How channel bonding works

Most PCs use one connection at a time. If Wi-Fi drops or slows down, your call or stream suffers, even if a phone with mobile data lies on the desk. Speedify uses all available connections together: Wi-Fi, Ethernet, a USB-tethered phone or a second Wi-Fi adapter. It splits traffic across them through its own servers and puts it back together, so the bandwidth adds up and, more importantly, a failing link does not interrupt the session. For live streaming, video calls from trains or cafés, and work from places with unreliable internet, that redundancy is the main selling point. Because traffic passes through Speedify's servers, it is also encrypted like a VPN. The trade-off is that every connection you add may consume data, which matters with mobile plans, and your traffic depends on the provider's servers. Version 17 is described in the Speedify 17 release notes.

System requirements

According to the official download page, Speedify needs Windows 10 or later, macOS 11.5 or later or Android 9.0 or later, and it is available for Ubuntu, Debian, Raspberry Pi OS and other Debian-based Linux distributions.

How to install it

1. Download the installer from the Speedify download page.
2. Run setup and allow the network adapter it installs.
3. Connect your extra link, for example a phone via USB tethering.
4. Start Speedify and check that both connections appear as active.

Getting the most from it

Bonding works best with connections that do not share the same weak point: a fixed line plus mobile data is better than two Wi-Fi networks from the same router. Set the mobile link as a backup in the settings if you only want it used when the main line fails; that keeps data costs down. For streaming, run a short test broadcast first to see how the combined link behaves.

Price

Every month, 2 GB of Speedify data are free; paid plans offer unlimited usage.

Safety and privacy

Download only from speedify.com. Like any VPN, the service can technically see the traffic that passes through it, so read its privacy policy. Watch mobile data usage if you bond a phone connection.
