Selfishnet V3
Because Selfishnet V3 relies on low-level network packet manipulation, it cannot run as a standalone executable out of the box. It requires a specific driver framework to interact with your network interface card (NIC). Essential Prerequisites
Right-click the SelfishNet.exe file, go to Properties > Compatibility , and check "Run this program as an administrator" . This is mandatory for network packet manipulation.
: Features a "Block" checkbox that immediately cuts off internet access for a target device while keeping it connected to the local network.
: Preventing one device from consuming all the bandwidth (e.g., during large downloads) to ensure stable gaming or streaming for others.
This is the most critical dependency. Selfishnet requires the WinPcap driver (or the more modern Npcap ) to capture and inject network packets. Selfishnet V3
SelfishNet remains a "cult classic" for users who need a lightweight, no-frills way to limit or block internet access for other devices on their Wi-Fi. While it is highly effective for simple home networks, its aging architecture and reliance on older drivers make it a bit finicky to set up. Key Features Device Discovery:
In a shared network environment, whether at home or in a small office, limited bandwidth often becomes a source of frustration. is a widely recognized network management utility designed to give users granular control over their local area network (LAN) traffic. By using this tool, you can monitor connected devices, limit their upload and download speeds, or block their internet access entirely to ensure your own connection remains stable. What is Selfishnet V3?
An advanced endpoint monitor that allows you to review visual usage charts of your own local machine's data while offering remote monitoring capabilities for network anomalies.
A tool like WinRAR or 7-Zip is needed to extract the program files. Step-by-Step Setup Because Selfishnet V3 relies on low-level network packet
In an era where multiple devices are constantly connected to a single home or office network, internet speed often becomes a bottleneck. Streaming, gaming, and working from home simultaneously can lead to frustrating latency and slow download speeds. While router settings can provide some control, a popular, user-friendly tool has emerged to manage network traffic directly from a Windows desktop: .
When activated, Selfishnet sends forged Address Resolution Protocol (ARP) messages to the other devices on the network. This tricks those devices into thinking your computer is the router.
: WinPcap must be installed on your machine to handle low-level network packet captures. Software Framework : Microsoft .NET Framework 3.0 or higher.
: It typically requires WinPcap or Npcap to be installed to capture and inject network packets. Releases · abelmez/SelfishNet - GitHub This is mandatory for network packet manipulation
This is where Selfishnet V3 truly shines. You can set specific download and upload speed limits (measured in KB/s) for any device on your network. Watching 4K streams slowing everyone down? Limit that smart TV to 200 KB/s. Someone running massive downloads? Cap their connection so your gaming or work remains unaffected.
To limit speed, type specific numeric values into the or Upload columns (measured in KB/s) and hit enter.
While Selfishnet V3 is a powerful tool, it is essential to use it responsibly.
is a lightweight network management tool designed to give you complete control over your local network's bandwidth distribution. It is particularly popular for managing public or shared Wi-Fi connections where specific users may be hogging resources.
A user-editable field to enter a maximum upload cap (in KB/s). Empty means unthrottled.
It is generally safe for personal use, but because it uses "spoofing" techniques, many antivirus programs may flag it as a threat. Only download it from reputable sources like the SelfishNet GitHub repository.
