Combine Wi-Fi, Cellular, Fiber, Cable, DSL, Satellite and Other Connection Types
Want faster upload and download speeds and more reliable internet? Run three or more connections – like Wi-Fi, 4G/5G cellular, Ethernet, and Starlink or satellite – at the same time.
Speedify is an app that combines two or more internet connections at once – such as Wi-Fi, cellular, Ethernet, and satellite – so you get faster uploads and downloads and stay online if one connection drops out. It works on your PC or Mac with no extra hardware.
<1 sec
With Speedify, your internet stays on when one connection fails.
When one of your internet connections drops, Speedify shifts your traffic to your remaining connections in under a second — so calls don’t cut out and downloads don’t stall.
Should you have a backup 4G, 5G, Starlink, or cable internet connection?
Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.
4G/5G cellular
Works anywhere. Just a SIM or hotspot — no installation needed.

Best for fixed locations. Different network, so outages rarely overlap.

Adds redundancy and throughput for remote sites or heavy usage.

What Types of Internet Connections Can I Combine with Speedify?
Speedify is an app that uses patent-pending link aggregation technology to take advantage of practically any internet connection that your computer or mobile device is able to connect to. This includes multiple cable, DSL, Wi-Fi, 4G/5G devices, and tethered smartphones.
With Speedify, you can combine 2, 3 or more Wi-Fi networks, 2, 3 or more 4G/5G dongles, Ethernet connections, tethered phones or any combination of the above.
Don’t worry if your device requires additional configurations, like running dialer software for mobile broadband networks or logging into captive portals on Wi-Fi and ethernet networks at hotels or airports. Speedify will still use the connections once you follow the steps below.
Here are some types of internet connections you might be able to find depending where you’re located.
Requirements for Combining 3 Internet Connections at Once
The most important requirement when combining 3 Internet connections simultaneously with Speedify fast and secure bonding app is that they have to belong to different upstream networks. That means that you cannot connect to your home network through both Wi-Fi and wired ethernet, as they share the same upstream network. Instead, you should think about using your home network (through Wi-Fi or ethernet), a nearby public Wi-Fi, and your tethered phone or a cellular data USB adapter.
Also – depending on the types of connections you bond together, you may need additional network adapters / USB dongles connected to your computer. For example, if you’re combining 3 Wi-Fi networks, you can use any internal network card your computer has, but you’ll need 2 additional USB Wi-Fi adapters, as each Wi-Fi network adapter can only connect to one Wi-Fi network. Same goes for 4G/5G cellular USB dongles – you need one for each network.
5 Steps to Combine 3 Internet Connections on Your PC or Mac with Speedify Fast and Secure Bonding VPN
Briefly put: connect to the Internet through all available connections and run Speedify fast bonding VPN.
In the example below, let’s assume a typical example for the 3 Internet connections: your home network (via wired ethernet), a nearby public Wi-Fi hotspot, and your tethered smartphone. Here’s what you have to do to combine 3 Internet connections simultaneously:
- Install Speedify on your PC or Mac.
- Connect to your home network via wired ethernet. You can also connect via Wi-Fi, but in this case you will need an extra USB Wi-Fi adapter for the next step, as you cannot use the same Wi-Fi adapter to connect to multiple Wi-Fi hotspots.
- Connect to the nearby public Wi-Fi network using the built-in Wi-Fi adapter. If your computer doesn’t have one, you’ll need to get a USB Wi-Fi adapter.
- Connect your smartphone via USB to your computer and tether it. Alternatively, you can use a USB cellular data adapter.
- Start Speedify. You should see all 3 active connections on the main user interface. Once you activate Speedify and connect to a server in the cloud, you’re bonding 3 Internet connections at the same time!
Speedify Does More than Just Combine 3 Internet Connections at Once
Speedify is more than just a way to use and manage multiple internet connections on your device. It is also a mobile VPN service. It was designed for speed, so it won’t slow your device down. But it will encrypt all of your data and protect you from the dangers of using an unsecured public network.
