Works Great On My Server
I’m using this on an older home server that is limited to 1GBPS Ethernet. This adapter has worked great and has proven to be reliable on my server. I was able to assign a static IP to it without any issues and has been working fine nonstop for a few months at this point. Being able to easily move it or connect it to a laptop is also great in case you need that functionality. Overall, I highly recommend it.

Works great
I tested this adapter between two computer using iperf and was able to get max of 1.89Gbits between them. I am not sure why it didn’t get the full 2.5Gbits but its still better than 1Gbits. My computers are a few years old and i am not sure what USB-C speed I have on my computers so It may be my setup. Ether way i am happy with this adapter.

Excellent, FAST!
This is a USB 3.1 ethernet adapter dongle by ULANSeN. It features a convertible USB-A/USB-C plug, so it can be plugged into whichever size USB port you have available. It appears to be very well made and good quality. It supports 10/100/1000 (1G)/2500 (2.5G) bandwidth, which is great. I got this because although my laptop has a built in ethernet port, for some reason even though it’s not a very old laptop the stated speed of the built in port is only 100 Mbps…much too slow. I got this adapter and plugged it in and tested it, and was thrilled to see my download speed is now just under 500 Mbps, which is the speed I’m supposed to get from my provider. I should also mention that although the specs don’t state that it is compatible with Windows 11, that is what I’m running and it does work for me. I could not be happier with this!

Easy as Plug ân Play
I used this with a Macbook Pro with an M1 Chip on the latest operating system as of May 2024.This was truly as easy as plugging it in and connecting it via an ethernet jack. Mac immediately recognized it and 1 quick âAllow Accessoryâ pop up later I was taking advantage of 2.5Gbps. I was able to transfer documents to my NAS at a blistering 300 MB/s which is almost at the limits of 2.5Gbps so I was extremely happy with the performance of the little dongle.Was pleasantly surprised that after extended use, it did not get hot and easily kept up with tons of file copies and network traffic.Overall if you are looking for a 2.5Gb ethernet adapter this is an easy recommend

Works well and the USB A interface is a great option but it has no link or speed lights
I tested the ULANSeN 2.5G USB3.1 Ethernet adapter on two different computers using the USB A connection. Computer 1 is two years old with an Intel Core i7-11700K processor with USB 3 on the motherboard backplane. Computer 2 is a 16 year old Intel Core 2 Q9400 processor with a PCIe USB 3.0 adapter card using a Renesys chipset. Computer 1 worked as expected. Computer 2 experienced Ethernet disconnects every 2-3 seconds which would last 5-10 seconds and extremely slow speeds (2Mb/sec or worse). I tried newer drivers from Realtek and some buffer adjustments which improved speed but still resulted in some disconnects. Since the adapter worked fine with the newer computer, I will assume there is either a conflict with the Renesys USB chipset or this type of USB Ethernet adapter is not designed for such old hardware. Going back to computer 1, I performed data transmission tests between it and known working interfaces of varying speeds with iPerf3 and compared those same tests against another brand USB C 2.5G adapter. From a raw throughput perspective, the LANSeN product performed nearly identically to the other brand USB C adapter. Overall, the adapter works as expected and does improve throughput beyond a regular 1G Ethernet connection. My only complaint with the LANSeN product is that it has no link or speed lights on the adapter. Every other adapter I have ever used has those lights. When plugged in, I can see a faint blue light emanating from inside the adapter (viewed through the open RJ45 port) but this is not visible when a cable is attached nor would it signify link or speed. I was able to verify both from the management interface of the Ethernet switch to which it was connected and the Windows 10 Network Sharing Center that the adapter was connecting at 2500Gbps. The iPerf3 throughput tests were averaging 1.79-1.82 Gbits/sec when connected at 2500Gbps. When I changed the receiving adapters port speed to 1000Gbps the LANSeN adapter averaged 920-922 Mbits/sec.

Computer says it’s running but games react differently
My Internet connection is fantastic with this device and my games perform amazing but they do show a spike in MS response time but show absolutely no lag! It’s weird how when I play call of duty, it shows the lag spike constant but MS says 0 and gameplay is smooth and consistent.None of that matters as long as the performance is there! And it is!!!

Great tool for a technician
As a computer repair tech, this is a must have in the kit. I love that it’s both USB types and supports the 2.5 gbps speed. With built in drivers it’s so easy to get a client’s laptop, tablet or desktop device connected to download whatever drivers or other tools I may need.It would also serve well as a dedicated network adapter for your computer or device.

Perfect!
This is a great adapter! It is faster than the one I have now at 2.5gbps. It also comes with both USP A and C connectors. It was great to be able to maximize my internet service. The only con is that it doesn’t have a light to tell you if it is linked or speed. I did this through my network, but it would be nice to have a window to actually show what the results were. In a rural area, this was a pleasant surprise. I would recommend.

Funzionale al 90%, non spesso ma si è disconesso dal sistema windwos ,presumibilmente per un bug dei driver che forse si risolverà con un aggiornamento. Impossibile in alcune distro Linux l’installazione dei drivers.
