How to Set Up Speedify on Ubuntu to Combine Wi-Fi and Ethernet

Set Up Speedify on Ubuntu to Bond Wi-Fi and Ethernet for Faster Internet Upload and Download Speeds

Ubuntu can use more than one internet connection at the same time, but it will not do it on its own. Speedify makes it happen. Speedify combines Wi-Fi, 4G/5G cellular, Ethernet, Starlink and other satellite into one connection on Ubuntu, so a download, upload, or live stream pulls the speed of everything you have plugged in, and stays online if one connection drops.

Speedify’s channel bonding technology uses up to 95% of the combined capacity across your connections, with encryption on every one. Speedify supports Ubuntu, Debian, and Raspberry Pi OS on 32-bit or 64-bit ARM and on 64-bit Intel and AMD machines, which covers most laptops, desktops, and servers.

Quick answer

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.

Speedify bonds any two connections into one — automatic failover, more speed, no dropped calls.

Speedify Feature · Pair & Share

Speedify Pair & Share: share cellular between your devices, both ways

Most hotspots give. Speedify's Pair & Share gives and takes. Two devices running Speedify pair up and each uses the other's cellular connection simultaneously, so you both get faster uploads, faster downloads, and a steadier connection. No extra hardware, no new data plans, no setup beyond a tap.

How to Install Speedify on Ubuntu

  1. Open a terminal and run the install command. Speedify provides a single terminal command that downloads and installs the correct build for your system. On a desktop Ubuntu machine this includes the Speedify user interface; on every system it includes the command-line interface. Use the current command from Speedify’s Linux installation guide.
  2. Let the background service start. Speedify runs as a background service after installation, so it is ready as soon as the install finishes.
  3. Sign in. On a desktop, open the Speedify user interface and sign in. On a headless machine, sign in from the command line. Either way, encryption is on by default.

For the full picture of how Speedify works on the platform, see Speedify’s Linux overview.

How to Bond Wi-Fi and Ethernet on Ubuntu

The whole point is using connections together. Plug in the connections you want Speedify to combine, then let Speedify bond them.

For a deeper look at sharing and bonding on the platform, see Speedify’s guide to Linux network bonding and sharing internet over Wi-Fi or Ethernet.

UI or Command Line, Your Choice

On a desktop Ubuntu install you get the same Speedify interface available on Windows and macOS. You also always get the Speedify command-line interface, which can do everything the interface can from a terminal. If you would rather run Speedify with no desktop at all, that headless setup has its own guide.

Why Bond Connections on Ubuntu

A single connection is a single point of failure and a single speed ceiling. Speedify removes both. Two mediocre connections add up to one fast link, a dropped connection no longer drops your session, and real-time traffic like video calls and live streams gets priority. Combining links this way is a long-standing networking technique known as channel bonding. Speedify also doubles as a no-log VPN, so all of that traffic is encrypted on the way out.
