Same for your transfer speeds - what you’re seeing is well below USB 2 throughput. USB speeds and feeds have nothing to do with this. In your example, the variance in your ping results - 12ms vs 24ms could be due to the quality of your adapter and/or inherent latency of your internet connection. High quality USB to Ethernet adapters will have low latency (ping results) and higher throughput (iPerf3 results). It’s free snd simple to use.Īs for differences in performance, it comes down to the quality of the USB bridge in the adapter and the quality of the Ethernet chip itself they’re not all created equal. You need to use the iPerf3 utility to measure the performance internally. Your question is very similar to this one: What dowload speeds is the Apple USB Ethernet Adapter capable of? You need to do this internally where you control the variables. If you have issues mixing this adapter with such devices, connect it directly to another Thunderbolt port on your computer, or connect it to a low-bandwidth device on the Thunderbolt chain.You can’t evaluate adapter performance by measuring Internet latency and throughput because those things change - like the Network congestion and load of your service provider at that tine.

Mass Storage and other high-bandwidth devices can affect the performance of this adapter. If you are connecting multiple devices (“daisy chaining”), at least one computer on the Thunderbolt chain needs to act as a host.Ĭan other devices on the Thunderbolt chain affect the performance of this adapter? You can also connect it to external devices like Apple Thunderbolt Displays or other devices that have multiple Thunderbolt ports.Īre there other requirements for using the adapter ? Thunderbolt-equipped Macs released prior to June, 2012, require the installation of Thunderbolt Software Update 1.2.1 to use this adapter.Ĭonnect it directly to the Thunderbolt port on your Mac. This adapter requires OS X Lion v10.7.4 or later. Which computers support the Apple Thunderbolt to Gigabit Ethernet Adapter?Īll Thunderbolt-equipped Mac computers support this adapter.
