How to Combine Starlink and Ethernet on Windows PC with Speedify

Improve Bandwidth and Latency by Combining Starlink with Ethernet on Windows

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 wired Ethernet network and then use Speedify to combine them.

You can get a secondary Internet connection via the same or a different ISP.  Examples include another Starlink, DSL, cable, or cellular connections. Speedify can bond your Starlink satellite connection with any number or combination of other Internet connections and will intelligently distribute your online traffic among them for optimal performance. Plus, if you get disconnected from Starlink in the middle of an important video call or file transfer, Speedify will seamlessly failover to your other working Internet connection(s) without skipping a beat.

NOTE: For best results, use Internet connections from different sources. In general, joining the same upstream network multiple times (such as the same router via Ethernet and Wi-Fi) will not improve performance.

Speedify Starlink Index — real-world performance from 6,209 Starlink users: 2.4% downtime, about 34 minutes a day for always-on connections

Starlink goes down every day.
Here’s what that actually looks like.

Speedify passively monitors every connection it bonds. These figures come from 6,209 Starlink users over 14 days — compared in real time against the other connections on the same devices. No speed tests, no lab conditions.

Use Speedify to stay online during satellite handoffs every 15 seconds

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. 

Speedify makes your uploads and downloads faster, more reliable, and more secure.

Speedify combines Wi-Fi, 4G / 5G cellular, Ethernet, Starlink, and other satellites for faster internet uploads and downloads

Speedify is the only software app that combines Wi-Fi, 4G / 5G cellular, Ethernet, Starlink and other satellites at once for secure, faster, and more reliable internet uploads and downloads so you stay online without interruptions.

Speedify will automatically detect and start using any available Internet connections on your device while intelligently distributing your online traffic between them for optimal performance. If you need help we have quick start guides available for most common set ups.

Speedify gets you faster uploads and downloads from the devices around you 

Speedify's Pair & Share feature lets you and the devices around you pair up and share 4G/5G cellular both ways, so every paired device gets faster uploads, faster downloads, and a steadier internet connection. All sides share and use each other's cellular at once, unlike a personal hotspot, where one device gives and the rest take.

Speedify's Pair & Share feature runs over the local network between devices already running Speedify, with no extra hardware and no new data plans. Speedify creates an encrypted pool of shared 4G/5G cellular connections across all paired devices. Each device taps into that shared pool of combined connections for faster upload and download speeds and a more reliable internet connection.

3 Steps to Combine Starlink and Wired Ethernet on a PC Using Speedify

Step 1: Connect to Your Starlink 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.

Verify that your Wi-Fi is enabled on your PC and connected to a network.

Click on the Wi-Fi symbol in the lower right corner of the taskbar (systray). If you’re not already connected to a Wi-Fi hotspot, turn on Wi-Fi by clicking on the tile in the lower left side of the pop-up menu then select the Wi-Fi hotspot associated with your Starlink connection and enter the password to connect.

Step 2: Connect Your Ethernet Cable to Your PC

Connect an Ethernet cable between your router or modem and the Ethernet port on your PC. If your computer doesn’t have a built-in Ethernet port, try using a USB to Ethernet adapter instead.

In most cases, you will connect to the Internet automatically. If it doesn’t work, see some troubleshooting options here.

Step 3: Download and Install Speedify

Last but certainly not least, download and install Speedify. Once running, Speedify will automatically detect your Starlink connection and any other available Internet 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.
