Used this adapter on a few computersIts based on realtek RTL8157 chip , so if you have a speed related issue, slower dowload or upload speed, disconnecting issue , go to your device manager / network adapters, look for a " realtek USB adapter " or something simillar and check the driver date if its says 2015 and not 2026, your pc deffinietly need a new driver for this adapter to work.Its impossible to find a driver base of the model number on the ugreen website : " ugreen cm848 " instead use google search for a "Realtek RTL8157" driver, as this adapter is built on that realtek chip. That driver mostly can fix all your issues :)Overall the product is working fine, no mayor issues, using it in the past 10 months

UGREEN has been putting out some real high quality items these days, and this adapter falls right in line. It works exactly as you'd expect it to. I've got it connected to a MacBook Air M4 and it's been functioning as good as I could imagine. No issues with the computer recognizing it and data speeds are definitely faster than WiFi. Quality appears to be pretty solid and while it can get a little warm, it's nothing I would be concerned with. Recommended.

Don’t do it!!! Go to all reviews and click on 1 star and read the comments. Most people don’t have a clue what they are doing… I see reviews comparing it to WiFi others super happy with 2200mbps speeds!!! It’s a “5000mbps” dongle!!! I own another one from another company! You can get these speeds with other brands. This thing is garbage. I bought it because I have a full 5G network and one of my 2.5G USB adapters failed so instead of buying another 2.5G I figured I’d add one more 5G adapter. Even talking to a computer that’s plugged into the network with a 25G fiber connection this thing doesn’t do consistent 1G/1G connections. I have 1gbit, 2.5gbit, 5gbit and 10gbit ports… it doesn’t work great with any of them. The only time it works decently is on a USB 4.0 full bandwidth port on one of my laptops and I still can’t get 5gbit with it!!! Also it’s not stable. I read it might work well with MAC so I’ll try it on my brother Mac Mini M3 and if it works well I’ll give it to him.Garbage

This UGREEN USB-C to Ethernet adapter works perfectly! It was truly plug-and-play — my laptop recognized it instantly with no drivers needed. The speed is fantastic; I’m getting full 5Gb performance with rock-solid stability. The build quality feels premium, and the compact design makes it easy to carry in my laptop bag. It’s a great upgrade for anyone who needs a fast, wired internet connection on a USB-C device. Highly recommend this adapter for both home and office use!

Needed a way to connect my laptop to the network. This gives me 5 times faster data transfer over my local network vs wifi. If you need to go the wired route, this is a good cost effective option. It has an aluminum body for head dissipation and is sleak to look at. Would buy again if needed, but I don't think I will ever need to. It will last for years to come.

Mostly works great once you load the drivers (make sure you download them from Ugreen). Otherwise you might not get full link speed. I also find that it doesn't always work on boot but if I disconnect it and reconnect it, everything is fine. It probably has a power saving bug or something but it is a minor issue in my use case.

Ottimo adattatore fedele alla descrizione e con ottime prestazioni. Tutte le porte funzionano perfettamente.

L'adaptateur a été reconnu nativement et immédiatement par MacOS, les débits que j'ai obtenu sont tout a fait conforme (plus de 4gbps), il est relativement compact et ne chauffe pas.

Works as intended on both Linux and Windows hosts. Note that the realistic throughput would depend on what USB port can deliver and what the network and do. Uploading terabytes of data from my older Thinkpads at 350 MB/sec (2.8 Gbps) without a hitch. Up/down iperf3 throughput with modern Thinkpad was 4.6/3.8 Gbps easily. Gets a bit hot under heavy use.

eindelijk een produkt dat zijn beloftes waar maakt, PRIMA

I tested this adapter with iperf3 and the real throughput is around 4.73 Gbps, which is very good for a USB 5Gb adapter. The performance itself is solid.However, there is no driver included in the package, and there is also no driver available on the UGREEN website. I had to search for the driver manually through Google, which was inconvenient and shouldn’t be necessary for a new product.Because of the missing driver support, I would take off half a star.
