Did exactly what I needed, in the way I needed it to.

Reviewed in the United States 🇺🇸 on August 6, 2022

Color: BlackStyle: BlackVerified Purchase

I was having some trouble with my onboard ethernet port, so rather than run it all down, or replace the motherboard preemptively, I just decided to go this route. I've had good luck with USB Ethernet adapters before, so I wasn't too worried. Fortunately, this one presents itself to the system as two separate interfaces, so you could use this if you wanted to have your machine function as a router, or some other dual-homed system. In my case, I just bonded the two interfaces into one, and increased the performance. It works perfectly.

Excellect choice if you do no have a lan connection on your laptop

Reviewed in the United States 🇺🇸 on June 21, 2017

Color: BlackStyle: BlackVerified Purchase

I had purchased a Cable Matters USB3.0 to RJ45 Gigabit Network Adapter and it worked Great for Windows 10 and I thought it might work for 2012R2. I contacted cable matters and they said it would work. It did not. I looked into this Star Tech USB3.0 to Dual Port Gigabit and it also said it worked for Windows 10 but did not say it would work for Server 2012R2. I left a message for Star Tech and they said it would work so purchased it. Just received it today and plugged it in on my Server 2012R2 and it worked without using the disk. The system found the driver and installed it automatically. I ran a network speed test on the star tech USB 30 to Ethernet vs a gigabit lan network connection to the internet thru Comcast and got similar connection speeds with both. The only downfall is the size of the adapter as you need room for 2 lan connections

I needed the ability for my Microsoft Surface Pro 6 tablet to connect to two different networks. This devices does the job perfectly. Really happy that it has a USB pass-thru port too.

The only caveat I have had with this device is the inability to using wake-on-lan functionality. If it does work in this setup, I don't know how.

Works fine for link aggregation at full speed

Reviewed in the United Kingdom 🇬🇧 on December 13, 2021

Color: BlackStyle: BlackVerified Purchase

Despite what a previous reviewer stated, this device works just fine for link aggregation at near full speed.

Link aggregation works by apportioning traffic to multiple destinations to different ports of the aggregated link based on a hash of the destination MAC and IP addresses, so traffic to two destinations could each use a different port and get the full speed of that port. It provides no throughput benefit for a single destination host.

To properly test throughput over all ports of the aggregated link, you need to send traffic to two or more destination addresses at the same time. I ran such a test using iperf3 to two destinations with consecutive IP addresses (10.0.1.90, 10.0.1.91), but it still used only one port according to traffic counters on my switch, resulting in only about 460Mbps throughput to each host. When I changed the destination host's address from .91 to .92, this resulted in test traffic going via separate ports and I got close to full speed through both ports simultaneously: 110 MB/sec or 920Mbits/sec. Link aggregation was working as expected.

The USB3 gigabit chips used in this adapter are ASIX AX88179, which are well supported by Linux.

Whether using link aggregation or not, this is a useful adapter to have.

Great for connecting to additional networks but not for Link Aggregation

Reviewed in the United Kingdom 🇬🇧 on October 5, 2019

Color: BlackStyle: BlackVerified Purchase

As my headline suggests this will work and works well for for connecting you a 1Gbps to a single network or 1Gbps to another network. However it doesn't work for link aggregation. I have tested this in all 4 possible combinations:
Link aggregation setup on the switch + Link aggregation setup in windows
Link aggregation setup on the switch + No link aggregation setup in windows
No link aggregation setup on the switch + Link aggregation setup in windows
No link aggregation setup on the switch + No link aggregation setup in windows

Each time pulling files from 2 different network locations which has throughput of more than 2Gbps connectivity it will only pull single or dual files at a total of 1Gbps (110MB/sec). So don't buy if you are looking to double your speed but if you want to connect to more than 1 network at once with Ethernet it's great.

Bought 2. Running on two HP DL20 G9's with ESXi 6. Needs the VIB from VirtuallyGhetto (Google it) but takes 2 minutes and a reboot, a cracking setup - I now have 4 x 1Gbs NICs. Supports LACP, Jumbo Frames (4000k max, not 9500k), fast, - 2 x 1Gbs will in no way flood a USB 3.0 port running at 5Gbs. Very happy bunny. And its on Prime.

Doesn't work with any Linux distro that isn't 4+ years old

Reviewed in the United Kingdom 🇬🇧 on October 3, 2021

Color: BlackStyle: BlackVerified Purchase

Bought this for my Raspberry Pi 4, but it sabsolutely useless - official StarTech driver won't install, so it won't work. Looking into the details it turns out they support 'Linux Kernel 2.6.25 to 4.11.x LTS Versions only', which basically means they don't support any Linux distro released since July 2017 (when 4.12.x came out). Falsely sold as compatible with Linux in my opinion.

Reviewed in the United Kingdom 🇬🇧 on January 5, 2016

Been using this in conjunction with a throwing star lan-tap from Hak5 to monitor the connection between my firewall and modem passively. This requires two spare ethernet ports and my ultrabook has none. But using this and wireshark running on linux, I can collect passively from both in/out ports at the same time!!!

Couldn't get it to work the same way on my windows box, but not fussed about that.
