Speed Specifications:
●USB3.2 Gen 1: Theoretical maximum bandwidth 5 Gbps.
●USB3.2 Gen 2x1: Theoretical maximum bandwidth 10 Gbps. The computer may detect it as 10 Gbps, but actual tested speed is around 7 Gbps.
●USB3.2 Gen 2x2: Theoretical maximum bandwidth 20 Gbps. The computer may detect it as 10 Gbps, but actual tested speed is around 9 Gbps.
(For optimal performance, it is recommended to use a USB3.2 Gen 2x2 port).
Regarding Thunderbolt Ports:
●Thunderbolt ports are compatible with the USB protocol. Therefore, this network adapter can be used with Thunderbolt 3/4/5 interfaces.
About MAC Devices Not Recognizing 10G:
●Due to system reasons, when connected via a Thunderbolt port, MAC devices may only detect and display the connection as 5 Gbps. However, actual speed tests can exceed 5 Gbps.
About Drivers:
●Currently, only genuine Windows 10 or Windows 11 systems with automatic updates enabled in the background will automatically download and update the network adapter driver online.
●Pirated/counterfeit systems cannot receive automatic updates and therefore will not automatically download the latest network adapter driver.
●If the device is not recognized or is recognized as 100 Mbps after connection, please go to the Realtek official website to download and install the driver.

Devices with Thunderbolt 4 chips, specifically the 8-series and above, can achieve speeds of up to 9.6 Gbps when this network card is plugged in and recognized as USB 3.2 Gen 2x2.
(Tested device: Intel Ultra 7 255H, with a front-end retimer chip from the 8040 series, recognized as a Gen 2x2 20G port.)
【Flagship Chip】
Equipped with the Realtek RTL8159 professional chip, it ensures stable performance during sustained high-intensity data transmission. With a typical power consumption of just 1.95W, it balances high performance with low energy consumption.
【Tested Speeds】
Please note your device's interface:
Connecting to USB 3.2 Gen1 (5G bandwidth) cannot achieve 10G speeds.
USB 3.2 Gen2x1 (10G bandwidth) achieves approximately 7G in tests.
USB 3.2 Gen2x2 (20G bandwidth) achieves approximately 9.6G in tests.
It is recommended to use a USB 3.2 Gen2x2 interface for the best experience.
On macOS, due to driver limitations, the interface may only display 5G, but the actual transfer speed is higher than 5G. Realtek is urgently working on driver updates. If this concerns you, consider purchasing after the driver update.
【Alloy Body】
The thickened aluminum alloy shell, combined with built-in metal fins, ensures efficient heat dissipation, maintaining high-speed performance even during prolonged use. The compact dimensions of 99*42*22mm make it highly portable.
【Customer Support】
Widely compatible with Windows, Linux, macOS, and Thunderbolt 3/4/5 interfaces. Windows 10/11 systems can enable automatic driver updates for a plug-and-play experience. If your device's speed is abnormal, manually download the driver from the Realtek official website. (For any questions, leave a message for customer support, and we will respond within 24 hours.)
Q1: What type of USB interface is required to achieve 10G speeds?
