USB/RJ45 dongle


I came across this old post and wonder how is it possible for such a USB/RJ45 to deliver a 1Gps bandwidth while the USB2 specs can only max out @480Mbps. It really puzzles me. Anyone?


Hi Mazilo-

Thanks for posting with your question!

In short, you’re right, the gigabit adapter’s performance will max out at USB’s lower bandwidth maximum.

That said, for many customers who have only a 10/100 adapter built into their laptop, or in cases where systems don’t have a built in ethernet port, connecting via a USB ethernet adapter can provide real-world performance gains when compared to using WiFi or slower 10/100 adapters.

If you have USB 3.0 available, our USB3-E1000 can provide real-world performance approaching 1Gb/sec:…

I hope that helps clarify, please let me know of any other questions.

Best wishes-
