Plugable 2.5Gbps usb ethernet adapter review | MacSources

Upgrade your connection by adding this 2.5 Gigabit Ethernet adapter to any system

When I made the switch to using a newer model MacBook Pro, I knew I was sacrificing i/o options for power and other modern upgrades. I have a 2016 13-inch MacBook Pro, which only has USB-C/Thunderbolt 3 input/output ports. Therefore, I am somewhat limited when it comes to activities that involve a straight Ethernet connection. Fortunately, Plugable, one of my new favorite accessory companies, has designed a USB-C Ethernet Adapter specifically for this use case.


The Plugable 2.5Gbps USB Ethernet Adapter makes it possible for USB-C computer to connect directly to Ethernet without a larger docking solution. This adapter has been tested to be faster than a traditional Gigabit Ethernet connection and is compatible with both USB-C and USB-A connections thanks to the included attached USB-A adapter. The 2.5 Gigabit Ethernet signals that the Plugable adapter provides are designed to work with existing Category 5e cabling. The adapter is compatible with all modern operating systems including Windows (10, 8.X, and 7), macOS (10.7+), and Linux (Kernal 3.2+).

  • USB Connection: USB Type-C or USB Type-A with attached adapter
  • Transfer Rates: 100BASE-TX, 1000BASE-T, and 2.5GBASE-T (IEEE 802.3bz) with Auto-Negation
  • Supported OS: Windows 10, 8.x, and 7; macOS 10.7 and above; Linux Kernel 3.2 and above
  • 1x USB-C to Host: SuperSpeed USB 5Gbps
  • 1x USB-C to USB-A Adapter: SuperSpeed USB 5Gbps
  • 1x Ethernet (8P8C) Port: NBASE-T 100/1000/2500 requires CAT 5e and 2.5GBASE-T network equipment for full performance. Reduced performance with half-duplex
  • Additional Features: 9k Jumbo Frame Support, Auto MDI-X (Crossover Detection and Correction), and IEEE 802.1Q VLAN support (Depending on OS), and Power/Activity LEDs


The adapter came boxed in a standard retail package. Plugable’s brand colors include white and green and so the box features green as an accent color. There is a photo of the adapter on the front that clearly shows the attached USB-A adapter that makes this device universally compatible with modern USB connections. The back of the box provides specs and details about the product including the model number. Once you open the box, you’ll find the adapter and a quick start guide. That’s all that’s in the box. While it’s a very nice box, I do think that the packaging could be reduced a bit given the compact size of the device.

  1. The drivers for the adapter have not installed properly or are corrupted.
  2. The Ethernet Cable plugged in is not live or is faulty.
  3. The adapter has failed.


While most of the world turns to wireless connections as the answer to the Internet, it’s not the only answer. A good wired connection comes in handy when you really need a dependable signal. The Plugable 2.5Gbps USB Ethernet Adapter provides an impressive, fast connection that is hard to beat. The device I compact, lightweight and easy to carry around. It will definitely make its way into my standard laptop kit for those times when I have to connect through Ethernet.
