Mac: Use a Secondary Cable / DSL Wi-Fi Connection Together with Your Starlink Ethernet Link
Yes, you can use Starlink and your cable or DSL internet at the same time on a Mac. Plug your Mac into the Starlink router with an Ethernet cable, connect your Mac to your cable or DSL Wi-Fi network, and let Speedify use both internet connections together. With two Starlink dishes instead, see how to combine two Starlink connections on a Mac.
Speedify is an app that uses all of your internet connections at the same time. With Starlink and cable or DSL together, you get the speed of both, and if one of them drops, Speedify switches your traffic to the other automatically. Each line covers for the other only while both are connected: on Starlink alone, Speedify works as an encrypted VPN and cannot stop Starlink itself from dropping. Below: the three steps on macOS. On Linux, follow Starlink with cable or DSL on Ubuntu.
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 a Mac
You need an Ethernet cable (and an adapter if your Mac has no Ethernet port), the name and password of your cable or DSL Wi-Fi network, and the Speedify app.
Step 1: Connect Your Mac to the Starlink Router with an Ethernet Cable
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 Mac. In most cases, your Mac connects to the internet on its own. MacBook Air and MacBook Pro models have no Ethernet port, so use a USB-C to Ethernet adapter, or a Thunderbolt to Gigabit Ethernet adapter.
Step 2: Connect Your Mac to Your Cable or DSL Wi-Fi Network
Click the Wi-Fi icon in the menu bar. (If Wi-Fi is off, choose “Turn Wi-Fi on.”) Pick your cable or DSL Wi-Fi network from the list, and type its password if it asks for one.
Step 3: Download Speedify to Use Both Internet Connections at Once
Download and install Speedify on your Mac. When it runs, Speedify finds every internet connection your Mac 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, at home, at work or on the road, your Mac gets faster, more reliable and more secure internet. With no DSL line, you can add an Android phone as a second internet connection instead.
