Because SelfishNet is not an open-source project maintained on a central repository (like GitHub) and is often flagged by antivirus software as a "HackTool," many users disable their antivirus to install it. This is a primary vector for malware infection.
SelfishNet V2 is a free, lightweight Windows application developed by a third-party coder known as Momo. It operates on the principle of ARP (Address Resolution Protocol) spoofing. In simple terms, it tricks the router into thinking that your computer is the gateway for other devices. This allows the software to intercept, monitor, and throttle the internet connection of any device on your network—including smartphones, gaming consoles, and smart TVs.
The "V2" version was a significant upgrade from the original SelfishNet. It introduced a more stable interface, better compatibility with modern Windows operating systems (Windows 7, 8, and 10), and improved filtering algorithms to reduce network collisions.
Q: Is SelfishNet safe to download? A: Only if downloaded from a reputable source. Because the tool is often distributed via forums and third-party aggregators, it is commonly infected with malware. Always scan the file with VirusTotal before running it.
Q: Why does my antivirus block it? A: SelfishNet performs ARP spoofing, which is a technique used by hackers to perform "Man-in-the-Middle" attacks. Antivirus software blocks it to protect the network, even if your intent is benign bandwidth management.
Q: Does SelfishNet work on Windows 10/11? A: The original V2 is quite old. While it generally works on Windows 10, users often face issues with driver compatibility for the packet capturing driver (WinPcap or Npcap). It is recommended to install Npcap (in WinPcap compatible mode) for the tool to function correctly on modern Windows versions.
Q: Is there a safer alternative? A: For legitimate network management, using QoS settings on your router is the safest and most effective method. For pen-testing, tools like Netcut (the official version) or Kali Linux tools (arpspoof, bettercap) are more transparent and maintained.
SelfishNet is a lightweight networking tool used to monitor and manage internet bandwidth for devices on a local area network (LAN). While the original version was popular for older Windows systems, the SelfishNet v2 (and subsequent v3 updates) remains a go-to utility for users needing granular control over who uses their Wi-Fi and how much speed they get. What is SelfishNet v2?
SelfishNet is a "portable" network management application that doesn't require a traditional installation. It works by using ARP Spoofing (Address Resolution Protocol), which essentially allows your computer to "shout" over the router and tell other devices that your PC is the gateway. Once this link is established, all network traffic flows through your device, giving you the power to:
Identify Devices: See every IP and MAC address currently connected to your Wi-Fi.
Limit Bandwidth: Manually set a maximum download or upload speed for specific users.
Block Access: Completely cut off a device's internet connection with a single click. SelfishNet v2 Download & Requirements
Because SelfishNet is no longer officially maintained by a single corporate developer, it is primarily hosted on community platforms like GitHub or third-party software hubs like Software Informer.
Essential Dependencies:To run SelfishNet v2 successfully on modern systems, you must have these two components installed first:
WinPcap Drivers: This is the most critical requirement; the software will not detect network adapters without it.
.NET Framework 3.5: Many versions of SelfishNet rely on this older framework to launch. Installation & How to Use
Since the program is portable, the setup involves a few manual steps to ensure compatibility with Windows 10 and 11:
Extract the Files: Use a tool like WinRAR or 7-Zip to extract the downloaded ZIP folder.
Enable Admin Privileges: Right-click the SelfishNet.exe file, go to Properties > Compatibility, and check "Run this program as an administrator".
Select Your Adapter: Upon launching, you will be prompted to select your network interface (usually your Wi-Fi or Ethernet card) from a dropdown menu. Scan and Control:
Click the Network Discovery button (often an icon with a magnifying glass) to list all devices.
Click the Lightning Bolt icon to start the redirection service.
Enter values in the Download/Upload Cap columns and press Enter to apply limits immediately. Important Safety & Performance Notes
Temporary Solution: SelfishNet settings are not permanent. If you close the program or turn off your computer, all network limits will revert to default.
Potential for Lag: Since traffic is routed through your PC, your own performance might be affected if you are managing a large number of devices.
Security Risks: Use caution when downloading from third-party sites. Always scan the .exe with updated antivirus software, as some modified versions of these tools can contain malware.
For users looking for a more modern, officially supported alternative, the newer SelfishNet v3 is available on GitHub and offers better compatibility with the latest Windows updates. selfishnet v2 download

SelfishNet v2 is a popular network management utility for Windows that allows users to control internet bandwidth distribution across a local area network (LAN)
. It is primarily used to identify all devices connected to a Wi-Fi or wired network and limit or completely block their internet access. Key Features Network Discovery
: Automatically scans and lists every device (PC, smartphone, tablet) connected to your router, showing their IP and MAC addresses. Bandwidth Control
: Enables you to set specific download and upload speed limits for individual devices. Internet Blocking
: Features a "Block" checkbox to instantly cut off internet access for specific users without disconnecting them from the Wi-Fi. Real-time Monitoring
: Displays the current data usage (Download/Upload) for every active device on the network. How it Works SelfishNet utilizes a technique called ARP Spoofing
(or ARP Poisoning). By sending forged ARP messages, the software convinces other devices on the network that your computer is the router (gateway). This forces all their traffic to pass through your machine first, allowing the software to throttle or drop packets before forwarding them to the actual router. Critical Considerations Safety and Security
: SelfishNet is an older, "abandonware" tool. It does not have an official website, meaning it is often hosted on third-party file-sharing sites. Use extreme caution
and scan any download with reputable antivirus software, as these installers are frequently bundled with malware. System Requirements : It requires (or the more modern
) to be installed to capture and inject network packets. It is compatible with Windows 7, 8, 10, and 11, though it often requires "Run as Administrator" mode to function. Ethics and Legality
: Throttling or blocking others' internet without permission may violate "Acceptable Use Policies" in workplaces or schools and can be considered a form of cyberattack in certain jurisdictions. Common Troubleshooting
