USB C to Ethernet Adapter 5Gbps, Ethernet Adapter for Laptop

This ethernet adapter works very fast. The instructions maybe could be better as I didnt find th drive on their official web site, but with the code mencioned on the instructions I found it on another page for mac, windows and linux. Goes extremely fast, but you must know if your PC connections can achieve that speed (5Gbps), and also if your hard drive goes that speed (I have a NVME drive and USB-c thunderbolt on the pc (40Gbps). When I tried on the usb 3.0 or the USB 2.0 with an adapter for usb-c to normal usb the speed was not the expected and way slower on the usb 2.0. So, if there are no bottle necks in your PC it will work very well. I’m also using it to connect a windows PC to an imac 2020 as external display with Luna display wired option (I bought two of these devices and connected the thunderbolt 4 of the PC to the thunderbolt 3 of the imac with a cat 8 ethernet cable) and it goes very well (1ms latency and had maximum speed). Thank you Ugreen for your hard work.

I’ve been really impressed with this 5GbE adapter from UGREEN. It delivers consistently fast speeds, works flawlessly with my setup, and feels solidly made. For the price, it’s fantastic value—especially if you’re upgrading from 1GbE and don’t want to jump to the cost of full 10GbE gear. Just plug it in to a spare USB-C port and... that's it. Only wish they made a 10GbE version, but for most use cases, this hits the sweet spot. Highly recommended.

UGREEN product. Works like an absolute charm. Nothing more to say

These are brill I buy them all the time and they are sturdy and provided high speed quick access

This is a nicely made item, with a sturdy aluminum metal case (to help dissipate the heat from the 5G adapter chip) and a good quality (braided) USB-C cable which should last a long time. HOWEVER, contrary to the item listing, the item DOES require a driver. The supplied instructions provide an official UGREEN url to download this from. You need to search for UGREEN product "CM848" (in capitals - it doesn't recognize "cm848"). And the only driver currently (March 2026) there is for Windows 11. :-( After a bit of investigation I found that this UGREEN adapter uses the Realtek 8157 chip, and (on Realtek's own driver download page) there are versions of the correct driver for Windows XP, Vista, 7, 8, 8.1 and 10. Also Linux (up to kernel 6.17) and MAC OS 10.8-10.15. (Amazon don't like links included in reviews, so you'll have to find this page yourself) I've only downloaded and installed the Windows 10 driver myself, so I can only confirm that one actually works OK. However, as all these drivers are produced by the 8157 chip's manufacturer, there's no reason to suspect the other drivers won't work too. Quite why UGREEN have failed to included all these other drivers on their own driver download page is a mystery. One other thing to note: the Realtek 8157 chip supports MDI/MDI-X: which means you can directly connect this network adapter to another using a normal ethernet cable (without using a hub, switch or cross-over cable). Assuming you know how to configure the network connection, this provides a very fast way to link two devices directly together.

Regularly get almost 5gbs out of this adapter but it can glitch and disconnect

work 100%

It's a good product, I'm getting the same speed I get on my desktop PC (the full 5Gbps) but it's waaay better than the Wi-Fi. The product has a great quality, very well built. It could be some type of settings, so nothing to do with the seller. It's a fair price, would super recommend it.

Superlativo ed economico. Provato su vari PC e funziona benissimo. Considerando quanto costano gli adattatori USB-C (thunderbolt) a 10Gbps, e considerando che questo va bene su qualunque porta usb-c a 10Gbps, è un affarone Ovviamente lo switch è un multiswitch che arriva a 10Gbps, altrimenti non sarebbe possibile sfruttare l'adattatore.

Funkar på min synology-nas, har inte kunnat prova full hastighet ännu.

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

The product quality is great and I am getting the max capped speed from my ISP, highly recommended
