Now that you can see all the devices, you can start managing them. Click the Redirecting/Spoofing icon, which is usually the one just to the right of the Network Discovery icon. This activates the ARP spoofing engine. Once it is enabled, you can right-click on any device in the list to set its bandwidth limits.
While the portable version exists, the V3.0.0 release includes an MSI installer. Run SelfishNetV3_Installer.msi and follow the on-screen instructions. The installer places the required files in:
That said, the software isn’t perfect. Beta-level stability, outdated design, and limited advanced features may steer power users toward alternatives like NetLimiter or NetCut. But for basic bandwidth control, SelfishNet remains an effective, free solution.
Technically, SelfishNet acts as a man-in-the-middle or utilizes ARP (Address Resolution Protocol) spoofing techniques to intercept and control traffic packets. By doing so, it can effectively throttle the connection speeds of other devices without requiring access to the router's administrative settings. selfishnet v3.0.0 windows
SelfishNet is a portable application, meaning it doesn't require a traditional installation process that modifies your Windows registry. After extracting the ZIP file, you can run the executable directly. This makes it easy to use from a USB drive and ensures it leaves minimal traces on your system.
SelfishNet v3.0.0 for Windows provides a simple, desktop-based solution. This lightweight network management tool gives you direct control over your local area network (LAN) by allowing you to limit or completely block internet access for specific devices. What is SelfishNet v3.0.0?
Because of how SelfishNet operates, Windows Defender or third-party antivirus suites (like Avast, Kaspersky, or Malwarebytes) may flag the software as a Trojan or a hacking tool. If you downloaded the file from a verified, reputable source, you will need to add an exclusion for the SelfishNet folder within your antivirus settings to prevent it from being quarantined. Now that you can see all the devices,
After installation, right-click the SelfishNet.exe file and select "Run as administrator." This is essential for the application to interact with network protocols. How to Use SelfishNet v3.0.0
The "secret sauce" behind SelfishNet's capabilities is a networking technique known as . To understand this, it's helpful to visualize the network's internal communication protocol:
ARP poisoning forces a single computer to handle the routing overhead of multiple devices. This often leads to packet loss, increased latency (ping spikes), or complete network crashes if the host computer's hardware cannot handle the traffic load. 3. Security Mitigations Once it is enabled, you can right-click on
To restrict a device, click into the Download Limit or Upload Limit columns next to its IP address. Type in your desired maximum speed in Kilobytes per second (e.g., typing 50 limits that device to roughly 0.4 Mbps).
View active download and upload speeds for every device in real-time to identify bandwidth hogs.
Once the main graphical user interface (GUI) opens, you will notice that the device list is empty.
: Necessary for the legacy UI wrapper dependencies to initialize without crash logs.
SelfishNet is a classic network administration tool designed for Windows. It allows users to monitor all devices connected to their current WiFi or ethernet network.
