The good kind of redundancy…
Speedify is an app that combines two or more internet connections at once for faster speeds and staying online if one drops. Its Redundant Mode keeps a connection rock-solid by sending all your data over every connection at the same time and delivering whichever copy arrives first.
The result is consistent, reliable internet even when each connection is flaky – pull the plug on one and, as long as another is working, not a single packet is lost. Here is Redundant Mode in action.
With Speedify, your internet stays on when one connection fails.
When one of your connections drops, Speedify automatically routes your traffic to your remaining connections — so calls don't cut out and downloads don't stall.
How do I use WiFi and 4G/5G cellular at the same time with Speedify?

Taking Redundant Mode for a Spin
Less than a week after launch, it’s safe to say that Redundancy Mode is a hit. Our new friend, David Weiss wrote us to say:
Why is David so excited? Because redundancy makes his Internet much more reliable. I’ve talked before about how, no matter which carrier you use, you will sometimes get disconnected on an Amtrak train. But, when Speedify sends all of your data over every connection, the train WiFi and your 4G LTE card can come and go without a single packet being dropped. In fact, with Speedify running on your Mac or PC, you could literally pull the plug on an Internet connection, and as long as one of the others is working, you wouldn’t lose a single packet. As David has discovered, if your Internet connections are flaky and tend to get faster and slower, or randomly drop packets, Speedify’s new Redundant Mode feature will smooth over your problems and give you a consistent, headache-free Internet experience.
