Better Internet, Anywhere & Anytime!
Want faster upload and download speeds and more reliable internet, wherever you are? Run two or more internet connections, such as Wi-Fi, 4G/5G cellular, Ethernet or Starlink, at the same time. Speedify is an app that combines them into one connection: it splits your traffic across all of them, and if one connection drops out, the others keep you online.
This guide shows where to find a secondary internet connection at home, at work or on the road, so you always have at least two to combine. Speedify’s speed and failover gains need two or more connections; on a single connection it works as an encrypted VPN and cannot make that connection faster. A simple start is Wi-Fi plus your phone’s 4G/5G cellular: see how to combine Wi-Fi and 4G/5G on a computer.

Combine Every Internet Connection You Find with Speedify
As the table shows, there are internet connections almost everywhere if you know where to look. With Speedify, you can use them all at the same time.
Two broadband lines at home work the same way. Connect the computer to one router with an Ethernet cable and to the other router’s Wi-Fi network, and Speedify uses both lines at once; each line keeps its own modem and router, so no extra networking hardware is needed.
