch cable, Gigabit LAN

ALLNET S215535 is a USB 3.0 Ethernet adapter with an integrated 2 m patch cable that adds Gigabit LAN connectivity to laptops, desktops and other devices without a built-in RJ45 port. The compact adapter uses a USB 3.0 interface to deliver up to 1 Gbps wired network speed in environments where a stable connection is required for streaming, file transfers, online meetings or network diagnostics.

Advantages

The adapter combines a USB 3.0 connector and a permanently attached 2 m patch cable in a single compact housing to avoid cable clutter and simplify installation. By providing Gigabit LAN throughput it reduces latency and jitter compared with typical wireless connections and supports reliable high-bandwidth activities. Its plug-and-play design minimizes setup time and makes it suitable for temporary or permanent network access.

Suitable for

• Adding wired network access to ultrabooks and laptops without an RJ45 port
• Desktops or mini PCs with limited internal network options
• Video conferencing and VoIP where a stable connection is important
• Large file transfers, backups and media streaming over LAN
• Network troubleshooting and temporary connections in offices or fieldwork

When it may not be suitable

This adapter requires an available USB 3.0 port on the host device to achieve full Gigabit speeds; on USB 2.0 ports throughput will be limited by the USB interface. It is not a replacement for managed switches, PoE requirements or advanced enterprise network features such as VLAN tagging, unless those functions are provided by the connected network equipment.

Key specifications

• Interface to host: USB 3.0 (backward compatible with USB 2.0)
• Network speed: up to 1 Gbps (Gigabit Ethernet)
• Integrated cable: 2 m permanently attached Ethernet patch cable with RJ45 connector
• Connection type: RJ45 (10/100/1000 Mbps auto-negotiation)
• Form factor: compact external adapter with integrated cable for reduced clutter

How to use

Connect the USB 3.0 plug of the adapter to an available USB port on your computer and insert the integrated RJ45 connector into a network socket, switch or router. Allow the host operating system to detect and install any necessary drivers; many modern systems provide built-in driver support for USB Ethernet adapters. After driver installation, configure network settings as required by your environment (DHCP or static IP) and verify the link speed and connectivity in the system network settings.

What to consider before purchase

• Check that your device has a USB 3.0 port to achieve full Gigabit performance; USB 2.0 will limit speeds.
• Confirm cable length (2 m integrated) suits your workspace layout and connection points.
• Ensure your operating system has drivers for USB Ethernet adapters or be prepared to install drivers if necessary.
• Verify that no advanced managed network features are required from the adapter itself (such features are typically provided by switches or routers).

Usage recommendations

For consistent Gigabit performance, connect the adapter to a USB 3.0 port on the host and to a Gigabit-capable switch or router. Keep the integrated cable free from tight bends and avoid placing heavy objects on it. If you experience reduced speed, check the host USB port capability and verify the link speed in the operating system network settings.
