Improve Bandwidth and Latency by Combining Two Starlink Connections on Linux
Combining two Internet connections may seem like rocket science, but it’s actually quite simple if you have the right channel bonding app like Speedify.
In this guide we’ll show you how you can use your Starlink satellite Internet connection via Wi-Fi together with another Starlink connection via wired Ethernet and then use Speedify to combine them.
Speedify bonds your Starlink with another Starlink, 4G/5G cellular, cable, DSL and splits traffic across them. If Starlink drops mid-call or mid-transfer, Speedify fails over to your remaining connections instantly.
NOTE: For best results, use internet connections from different sources. Joining one router over both Ethernet and Wi-Fi won't help.
Most Starlink users already run a second connection.
From a sample of 6,228 Starlink users on Speedify, 71% ran at least one other internet connection while using Starlink. Cellular is the most common choice of backup connection.
What they pair with
Should you get a backup connection for Starlink?
Yes. Starlink goes down every day — an always-on dish averages about 34 minutes of downtime daily from routine satellite handoffs. A second connection keeps you online when Starlink drops.
What’s the best backup connection for Starlink?
A 4G/5G cellular hotspot or SIM is the most practical backup for most Starlink users — it works anywhere Starlink works, requires no installation, and uses a different network so outages rarely overlap. Cable or DSL broadband is a strong option if you have it at a fixed location. A second Starlink dish is also possible if you need maximum throughput.
How do you use two internet connections at once with Starlink?
Speedify combines Starlink with any other connection — cellular, cable, Wi-Fi, or a second dish — into one bonded connection. Speedify runs on your phone, laptop, or router. When Starlink drops, Speedify moves your traffic to the backup instantly, so calls don’t cut out and downloads don’t stall. Speedify is free to try.
71% of Speedify’s Starlink users already run a second connection. Speedify’s Starlink Index tracks real-world Starlink performance data from thousands of dishes.

Research confirms Starlink switches between satellites every 15 seconds on a fixed schedule. Each satellite handoff is a potential dropout, and on a congested network or with any obstruction, those Starlink dropouts become real interruptions.
Speedify fixes Starlink connection drops by combining your Starlink internet connection with another satellite dish, Wi-Fi, 4G/5G cellular, or wired Ethernet at the same time. When Starlink drops, Speedify keeps your traffic moving on the backup internet connection instantly.
Speedify alerts you about your Starlink dish status
Speedify software alerts you about your Starlink dish status as soon as your dish experiences an issue - e.g. when your actuator motor is stuck, the mast is not vertical or there's a thermal throttle.
Speedify's Starlink Control Center helps you monitor all your Starlink dishes, read obstruction maps, and align multiple dishes all in the Speedify app. Get a real-time view of each dish's health and optimize the position of each Starlink dish, so you get the best possible performance out of your Starlink connections.
3 Steps to Combine Two Starlink Connections on Linux Using Speedify
Step 1: Connect to Your First Starlink’s Wi-Fi Hotspot
First - make sure you setup your Starlink according to the instructions you received in the package. This includes setting up your new Starlink Wi-Fi network, along with your password.
Click on the arrow in the top right corner (also known as the System Menu) then Wi-Fi > Select Network and choose your desired network. Select the Wi-Fi hotspot associated with your Starlink connection and enter the password to connect.
Step 2: Connect Your Second Starlink via Ethernet Cable to Linux
To connect your Starlink via Ethernet to Ubuntu, use an Ethernet cable between your Starlink router and the Ethernet port on your Ubuntu computer. If your computer doesn’t have a built-in Ethernet port, try using a USB to Ethernet adapter instead. Ubuntu will start using your Ethernet connection and you should see it listed in the System Menu under “Wired Connection”.
Step 3: Download and Install Speedify
Last but certainly not least, download and install Speedify. Once running, Speedify will automatically detect your two Starlink connections and combine them for increased speed, security, and stability.
Need to keep several devices connected in areas with limited or spotty network coverage, like event venues, remote locations or when traveling? Get consistent and uninterrupted online activity for all your devices using Speedify's Pair & Share functionality, which allows you to share cellular data between multiple devices wirelessly.
By pairing devices, you can effectively distribute your cellular connection across them, improving overall performance, especially when other network options like Wi-Fi may be slow or unstable.
You can manage settings, view statistics, and even apply limits to individual connections by either clicking/tapping on them from the Dashboard or by navigating to the desired connection through the main Settings menu.
Speedify will work quietly in the background to optimize performance including prioritizing streaming web traffic to avoid stuttering, buffering and disconnects.
When using Starlink Internet, Speedify is the only VPN that makes your online experiences faster, more reliable, and more secure.
