Linux: Use a Secondary Cable / DSL Wi-Fi Connection Together with Your Starlink Ethernet Link
Starlink works on Linux like any other network. Connect your Linux computer to the Starlink router’s Wi-Fi, or plug it into the Starlink router with an Ethernet cable, and Ubuntu picks up the Starlink internet connection with no drivers or extra software. There’s no Starlink app for Linux, but you can check your Starlink dish at dishy.starlink.com or 192.168.100.1 in a web browser.
To use Starlink and your cable or DSL internet at the same time, add Speedify, an app that uses all of your internet connections together. You get the speed of both, and if one drops, Speedify switches your traffic to the other automatically. Speedify needs both lines connected for that: with Starlink alone, it works as an encrypted VPN and cannot stop Starlink from dropping. Below: the three steps on Ubuntu Linux.
Starlink Internet Connection Dropouts Happen to Everyone
Speedify measures thousands of Starlink users in more than 150 countries. From 29 September to 12 October 2026, fixed Starlink dishes went offline for about 37 minutes a day on average, and Starlink dishes on RVs and boats for about 61 minutes a day.
Starlink also switches each dish to a new satellite every 15 seconds, and a switch can cause a short dropout. Even a perfectly installed Starlink dish goes offline, and about 7 in 10 Starlink users on Speedify use Starlink together with a second internet connection, like 4G/5G cellular.
3 Steps to Use Starlink and Cable or DSL Internet at the Same Time on Ubuntu Linux
You need an Ethernet cable (and a USB to Ethernet adapter if your computer has no Ethernet port), the name and password of your cable or DSL Wi-Fi network, and Speedify for Linux.
Step 1: Connect Your Linux Computer to the Starlink Router with an Ethernet Cable
Yes, you can use an Ethernet cable with Starlink. The Starlink Gen 3 router has Ethernet ports built in. Older Starlink routers need a Starlink Ethernet adapter, which goes between the Starlink dish’s cable and the Starlink router and gives you an Ethernet port.
Run an Ethernet cable from the Starlink router (or the Starlink Ethernet adapter) to the Ethernet port on your Ubuntu computer. If your computer has no Ethernet port, use a USB to Ethernet adapter. Ubuntu starts using the cable connection on its own, and you should see it in the System Menu under “Wired Connection”. For any setup that pairs Wi-Fi with a cable, see how to combine Wi-Fi and Ethernet on Ubuntu.
Step 2: Connect Your Linux Computer to Your Cable or DSL Wi-Fi Network
Click the arrow in the top right corner (the System Menu), then Wi-Fi, then Select Network, and pick your cable or DSL Wi-Fi network. Type its password if it asks for one.
Step 3: Download Speedify for Linux to Use Both Internet Connections at Once
Download and install Speedify for Linux. When it runs, Speedify finds every internet connection your computer has and starts using them together. You should see both of them in Speedify: your Starlink internet connection over Ethernet, and your cable or DSL internet connection over Wi-Fi, each with its live download and upload speed.
Click either internet connection in Speedify to see its stats, set a data limit, or change how Speedify uses it. If your cable or DSL plan has a data cap, set it to Backup, and Speedify only uses it when Starlink drops.
Speedify also puts video calls and streams first, so they don’t stutter, buffer or disconnect when your Starlink dish switches satellites or something briefly blocks its view of the sky.
Speedify needs both internet connections plugged in and working: with Starlink alone, it can’t make downloads and uploads faster or stop dropouts. With both, your Linux computer gets faster, more reliable and more secure internet. The same works with two Starlink connections on Linux.
