Check the respective boxes within the GUI and customize the parameters to simulate distinct network environments: 1. High Latency (Lag) Enable Lag . Parameter: Set Delay to 150 (milliseconds).
: Right-click clumsy.exe and select Run as Administrator . This is required because Clumsy leverages the WinDivert library to intercept system-level network traffic. Core Functionalities
If Clumsy reports it is running but no packet manipulation occurs, your filter string may contain syntax errors or target the wrong protocol.
inbound and outbound (captures all local development traffic). clumsy 04 v2 install download
One of the greatest strengths of clumsy is its . Unlike many network tools that require complex driver installations or registry modifications, clumsy is entirely self‑contained. Here’s how to get it up and running:
: Delays packets for a set amount of time (up to 3,000ms).
// Example Filter Syntax ip.DstAddr == 127.0.0.1 and tcp.DstPort == 8080 Use code with caution. Useful Filter Templates Check the respective boxes within the GUI and
inbound and ip.DstAddr == 127.0.0.1
Here's what I can tell you:
for cluster management, but it is unrelated to the lag simulation tool. GitHub Pages documentation common filter strings to use with clumsy for specific games or network tests? Download - GitHub Pages : Right-click clumsy
Adjust parameters in real-time if necessary. Clumsy updates packet manipulation rules instantly without requiring a restart.
Modern applications — whether web services, mobile apps, online games, or IoT devices — must function reliably under real‑world network conditions. Real networks are far from perfect: cellular connections experience high latency and packet loss, Wi‑Fi signals fluctuate, and public networks often have severe bandwidth limitations. If your application only works under ideal lab conditions, it will fail in the hands of real users.
Which (high ping, packet loss, or disconnection) are you trying to recreate?
Finding a safe, legitimate download source is crucial when dealing with any network‑level tool. Clumsy is open source and free to use, but you must be careful to download it from official or trusted sources only.
A: No, Clumsy is a Windows-specific tool that relies on the WinDivert library, which is only available for Windows.
