UGREEN USB to Ethernet Adapter 2.5Gbps | 25051
The UGREEN CM648 (item 25051) adds a 2.5Gbps wired network port to a computer through its USB-A port. It connects over USB-A 3.2 Gen 1 (5Gbps), uses a Realtek RTL8156BG chip and has an aluminium housing with LED indicators.

2.5Gbps wired network: The RJ45 port runs at up to 2.5Gbps, which is 2.5 times the speed of a normal Gigabit port. It also works on 10/100/1000Mbps networks, so you can use it today on a Gigabit network and get the higher speed later.

Realtek RTL8156BG chip: The adapter is built on the Realtek RTL8156BG 2.5G Ethernet controller. Realtek drivers for this chip are available for Windows, macOS and Linux.
Aluminium housing with LED indicators: The aluminium case helps the adapter release heat during long transfers. Two LED indicators on the port show the link signal and the connection status at a glance.

Who it's for / Works with
Laptops and desktop PCs with a USB-A port running Windows, macOS or Linux (Linux with standard kernels; UGREEN lists kernel 5.17 and later). It is useful for connecting to a NAS, a 2.5G router or a 2.5G switch.

Good to know
To get 2.5Gbps, your router, switch or NAS must also support 2.5G Ethernet; on a Gigabit network it runs at 1Gbps. Some systems need the Realtek driver to reach the full 2.5Gbps speed. UGREEN states that it is not compatible with Nintendo Switch, Wii or TVs.
