USB 3.0 verkkosovitin ALLNET ALL-NC-2G-102-USB-A 2x Gigabit Ethernet ja 1x USB-keskitin

The ALLNET ALL-NC-2G-102-USB-A is a USB 3.0 network adapter that adds two Gigabit Ethernet interfaces and one integrated USB hub port to a computer via a USB-A connection. It enables wired network connectivity for laptops or desktops that lack built-in Ethernet ports, supports Gigabit data rates for high-speed transfers, and provides an extra USB port for connecting peripherals. The compact adapter is intended for network expansion, multi-network configurations or as a failover option where reliable wired connections are required.

Advantages

This adapter delivers two Gigabit Ethernet ports over a single USB 3.0 connection, allowing simultaneous use of multiple wired networks with minimal configuration. The built-in USB hub port preserves one USB-A slot on the host device for peripherals. The device supports full-duplex Gigabit throughput where the host and network allow, offering low-latency wired performance compared with wireless alternatives. Its plug-and-play design reduces setup time on supported operating systems and the compact housing is suitable for mobile and desktop use.

Suitable for

• Adding wired Gigabit Ethernet to ultrabooks, tablets or laptops without Ethernet ports
• Network redundancy and failover between two separate wired networks
• Segregating traffic for different networks (e.g., office and guest or test and production)
• Temporary wired connections in meeting rooms, field sites or mobile workstations
• Connecting a USB peripheral while maintaining one or two wired network links

Key specifications

• Interface to host: USB 3.0 (USB-A)
• Network interfaces: 2 × Gigabit Ethernet (RJ45) supporting 10/100/1000 Mbps
• Integrated USB hub: 1 × USB-A port for peripherals
• Operation mode: full-duplex Ethernet with auto-negotiation and auto MDI/MDIX
• Compatibility: suitable for laptops and desktops with USB 3.0 ports; backward compatible with USB 2.0 at reduced performance
• Physical: compact external adapter housing for desktop or mobile use

How to use

Connect the adapter to an available USB-A port on your computer and allow the operating system to detect and install the necessary drivers. Plug Ethernet cables into the two Gigabit Ethernet ports to establish wired network links and connect a peripheral to the integrated USB-A hub port if needed. Configure network settings in the host operating system to assign IP addresses (DHCP or static) and adjust routing or interface priorities if you intend to use both network interfaces concurrently for redundancy or traffic segregation.

Recommendations

Use a USB 3.0 port for optimal Gigabit performance and avoid connecting bandwidth-heavy USB devices to the same host controller when maximum network throughput is required. Ensure proper ventilation around the adapter and avoid excessive cable strain. For multi-network setups, verify routing and firewall rules on the host to prevent unintended traffic between networks.
