The Ultimate Guide to SelfishNet v3.0.0 for Windows: Take Control of Your WiFi Network
Think of it as a way to allocate bandwidth on a shared connection. For example, if one device in your home is using excessive bandwidth for large downloads or video streaming, SelfishNet can be used to cap its speed. This can help ensure that other activities, like online gaming or video calls, maintain good performance. It can also be used to identify all connected devices, which is useful for security auditing to see if any unauthorized devices are on your Wi-Fi. : Check the "Block" box next to a

: Scans your network and lists all connected devices by IP and MAC address.
In shared living environments—such as university dormitories, shared apartments, or open-plan offices—a single user engaging in high-bandwidth activities (like 4K streaming, large game downloads, or video conferencing) can cripple the latency for everyone else. Standard router configurations are often inaccessible to tenants or require administrator passwords. Selfishnet v3.0.0 democratizes network control by exploiting how standard, unsecured networks handle Address Resolution Protocol (ARP). By sending ARP replies to the gateway, Selfishnet convinces the router that the user’s computer is the legitimate path for all traffic. Once this "Man-in-the-Middle" (MITM) position is established, the software acts as a gatekeeper, throttling or blocking competing devices.
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.
