MetroPCS 4G LTE Speed Test Logs (Nov 26 ~ Dec 18, 2013, Austin, TX)

USB2.0 to Fast Ethernet (VK-RD9700) Quick Test

Figure 0. USB2.0 to Fast Ethernet Adapter, RD9700 Chipset.

The performance of the USB2.0 to Fast Ethernet is quite disappointing.

Figure 1. USB2.0 to Fast Ethernet



The Figure 1. shows the speed test result from www.speedtest.net using the USB2.0 to Fast Ethernet adapter. The maximum download and upload speed is about 6.5 Mbps. This is not due to the maximum capacity of the internet connection I use. As a control, I performed the same test through the same LAN port but with the built-in gigabit ethernet port in my laptop. The result is shown in Figure 2.

Figure 2. Built-in gigabit ethernet port

As seen, the speed provided by my ISP is much higher than 6.5 Mbps up and down. Hence, the extremely slow speed stems from the USB2.0 to Fast Ethernet adapter.

The theoretical data transfer rate of USB 2.0 is 480 Mbps. Assuming it can use only the half of it in practice, the adapter should provide the full speed of Fast Ethernet (100 Mbps). Thus, the test result is quite disappointing.
