The good kind of redundancy…
A redundant internet connection keeps you online when one connection fails, and Speedify’s Redundant Mode takes the idea further: it sends all of your data over every connection at the same time and delivers whichever copy arrives first.
Speedify is an app that combines Wi-Fi, 4G/5G cellular, Ethernet, Starlink and satellite internet connections into one faster, more reliable connection. With Redundant Mode on, the connection stays consistent even when each individual 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.
Speedify combines every connection you have into one faster, steadier one

Redundant Mode in Practice: Train Wi-Fi Plus 4G LTE Without Dropped Packets
Speedify user David Weiss tried Redundant Mode within a week of its launch and wrote in to say how much more reliable his internet had become.
No matter which carrier you use, you will sometimes get disconnected on an Amtrak train. When Speedify sends all of your data over both the train Wi-Fi and your 4G LTE connection, either one can come and go without a single packet being dropped. If your internet connections are flaky, speed up and slow down, or randomly drop packets, Redundant Mode smooths over the problem and gives you a consistent connection.
Redundant Mode Uses More Data on Each Connection
Because Redundant Mode sends a copy of your traffic over every connection, each connection carries the full load. On a 4G/5G cellular plan with a data cap, that uses data faster than Speedify’s default mode, which splits traffic across connections instead of copying it. Use Redundant Mode for calls and live streams where a dropout costs you, and the default mode for everyday browsing and downloads.
