⚠️ Important Notice: 2.5Gbps Hardware Requirements & Driver Setup

1. 2.5Gbps Network Chain Required: To achieve maximum 2.5Gbps (2500Mbps) transfer speeds, your router, network switch, NAS, cabling (Cat6/Cat6a or higher), and internet service must all support 2.5GBASE-T standards. Connecting to standard 1Gbps or 100Mbps ports will automatically negotiate at their maximum supported speeds.
2. Operating System & Drivers: Supports plug-and-play operation on modern operating systems including Windows 11/10, macOS, ChromeOS, and iOS 17+. If your operating system (such as Windows 7/8/8.1 or legacy builds) does not automatically recognize the adapter, please download the official Realtek RTL8156BG driver.
3. 2-in-1 Dual Connector: Features a native USB-C connector with an attached tethered USB-A adapter. Simply toggle between ports to connect to both modern USB-C/Thunderbolt and traditional USB-A host devices.

Frequently Asked Questions

Q: Why is my connection speed showing 1Gbps instead of 2.5Gbps?
A: The adapter automatically negotiates speed based on the lowest common denominator in your network chain. If your router, switch, or Ethernet cable only supports 1Gbps, the adapter will operate at 1Gbps. Ensure all network hardware supports 2.5GBASE-T.

Q: Can I use this adapter on a computer that only has traditional USB-A ports?
A: Yes. Simply plug the native USB-C connector into the attached tethered USB-A adapter, and plug the USB-A end into your computer's USB port.

Q: Does this adapter require external power?
A: No. The adapter is fully bus-powered directly through the host USB port and does not require an external power supply.
