: Some security software may flag it due to its network-sniffing behavior (ARP spoofing), though it is generally considered safe if downloaded from reputable developers or help troubleshooting a specific connection error
This is a non-negotiable requirement. SelfishNet needs to manipulate low-level network protocols and intercept traffic. As a security measure, Windows requires administrative permissions for such operations. You must run SelfishNet as an Administrator for it to function properly.
Because SelfishNet routes data through your PC, if your computer suffers from hardware bottlenecks, high CPU utilization, or drops its wireless connection, it will interrupt the internet flow for every throttled device on the network.

The Ultimate Guide to SelfishNet v3.0.0 for Windows: Take Control of Your WiFi Network
While high-end routers offer Quality of Service (QoS) settings to manage this traffic, configuring them can be overly technical and restrictive. This is where comes in.
When bandwidth limiting isn't enough, SelfishNet allows you to block any device from accessing the internet entirely. With a few clicks, you can instantly cut off access to any connected device, preventing it from sending or receiving any data through your router. This can be a powerful tool for immediately stopping a bandwidth-hogging application or removing an unauthorized user from your network. : Some security software may flag it due
You must right-click the executable and select "Run as administrator" for the ARP spoofing to work. How to Use Selfishnet v3.0.0 Safely
I noticed you are setting up SelfishNet v3.0.0 on a Windows computer. Would you like a detailed guide on how to safely configure or troubleshoot common network adapter errors if your Wi-Fi interface isn't being recognized by the application? Releases · nov0caina/SelfishNet - GitHub
SelfishNet v3.0.0 is a network management tool for Windows that utilizes ARP (Address Resolution Protocol) spoofing to intercept data traffic on a local network. Unlike complex enterprise network management software, SelfishNet features a minimalist interface that requires no technical expertise to navigate. You must run SelfishNet as an Administrator for
SelfishNet V3.0.0 is a powerful double-edged sword. It showcases how fragile the classic Ethernet model is—anyone on your local network can, with minimal effort, intercept or block your traffic. The best defense against SelfishNet is not a better firewall, but like Dynamic ARP Inspection (DAI) on managed switches, port security, or using encrypted VPNs for all sensitive traffic.
Moreover, even on a home network, if an ISP's terms of service prohibit network manipulation or the use of third-party tools to manage bandwidth, using SelfishNet could technically be a violation of your service agreement. While enforcement of such clauses is rare for a home user, it is a legal reality worth keeping in mind. Finally, deliberately limiting or restricting another person's internet access without their consent could, in some extreme scenarios, be viewed as a form of harassment or cyberstalking.
Enter – a powerful, lightweight, and somewhat controversial network utility that puts the control back into your hands. But what exactly is this tool? Is it legal? How does it work on Windows 10 and Windows 11? And most importantly, how can you use it effectively?
