DUB-E250 D-Link USB-C to 2.5Gb Ethernet Adapter

I bought this D-Link USB-C to 2.5Gb Ethernet Adapter in April last year. It cost me $45.43 plus tax.

The full name of this product is Thunderbolt to Ethernet, Compact, 2.5X Faster Than Standard Gigabit, Future-Proof, Windows, Mac, 10/100/1000/2500GB (DUB-E250).

This adapter is USB Type C to Ethernet RJ45. It helps the laptop which has a USB Type-C-only port connect to the ethernet LAN or whatever network.

Ethernet Adapter

I did test the speed with iperf3 a long time before. It meets the standard and is not much hot.

Not too complicated, I just did an iperf3 test. See below.
