To ensure the software works correctly on modern systems like Windows 10 or 11:

Install WinPcap first: The program will not detect network adapters without these drivers.

Run as Administrator: Right-click the executable, go to Properties > Compatibility, and check "Run this program as an administrator".

Select the Right Adapter: Upon launching, you must choose your active network adapter (Wi-Fi or Ethernet) from the drop-down menu.

Activate Redirection: Click the "Network Discovery" (antenna icon) to find devices, then the "Start Redirecting" (lightning bolt icon) to begin controlling them. Reliable Sources for Download

Because SelfishNet is no longer officially maintained by its original developer, it is often hosted on community sites. It is highly recommended to use reputable repositories to avoid malware: Abelmez's GitHub Repository Nov0caina's GitHub (Installer version)

Note: Always scan the downloaded file with a tool like Windows Defender or Bitdefender before running.

Selfishnet v3.0.0 for Windows is a lightweight, portable network management tool designed to monitor and control bandwidth usage across all devices connected to your local network. It is particularly popular for its ability to "kick" users off Wi-Fi or strictly limit their download and upload speeds. Key Features & Performance

Device Discovery: Scans your network and lists all connected devices by IP and MAC address. Why it’s notable

Bandwidth Throttling: Allows you to set specific KB/s limits for both upload and download speeds per device.

Network Blocking: Includes a "Block" checkbox to completely cut off internet access for specific users.

Portability: It is a standalone utility that does not require a formal installation process, though it needs administrative rights to function. Technical Requirements

To run Selfishnet v3.0.0 effectively on modern versions like Windows 10 or 11, you must have several dependencies installed: WinPcap: Essential driver for capturing network packets.

.NET Framework 3.0/3.5: Often required for the software to launch.

Administrator Privileges: You must right-click and "Run as administrator" for the network scanning and blocking features to activate. The Verdict

Selfishnet is highly effective for its size but lacks the polish of modern network management software. Its biggest drawback is that it is not a permanent solution; settings only remain active while the application is open on your PC. Additionally, because it uses ARP spoofing to control traffic, some modern antivirus programs or routers may flag it as malicious or block its functionality.

If you are a security researcher, ethical hacker, or student working in a controlled lab environment (e.g., your own router and devices), here is a neutral, educational write-up about SelfishNet v3.0.0:

Do not cut off the router. Cutting the router’s IP (usually 192.168.1.1 or 192.168.0.1) will immediately disconnect the entire network, including yourself.

Use Windows Task Scheduler to launch SelfishNet.exe --auto-start --profile "Limit Guests" at 8:00 PM (peak hours) and close it at 12:00 AM. This provides automated bandwidth shaping without manual input.

Combine SelfishNet with a MAC changer (e.g., Technitium MAC Address Changer). If the network admin bans your MAC, you change it, reinstall SelfishNet, and resume control.
