Want faster upload and download speeds and internet that stays online even if one connection drops out? Run Ethernet and a tethered phone at the same time.
Speedify is an app that combines two or more internet connections at once – such as Ethernet and a tethered iPhone or Android’s 4G/5G – 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 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: Tether Your Smartphone
Refer to your carrier or smarthphone’s instructions to tether your smartphone’s mobile Internet to your computer. Here is a handy guide for tethering on most of the popular mobile broadband networks in the US.
Step 3: Combine Ethernet and Your Tethered Phone with Speedify
Now that you have both Ethernet and your phone’s tethered mobile broadband network connected to your computer simultaneously, you might want to combine both 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 download and instal the application and you’re ready to go. Once Speedify is running, you’ll see both Ethernet and tethered phone connections detected. That means you’re using both for their combined speed and reliability.
