Our top equipment picks
Because the Surface Book 2 and Surface Book 3 don't have an Ethernet port, you have to use a dock or dongle that allows you to connect an Ethernet cable to the device using the Surface connect port, USB-A port, or USB-C port.
USB-C heaven
The Surface Dock 2 brings much-needed updates to the original, adding in four USB-C ports alongside the usual Ethernet, USB-A, and 3.5mm jacks.
This new and improved Surface Dock has new ports, faster speeds, and provides more power to your supported Surface devices. You'll have to wait a bit to order this new dock, though, since it was just announced and isn't available quite yet.
Helping it to feel like a desktop
In addition to adding an Ethernet port, the Surface Dock has four additional USB ports, two additional mini-display ports, and a 3.5mm audio jack.
The older Surface Dock is outdone by its successor in just about every way, but if you have an older Surface device and want to use a Surface Dock, you have to go with the original.
Modern connectivity
This tiny dongle can easily fit in a bag. It works through USB-C, which is becoming more common on devices.
You can use this dongle with your Surface Book 2 or 3's USB-C ports. It supports USB 3.1 and can transfer files with 10/100/1,000 Mbps network speeds.
More compact and budget-friendly option
This adapter is easy to fit in your bag and adds an Ethernet port to your Surface Book 2.
While this dongle doesn't have as many ports as the Surface Docks, it has a dedicated Ethernet port that handles 10/100/1000mbps networks and is smaller and less expensive than either Surface Dock.
Additional Equipment
You can't have Ethernet without a cable, and a Cat-6 cable will handle just about any internet speed you throw at it.
Amazon Basics Cat-6 Ethernet cable (opens in new tab) ($7 at Amazon)
This cable can transfer up to 1Gbps more than most internet connections.
