UGREENUSB to Ethernet Adapter 2.5Gb, Ethernet Adapter, Aluminum, USB 3.0 to RJ45 Computer Network Internet LAN Dongle for Laptop, Compatible for MacBook Air/Pro, XPS, Windows, macOS

I noticed that the USB "3" interface is black and NOT USB 3 Blue. I ordered a 2.5 gb switch that will be here on Thursday so I can test properly, but it does look like usb 2 which leaves throughput at 484mbps. Can't get any more than that out of a USB 2. I will try contacting customer su[port and see what their take is***** EDIT*** I loaded a USB utility and DESPITE the fact that the interface is black and does not say SS, it is indeed a USB 3.2 Gen 1 (5 Gbit/s). Great news as I dumped a LOT of money in their 4 bay pro NAS

The ethernet port on my laptop quit working. Rather than try to replace which sometimes can be difficult and not cheap, I elected to give this a shot.This thing worked perfectly. Connects to a USB port, ethernet connects to this device and Im getting speeds right 2.5gbps. (disclaimer, your internet access needs to be fast enough to support this speed, it wont magically make your connections faster).Very easy to use, plug and play, no software or alterations to your computer required. Highyl recommend.

I recently upgraded to 2 gig fiber from Frontier. The network adapter in my desktop was only 1 gig. This thing worked fantastic, and I’m getting full speed from my provider!

Works well with my 2gig fiber getting 2.3 gigs up and down. So far I haven’t noticed any latency issues with this device.

UGreen is not at fault here - USB NICs faster than 1Gbps are just not pleasant to use, especially with 10Gbps switches. There’s not full support for most of the ethtool operations, because USB NICs are almost all controlled by CDC driversJust try to use a PCI card if you can…

Works well - Stable, Plug and Play, and great performance

This worked great in my Synology diskstation ds918+. I was worried about it overheating and dropping out or slowing down, as a lot of dongles do. This one didn't. I ran Blackmagic Disk Speed test for 30 minutes, maxing out the 2.5GB link, and never had any issues. The temperature of the dongle never got above 96 degrees F (or 36C). Don't buy the older dongles with the RTL8156B chip. Get this one (with the updated RTL8156BG) instead!

Worked out of the box on my m4 macbook pro, so it likely works with any modern mac.It reaches the advertised 2.5GBe no problem and has been a nice upgrade to the ethernet I had in my dock.Would recommend/buy again if I happen to need another one.
