short cable make it easy to carry and place on a desk or at a portable workstation.
Backward Compatible with USB 2.0/1.1 Devices

FAQs
Do I need to install drivers for the Ethernet adapter?
In most modern OS versions it’s plug-and-play. Some older systems may require a driver download from TP-Link’s website.
Can I use all USB ports and Ethernet simultaneously?
Yes — the hub supports use of the three USB ports and the gigabit Ethernet port at the same time. However, your host’s USB bandwidth may limit shared performance.
Will it work with my USB-C laptop?
Yes — if you use a USB-C to USB-A adapter or cable, but your laptop must support USB-A host mode. For USB-C specific hubs check those models.
Is the Ethernet port full gigabit?
Yes — the RJ-45 port supports 10/100/1000 Mbps speeds, giving you full gigabit network access when connected.
