How To Combine Two Ethernet Connections
Setting up your Mac or PC to use multiple Ethernet connections at the same time is a very simple task. In fact, any computer running Windows 7+ or macOS can connect to any combination of available Internet connections. In most cases, setting up multiple Internet connections on your computer doesn't even require any extra hardware.
If you're trying to connect multiple Internet connections for faster speeds, note that your various connections must come from different Internet sources. For example, Wi-Fi and Ethernet networks that are connected to the same router cannot be combined for increased bandwidth using channel bonding applications like Speedify, because they both share the same upstream network.
STEP ONE: CONNECT YOUR FIRST ETHERNET CABLE
Find your PC or Mac's ethernet port and connect the Ethernet cable. If your computer doesn't have a built-in Ethernet port, you can use a low-cost USB-to-Ethernet adapter.
STEP TWO: CONNECT YOUR SECOND ETHERNET CABLE
Since most computers do not have multiple Ethernet ports, use a USB-to-Ethernet adapter to connect your second Ethernet connection.
STEP THREE: COMBINE ETHERNET CONNECTIONS WITH SPEEDIFY
Now that you have both Ethernet links connected to your computer simultaneously, you might want to combine both networks for faster and more reliable Internet. This is where Speedify comes in. Speedify is a cloud service for Mac & PC users that combines all the Internet connections available to your computer to create a single fast super-connection. To get started with Speedify, simply follow this link to download the installer.
Speedify automatically detects the two Ethernet connections and draws them each in a "bubble" near the top. That means you're using both for their combined speed and reliability. At this point, Speedify is bonding your two connections! Browse through the panes at the bottom to see graphs and statistics on how Speedify is using the connections.
