Manufacturer description
The uni USB to Ethernet Adapter turns a single USB-A port into a four-port workstation hub, pairing a 10/100/1000Mbps RJ45 jack with three USB 3.0 ports rated up to 5Gbps. If your laptop's Wi-Fi keeps stalling mid-transfer, the wired gigabit link gives you a stable connection instead of a flaky wireless card; pair it with a CAT6 or better cable to actually hit 1Gbps. The three downstream USB 3.0 ports run simultaneously, so a flash drive, mouse, keyboard, webcam, and printer can all stay connected without swapping cables. Data only, though, since the hub does not pass through charging. uni…

Frequently Asked Questions
Do I need to install drivers for this adapter?
No on ChromeOS, Mac OS X 10.5 or later, Linux, and Windows 8/7/Vista/XP/10 - it is plug and play. Windows 11 is the exception and does require a driver.
Will it actually deliver a full 1Gbps connection?
The RJ45 port supports 10/100/1000Mbps. To reach 1Gbps you need to connect with a CAT6 or better Ethernet cable; slower cable categories will cap the link below gigabit.
Can I charge my laptop through the USB ports?
No. The three USB 3.0 ports are for data only at up to 5Gbps - charging is not supported, so keep your laptop on its own power adapter.
Does it work with an M2 MacBook or a Nintendo Switch?
No. uni lists both the M2 chipset and the Nintendo Switch as unsupported. It does work with iMac, XPS, Surface Pro, Chromebook, and standard PCs and laptops.
Why does my wireless mouse stutter when the hub is plugged in?
USB 3.0 hubs can interfere with 2.4GHz Wi-Fi and Bluetooth. Move the device away from the computer and the display hinge, and switch Wi-Fi to the 5GHz band where possible.
What warranty comes with it?
uni includes an 18-month warranty plus 24/7 customer service, with most issues resolved within 12 hours according to the manufacturer.

- 【📌Note】Wi-Fi and Bluetooth devices operating in the 2.4GHz band to have issues communicating with your computer. Here are some tips to avoid this issue: 1. If your USB device has a cable long enough that you can move the device, place it away from your computer—and make sure not to place it behind your computer, or near the hinge of its display. 2. To avoid interference on the 2.4GHz band using Wi-Fi, try using the 5GHz. Bluetooth always uses 2.4GHz, so this alternative isn't available for Bluetooth. Try to cover the USB-A connector with tinfoil, it may help with this situation.
