The TCP Optimiser Module is a root-level network tool for Magisk and KernelSU that automatically switches TCP congestion algorithms based on the active connection type. It improves overall internet speeds by dynamically applying different configurations for Wi-Fi and cellular networks.

In my daily usage, I noticed a massive jump in upload speeds on Wi-Fi by forcing BBR, while keeping standard Cubic for cellular to avoid data throttling. I've been running this on my daily driver to automatically juggle these network profiles, and the included WebUI makes tweaking queuing disciplines incredibly easy without touching text files.

Automatic interface detection switches TCP algorithms the second your phone moves from Wi-Fi to mobile data.
Push data faster by enabling maximum initcwnd and initrwnd values to improve initial connection burst speeds.
The WebUI integration allows full control over your network tuning directly inside KernelSU, APatch, or the KsuWebUIStandalone app.
Force connection resets using an optional toggle to kill active downloads and uploads for a clean state when changing networks.

Support & Requirements

Root: Magisk, KernelSU, or APatch
Android: Compatible with all modern Android versions supporting the root managers above.

How to Install

Download the TCP Optimiser .zip file from the GitHub repository.
Flash the module directly through the Magisk or KernelSU manager app.
Reboot your device to initialize the background switching service.
