Want faster upload and download speeds and internet that stays online even if one line drops out? Run two Ethernet connections at the same time.
Speedify is an app that combines two or more internet connections at once – such as two Ethernet lines from different sources – so you get faster uploads and downloads and stay online if one connection drops out. It works on Windows and macOS.
With Speedify, your internet stays on when one connection fails.
When one of your connections drops, Speedify automatically routes your traffic to your remaining connections — so calls don't cut out and downloads don't stall.
How do I use WiFi and 4G/5G cellular at the same time with Speedify?
Pick your two internet connections and your device below and we'll take you to the step-by-step setup guide.
Step 1: 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 2: 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 3: 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, simply download Speedify here. Then, log into your Speedify trial using the email and password combination we emailed to you, and once Speedify is running, you’ll see both Ethernet connections detected. That means you’re using both for their combined speed and reliability.
