What Is WAN Aggregation for Starlink? How Speedify Combines Your Internet Connections

Speedify Combines Starlink with Your Other Internet Connections for Business Networks

WAN aggregation, also called WAN bonding, means using several internet connections at once as if they were one faster internet connection. Speedify does this in software for businesses on Starlink: it uses your Starlink internet connection together with 4G/5G cellular, wired broadband and Wi-Fi, and if one of them drops, it switches your traffic to the others automatically. If you are comparing products, see this WAN bonding software buyer’s guide.

You don’t need a special appliance: Speedify runs on the computers you already have, or on a router for the whole site. Contact Us to plan your setup.

What Is WAN Aggregation, and What Does It Mean for a Business on Starlink?

A WAN connection is simply an internet connection coming into your site: Starlink, a cable or fiber line, or 4G/5G cellular. WAN aggregation adds them together. For a business with Starlink and other internet connections, Starlink’s speed then adds to the speed of the others, instead of Starlink being a separate internet connection that each device either uses or doesn’t.

Many routers that take several internet connections send each download, call or app session over just one of them. Different sessions go over different internet connections, so the total speed goes up, but one video call or one upload still only gets the speed of one internet connection.

Speedify splits the data of each session across all your internet connections at once. A single video upload, company VPN connection or live stream gets speed from every internet connection at the same time, so your team gets close to the combined upload and download speed of all of them, not just the speed of one.

For example, if Starlink gives your business 150 Mbps, a wired broadband line gives 100 Mbps and 4G/5G cellular gives 80 Mbps, that’s 330 Mbps in total. In good conditions, Speedify can give a single session nearly all of those 330 Mbps. These are example figures, not measurements.

How Speedify Combines Starlink with Your Other Internet Connections

Speedify sends all your internet traffic, encrypted, through a Speedify server (see how Speedify combines internet connections). Along the way, Speedify checks the speed, delay and lost data on each internet connection many times a second, and spreads your traffic across all of them based on how each one is doing right now.

What that means in practice:

  • One session uses every internet connection. The data from a single download or call goes over several internet connections at the same time. The Speedify server puts it back together in the right order, so your apps see one fast internet connection.
  • Speedify shifts traffic away from a slow Starlink. When the Starlink network is busy and the delay goes up, Speedify sends less over Starlink and more over wired broadband or 4G/5G cellular, on its own. When Starlink recovers, Speedify shifts traffic back.
  • Sessions keep going when an internet connection fails. When one internet connection drops completely, the data it was carrying moves to the others right away. Calls don’t drop, VPN connections stay up, and active sessions don’t restart.
  • You choose how each internet connection is used. On Speedify Teams plans, network admins set each internet connection’s priority (Always, Secondary, Backup or Never), set data limits on metered connections like 4G/5G cellular, and set speed limits per internet connection.

Ways to Combine Starlink with Other Internet Connections Using Speedify

  • Starlink plus wired broadband. For a business with Starlink and a cable, fiber or DSL line, Speedify uses both together, for more combined speed than either one alone. Each one covers for the other when it drops.
  • Starlink plus 4G/5G cellular plus wired broadband. The steadiest of these setups. Any one internet connection can fail without taking your site offline, and all three add to your upload and download speed while they work.
  • Two Starlink dishes plus 4G/5G cellular. For remote sites without wired broadband, two Starlink dishes and 4G/5G cellular give you the most satellite speed plus a cellular backup, with Speedify using all three at the same time. See how to manage two Starlink dishes at once with Speedify.
  • Starlink with metered 4G/5G cellular as a backup. To keep cellular data costs down, set a data limit on 4G/5G cellular. Cellular adds to your speed until it reaches the limit, and after that Speedify keeps it for backup only, with Starlink as your main internet connection.

How to Set Up Speedify for Starlink WAN Aggregation

Option 1: The Speedify App on Each Computer or Phone

  • Give each device two internet connections. A computer joins Starlink over Wi-Fi or an Ethernet cable, and gets its second internet connection from an Ethernet cable to your other router, a USB cellular modem, a phone plugged in by USB, or a USB Wi-Fi adapter (a computer’s built-in Wi-Fi joins one network at a time). A phone uses Starlink Wi-Fi plus its own 4G/5G cellular.
  • Install the Speedify app. Speedify runs on Windows, macOS, Linux, iOS and Android.
  • Speedify finds every internet connection on the device and starts using them together on its own. You don’t need to set up each internet connection by hand.
  • Use Speedify Teams to set priorities, add data limits to metered internet connections, and manage every team device from one place.

Option 2: Speedify on a Router for the Whole Site

  • Connect all your internet connections (Starlink, wired broadband, 4G/5G cellular modems) to a router that runs Speedify, such as a supported OpenWrt router. The Miri X510 router, powered by Speedify, takes several internet connections and is built for whole-site setups.
  • Speedify uses all the connected internet connections at the router. Every device on the network gets the combined speed and the automatic switching when one drops, without installing anything on each device.
  • Manage priorities, data limits and each internet connection’s status from the Speedify for Routers dashboard.

A router is the right choice when the whole site has to stay online, including cameras, sensors, networked equipment and anything else that can’t run the Speedify app.

Which Businesses Need Starlink WAN Aggregation with Speedify

  • Businesses with several internet connections but devices that use only one at a time. If you have Starlink plus another internet provider, Speedify puts both to work right away, and each covers for the other.
  • Remote sites with many people online at once. A remote office or field site where many people are on video calls, uploading files and using cloud apps at the same time needs more speed than one Starlink dish gives. Speedify adds your other internet connections to it.
  • Businesses that promise uptime to their clients. If you owe clients or your own teams dependable internet, you can’t rely on one internet connection. With Speedify, no single internet connection can take you offline.
  • IT teams replacing or adding to multi-connection hardware. Speedify is software, so it runs on router hardware you already have or on devices built for it, without buying a dedicated appliance.
  • Managed service providers (MSPs) with many client sites. Use Speedify the same way at every client site, managed from the Speedify Teams dashboard, whatever mix of internet connections each site has.

Speedify Plans for Businesses Using Starlink with Other Internet Connections

Speedify Teams ($89.99 per user per year, 5-user minimum) gives network admins one dashboard for the whole organization: internet connection priorities, data limits, usage monitoring and team devices.

For businesses that need servers of their own, static IP addresses and port forwarding, Speedify Dedicated Servers are available as a managed option, and they come with an uptime promise: one free day of service for every hour of downtime. For businesses that must keep data in a specific country or need a specific network design, Speedify Self-Hosted Servers let your team run Speedify traffic through your own private servers.
