Speedify Uses a Backup Cable or DSL Connection Alongside Starlink on Windows to Keep You Online
This guide covers why a cable or DSL line is a strong backup for Starlink on Windows, how Speedify manages both internet connections, and how to set up Speedify in three steps.
Starlink disconnects all the time for ALL Starlink users. The Speedify Starlink Index report found that Starlink connections are down for an average of ~33 min per day. Plus, all Starlink dishes experience small drops and packet loss every 15 seconds, when the moving Starlink satellites hand off the connection to the next satellite overhead.
The best way to fix Starlink's connection drops is to combine your Starlink connection with another internet connection, such as 4G/5G cellular, cable, fiber, DSL, or another Starlink connection. Speedify makes this possible with channel bonding.
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.

Why Combine Starlink Internet with Cable or DSL on Windows
Starlink and cable or DSL broadband run on entirely separate infrastructure. Starlink uses low-Earth-orbit satellites. Cable and DSL use ground-based coaxial cable or telephone line networks maintained by local ISPs. A Starlink outage from weather or satellite congestion will not affect your cable or DSL connection, and a local ISP outage or line issue will not affect Starlink.
Running both through Speedify on your Windows PC means you have two independent paths active at all times. During normal operation, Speedify uses both connections to deliver the combined upload and download capacity of Starlink and cable or DSL. If one drops, the other takes over instantly without any manual intervention on your part.
This setup is especially useful for home offices and small businesses that already pay for a cable or DSL connection and want to add Starlink without losing the reliability of their existing broadband.
How Speedify Manages Starlink and Cable or DSL on Windows
Speedify runs on your Windows PC and monitors your Starlink and cable or DSL connections simultaneously. Speedify tracks latency, packet loss, and available bandwidth on each connection and adjusts traffic distribution in real time.
When both connections are performing well, Speedify routes traffic across both and delivers up to 95% of their combined upload and download capacity. When one connection degrades or goes offline, Speedify shifts all traffic to the remaining connection at the packet level. Active calls, file transfers, and video sessions continue without interruption.
Speedify also encrypts all your internet traffic across both connections, keeping your data protected on every path it takes.
How to Combine Starlink Internet with Cable or DSL on Windows with Speedify
Step 1: Connect to Your Cable or DSL Router
Connect your Windows PC to your cable or DSL router using an Ethernet cable, or connect via Wi-Fi. Confirm the connection is active in your system tray network indicator.
Step 2: Connect to Your Starlink Network
Connect your Windows PC to your Starlink router using a second Ethernet cable, or via Wi-Fi if you are using Ethernet for your cable or DSL connection. If both connections use Wi-Fi, a USB Wi-Fi adapter will be required for one of them.
Step 3: Download and Run Speedify
Download Speedify and install it on your Windows PC. Speedify will detect both active internet connections and start bonding them immediately. No manual routing setup is needed.
Speedify handles everything from that point: combining Starlink and cable or DSL for faster upload and download speeds, monitoring for drops, failing over automatically, and encrypting all traffic.
Who Should Use Speedify to Combine Starlink and Cable or DSL on Windows
- Home office workers with both a cable or DSL subscription and Starlink who want to use both for maximum upload and download speed and reliability
- Small businesses using Windows PCs that need a backup internet connection in case their primary broadband goes down
- Content creators and streamers who need the combined upload bandwidth of two separate internet connections
- Anyone in a location where cable or DSL is unreliable and Starlink is a more stable alternative that still needs a backup
- IT teams managing Windows workstations who want software-based bonding and failover without replacing existing router hardware
Speedify Also Monitors Your Starlink Dish Status on Windows
Speedify displays real-time Starlink dish alerts in the app dashboard on your Windows PC. If your dish has a stuck actuator motor, a non-vertical mast, or is experiencing thermal throttling, Speedify shows the alert in the app. The alert appears when the condition has persisted for at least 15 seconds and clears once resolved.
Speedify lets you monitor both your internet connections and your Starlink hardware from a single dashboard.
