Overview
The UGREEN 25052 (CM648) adds a wired 2.5 Gbps network port to a laptop, tablet or iPhone that has a USB-C data port. It suits anyone who moves large files to a 2.5G capable NAS or switch, or who wants a steadier link than Wi-Fi at a desk. When the equipment at the other end is slower, the port drops to 1 Gbps, 100 Mbps or 10 Mbps on its own.
Is it right for you?
- Suits a USB-C laptop, tablet or iPhone on a network that already has 2.5G ports on the router, switch or NAS.
- Still useful on an ordinary Gigabit network, where it links at 1 Gbps, but it cannot make Gigabit-only equipment run at 2.5 Gbps.
- The USB-C port must carry data; a charge-only port will not work.
- Not a Wi-Fi adapter, router, modem or switch, and it does not supply Power over Ethernet (PoE).
Key features
- Realtek RTL8156BG controller with 10, 100, 1000 and 2500 Mbps link modes and auto-negotiation.
- Aluminium housing and a reinforced cable, 60 g in the hand.
- Two network status LEDs show link and activity at a glance.
- Driver packages for Windows, macOS and Linux (version dependent), and support for iOS and iPadOS.
- Network only: no PoE, no charging pass-through and no video output.
What else you need
A host with a USB-C data port, an Ethernet cable and a router, switch or NAS port. For a predictable 2.5 Gbps link use a known-good four-pair Cat6 cable and a 2.5G port at the other end.
Installation
Plug the adapter into the USB-C port and connect the Ethernet cable. Driver packages exist for Windows, macOS and Linux; which one applies depends on the operating system version, so install one only if the connection does not appear on its own.
Before you buy
- A link that negotiates at 2.5 Gbps does not guarantee 2.5 Gbps in a file transfer; the rest of the network path sets the real speed.
- Retail bundles can vary. Ethernet cables, routers, chargers and host adapters are not in the box.
