Linux Bonding Made Easy with Speedify: Unbreakable VPN Connection by Combining Starlink, Wi-Fi, 4G, 5G, and DSL
Want faster upload and download speeds and more reliable internet on Linux? Run two or more connections – such as Starlink, Wi-Fi, 4G/5G cellular or DSL – at the same time. Speedify is an app that combines two or more internet connections at once, so you get faster uploads and downloads and stay online if one connection drops out.
On Linux you can also share the combined connection with your other devices over Wi-Fi or Ethernet.
<1 sec
With Speedify, your internet stays on when one connection fails.
When one of your internet connections drops, Speedify shifts your traffic to your remaining connections in under a second — so calls don’t cut out and downloads don’t stall.
Should you have a backup 4G, 5G, Starlink, or cable internet connection?
Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.
4G/5G cellular
Works anywhere. Just a SIM or hotspot — no installation needed.

Best for fixed locations. Different network, so outages rarely overlap.

What Is Network Bonding?
The network bonding term refers to methods of using multiple Internet connections simultaneously to increase the throughput capacity beyond what a single connection can sustain. Another important benefit is getting a reliable connection. If one of the connections should go bad or disconnect, the overall bonded Internet will stay online thanks to the other connections that are still working.
With Linux network bonding you can theoretically combine any type of connections. If you want to set this up manually, you have to follow some steps:
- Set up bonding driver and options
- Configure each bonding device
- Configure routing
- Troubleshoot any issues
There’s a simpler way to do Linux bonding: using Speedify for Ubuntu and Raspberry Pi OS. Speedify uses established channel bonding technology to combine 2 or more active connections on Ubuntu and Raspberry Pi OS (for Raspberry Pi).
Why Speedify for Linux is the Best Network Bonding Software
Speedify is an established brand when it comes to bonding network connections together on computers and mobile devices with over 1 million active users worldwide. It’s been available for Windows, macOS, Android, and iOS since 2014, and now with version 8, it’s officially available for Linux (Ubuntu and Raspberry Pi OS) as well!
Speedify for Linux runs on Ubuntu and Raspberry Pi OS but is likely compatible with other Debian-based Linux distros. It has both a full user interface, but also a command-line interface. Plus, it’s accompanied by a Python API (available on GitHub) to allow full control and interaction between other programs, scripts and Speedify.
It’s the perfect tool for:
- Anyone doing live streaming (Twitch, YouTube, Facebook Live, etc.), including IRL streamers. You can put Speedify on a tiny Raspberry Pi in your backpack and connect all your cellular connections.
- Anyone looking for a stable and faster Internet for their whole home network. Speedify can be used on Ubuntu and Raspberry Pi OS devices with networking functions to bond and encrypt all your Internet connections, and then share the bonded connection with the rest of your network.
- Anyone with a Linux computer running Ubuntu or Raspberry Pi OS who wants speed and security.
Anyone doing mission critical tasks like live streaming as a reporter, vlogger, online gamer, or doing a business online. Using Linux for your Internet bonding and sharing gives you rock solid reliability for your Internet.

Speedify for Linux: Share the Bonded VPN Connection to Your Other Devices via Wi-Fi or Ethernet
One of the strengths of using a Linux machine (including Raspberry Pi) is its native ability to act as a router. So, Speedify on Linux includes scripts to share the bonded VPN connection over either Ethernet or Wi-Fi.
To configure Speedify as a Hotspot, please follow the instructions in our knowledge base. There’s also a video available on the Speedify YouTube channel.
To configure Speedify as a wired Ethernet router, see the steps you need to take here.
Speedify for Linux: Talk to It from Your Own Program or Script
Speedify 8 also introduces a brand new Python API available on GitHub. This enables you to control Speedify programmatically on Linux.
So, you can do things like:
- Make sure you’re connected, and either connect you, or notify you if there is an issue
- Change settings and priorities based on what you’re doing:
- When you start streaming
- Time of day
- Location, etc.
- Monitor statistics about connectivity (speeds, latency, and loss are available in real time)
- Run speed tests across all connections and record results
