Channel Bonding > Load Balancing
If you have multiple Internet connections, and you’re looking for ways to combine them to increase speed and reliability, you can choose between load balancing or channel bonding software. A load balancer runs locally on your PC and spreads sockets amongst multiple Internet connections to increase overall performance. The big caveat here though is that applications need multiple sockets to see big improvements, as no individual socket can be sped up beyond your fastest available Internet connection.
General web browsing and BitTorrent utilize lots of sockets, so a load balancer works fine in these cases. But, load balancers can’t speed up a streaming video, VPN, or single large file upload/download as each of these activities happen over a single socket.
Quick answer
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.
Learn more →Cable / DSL
Best for fixed locations. Different network, so outages rarely overlap.
Learn more →Second Starlink
Adds redundancy and throughput for remote sites or heavy usage.

Speedify Feature · Pair & Share
Speedify Pair & Share: share cellular between your devices, both ways
Most hotspots give. Speedify's Pair & Share gives and takes. Two devices running Speedify pair up and each uses the other's cellular connection simultaneously, so you both get faster uploads, faster downloads, and a steadier connection. No extra hardware, no new data plans, no setup beyond a tap.
Learn how Speedify's Pair & Share works ›More speed
Every device you pair with adds its cellular to yours, and yours to theirs.
Stays connected
If a paired device drops out, Speedify keeps you online on the remaining links.
Always private
Every shared connection runs through AES-256 encryption. Your traffic is yours.
No new gear
Runs on devices already running Speedify, over your local network. Pair once, reconnects automatically.
Speedify is a channel bonding service
Channel bonding makes it possible to go one level deeper than a load balancer and spread packets amongst multiple Internet connections. This means that Speedify can speed up everything you do online.
Once connected to one of our Speed Servers in the cloud, Speedify intelligently divides all your web traffic amongst available Internet connections in order to maximize performance. By splitting traffic at the packet-level even large single socket transfers such as VPNs, streaming movies, and uploading and downloading files can be given a major speed boost!
Speedify also has robust failover capabilities, so even if you unplug one of your Internet connections during an important upload or download your transfer will keep on transferring!
