USB 3.0 LAN Hub with Gigabit Ethernet 3-Port 1000Mbps RJ45

Combined Gigabit Networking and USB Expansion

The USB 3.0 LAN Hub adds a Gigabit Ethernet port and three USB 3.0 Type-A ports from a single host connection. It uses the Realtek RTL8153 for the network side and a VIA VL812 or GL3510 hub controller for downstream ports. The compact housing measures 85 x 45 x 15 mm and weighs about 60 grams.

The RJ45 port negotiates 10/100/1000 Mbps and supports IEEE 802.3, 802.3u and 802.3ab standards. Auto-MDI/MDIX handles straight-through and crossover cables without manual selection. The three USB-A ports deliver up to 5 Gbps each and remain backward compatible with USB 2.0 and 1.1 devices.

The adapter draws power from the host USB bus, with typical consumption around 165 mA at 5 V when the Ethernet link is active. No external power adapter is required for standard loads. Driver support covers Windows, macOS, Linux and Chrome OS through in-box or vendor-supplied drivers. Operating temperature spans 0 °C to 70 °C.

Key Features

• Gigabit Ethernet via RTL8153
  The Realtek RTL8153 controller supports 10/100/1000 Mbps links with hardware checksum offload.

• Three USB 3.0 Downstream Ports
  Each Type-A port delivers up to 5 Gbps and supplies standard bus power to peripherals.

• Hub Controller Options

  • VIA VL812 or GL3510 hub controller
  • Supports USB 3.0, USB 2.0 and USB 1.1 device fallback
  • Overcurrent protection on downstream ports

• Auto-MDI/MDIX Crossover Detection
  The Ethernet PHY detects cable wiring and configures the pair assignment automatically.

• Bus-Powered Operation
  The unit runs from the host port at roughly 165 mA and needs no wall adapter for normal loads.

• LED Status Indicators
  Link and activity LEDs on the RJ45 port show connection state and traffic.

• Compact ABS Housing
  The 85 x 45 x 15 mm body fits beside a laptop without blocking adjacent ports.
