This WORKS with Proxmox 7.1. Outstanding!

Reviewed in the United States on January 24, 2022

This dual port Ethernet adapter WORKS with "ProxmoxVE 7.1-2".

I plugged it into the USB port before power on. Then during the initial installation of ProxmoxVE 7.1, this USB Ethernet adapter was immediately recognized and configured properly within ProxmoxVE.

It works perfectly (as if it were an internal PCIe adapter). WELL DONE!

Easy to install, outside case runs warm

Reviewed in the United States on July 19, 2023

The outside case temperature at one point was measured as 110 DegF in an ambient room temperature of about 72 DegF. Too warm for our point of view. Easy to use on our Linux SBC.

Adds two Ethernet ports, indiviudally addressible, to a RaspberryPi running OpenWRT

Reviewed in the United States on January 22, 2024

Style: USB 3.0 to Dual Gigabit EthernetVerified Purchase

At a high level this USB device does exactly what it is supposed to - it adds two independently addressable Ethernet ports.

In my use case I am using this device to provide WAN1 and WAN2 to a RaspberryPi 4B running OpenWRT (23.05.2), and using the mwan3 software to manage the traffic between each interface.

Things to note:
The Pi 4B with an Argon ONE case, no ethernet traffic and no load, draws 3.3 watts.
Adding the adapter, and utilizing both interfaces, takes the power consumption to ~6.8-7.1 watts (so just over double the power needs).
The device uses the RealTek RTL8153 chip. You will need to install the RTL8152 driver on Linux (kmod-usb-net-rtl8152). Once installed the device works as expected.

The unit I have is warm to the touch but not at a worrisome level (other reviews have raised concern about the level of waist heat).

For my use case (add a 2nd and 3rd NIC to an inexpensive Linux device with a minimum of USB port consumption) this adapter is exactly what is needed. If your need is the same then I wholeheartedly recommend it.

Not "plug-and-playable"

Reviewed in the United States on November 28, 2013

Style: USB 3.0 to Gigabit EthernetVerified Purchase

Product works fine but when i use it with my Surface Pro (1st Gen), it requires drivers. Previously the posting of this product stated that it was plug-and-play.

But generally, the product works as currently specified and after months of usage, I have not encountered any problems yet.

For the price, I feel that this product is with the value and should consider purchasing it if you need the RJ45 point for your mobile devices.

Works great on a Macbook Pro

I've got an old Macbook Pro that I use to control some audio systems at work. I'm using the onboard ethernet port to control and audio console and I'm using the USB adapter to get internet access and run Dante Controller. Works great, haven't had an issue yet. Works just as it is supposed to.

Two separate nics literally

Reviewed in the United States on August 22, 2022

Style: USB 3.0 to Dual Gigabit EthernetVerified Purchase

I usually don’t write reviews but this product was exactly what I was looking for. It gives you two separate NICs with separate mac addresses. I work with setting up networks and this adapter really came in handy. While troubleshooting I can setup a static on one nic and DHCP the other. This should be an essential adapter for everyone Network technician.
What would make this product more appealing is a usb c to usb 3 adapter attached to it. The Mac users will be able to use it as well.

Terrible for gaming, huge lags!

Reviewed in the United States on July 24, 2014

Style: USB 3.0 to Gigabit EthernetVerified Purchase

I'm sorry to say that I couldn't give this product anything better than 1 star. On the first day of use, this adapter results in lags up to 7.6 sec, while my old router have lags around 0.15.
I also ran a speed test for this adapter, it has a Ping of 4, while my router controls Ping less than 2. I will consider to return this product if situation still continues.

Works with Linux with a little extra effort

Reviewed in the United States on December 11, 2013

Style: USB 3.0 to Gigabit EthernetVerified Purchase

I use this as a second wired Ethernet interface for network diagnostics with my Linux laptop. Works well, no problems, and doesn't look or feel cheap like some other USB Ethernet adapters I have used.

I use it with Ubuntu Linux 12.04. It didn't work out of the box, but the manufacturer has a link to the driver to use. It built and worked cleanly, so overall a good Linux experience for bleeding edge hardware with an aging distro.

Dual Gigabit Ethernet Adapter will run both ports at full speed

Reviewed in the United States on May 20, 2020

Style: USB 3.0 to Dual Gigabit EthernetVerified Purchase

The item I purchased was the DUAL Gigabit Ethernet Adapter and in the attached picture you can see it attached to a Raspberry Pi 4 running as a transparent bridge and monitoring my Internet connection for bandwidth usage. The adapter can run either one port or both ports at full speed getting a full Gigabit on each (ok, about 980Mbit which is the true maximum you can get). It will run on Mac, Linux, and Windows with no issues. Only drawback is the Mac Address labels do not indicate which port they apply to so you have a little discovery to do to figure that out.

Works Great, Perfect ADDON

Reviewed in the United States on August 4, 2017

Style: USB 3.0 to Dual Gigabit EthernetVerified Purchase

Bought this for use in a Media Server and was able to configure each port individually or bridge them if needed. I'm currently using each port individually so that my home or my internet streaming can use/access my server and it's made a huge difference, no more pausing when streaming. Great product and I've always had excellent luck with Vantec products, this is just one more on my list. Thank you Vantec!
