USB 2.0 Ethernet adapter for wired connectivity

This USB 2.0 to Ethernet adapter adds a wired RJ45 network port to laptops and desktops that lack one. It suits users who need a stable cable connection for video calls, file downloads or streaming on Windows 7, 8, 10 or XP. The compact dongle uses a Realtek RTL8153 chip and a short 0.15 m cable.

USB 2.0 bus limits throughput to 100 Mbps

The USB 2.0 interface caps the practical link speed at 100 Mbps even though the RTL8153 controller supports gigabit rates on USB 3.0. Real-world throughput will not exceed the 100 Mbps ceiling, so the adapter cannot saturate faster internet plans or local gigabit networks. Latency remains low for typical office and home tasks.

Handles 100 Mbps links; runs out at gigabit demand

The adapter comfortably handles standard 100 Mbps broadband, video conferencing and moderate file transfers. It runs out of headroom when the upstream connection exceeds 100 Mbps or when moving large datasets across a gigabit LAN. Buyers needing full gigabit throughput should choose a USB 3.0 model instead.

Questions about this item

Should I pick the USB 2.0 or USB 3.0 version for my laptop?

Choose USB 2.0 for 100Mbps wired links on older ports; choose USB 3.0 for 1000Mbps gigabit speeds if your device has a blue USB 3.0 socket.

What real-world speed will the 100Mbps rating deliver on my PC?

The RTL8153 chip drives the RJ45 link at 100Mbps full duplex, so large downloads and video calls run at near-wire 100Mbps without the variability of Wi-Fi.

Does the USB 2.0 interface limit the 100Mbps Ethernet port in practice?

USB 2.0 bulk endpoints sustain well over 100Mbps, so the 100Mbps Ethernet PHY remains the bottleneck and you get the full rated throughput.
