Gigabyte Ethernet ports have begun vanishing from notebooks nowadays. None of Apple’s current generation MacBooks comes with it. The RJ45 port is too big and takes a lot of space in the notebook which manufacturer don’t line. Sure you can use wifi with almost any modern gadget out there but there are some times when you need a dedicated connection or just need more speed. What we have today fixes that without making a hole in the pocket.

Design and Build

QuantumZero QZAD02 Box

The body is made out of hard plastic casing with a glossy finish on the front along with some branding. The QZAD02 comes with an RJ 45 port on one side and a USB 3.0 Type A on the other. It can be used with speed up to 5 Gbps on a LAN. The cable on the QZAD02 is thick and well built, it doesn’t feel like that it would break pretty easily.

There is an indicator LED on the Top under the plastic which lights up depending upon the scenario.

I was using the Quantum Zero QZAD02 with a Macbook pro, at first, it did not work out of the box. But once the drivers from ASIX website were downloaded then it worked flawlessly after a quick reboot. You can plug the ethernet cable on one end and get the internet working with the QZAD02 instantly.

Overall it’s a great alternative for the Apple branded Ethernet Adapter. It works great even with MAC and the ASIX website has drivers for almost every operating system. Overall it’s a well-built hardware from Quantum Zero.
