Network Tool

Overview

Network Tool is an application designed to measure network speed and performance between hosts in a Local Area Network (LAN). The tool includes features such as running an iperf server, performing ping tests, and more. This README provides essential information on setting up, running, and using the application.

Use-cases

• Your wifi network is slow at some places and you want to figure out the deadspots by walking around with your laptop.
• Your video call sometimes stutters but you don't know if it's related to your network.
• You doubt if your router can handle the traffic now you upgraded to a higher speed.
• You wonder if your ISP delivers a stable througput
• Your online game sometime stutters, but why?

Features

• Iperf Server: Runs an iperf server to measure network speed between two hosts in the LAN.
• Ookla Speedtest: Performs a speed test using Ookla Speedtest to measure network speed.
• Ping Tests: Performs ping tests to measure latency and packet loss.
• Graphical Visualization: Provides graphical visualization of network statistics.
• Background Polling: Monitors network interfaces and SSID changes in the background.
• Data Export: Allows exporting the network statistics to CSV files.
• Audible status: A tone can be played to help the user sense the networks state without looking at the screen. The frequency of the tone indicates the state. This allows the user to walk around with the laptop to find dead spots or to tweak the network settings without having to constantly check the screen.

minor features:

• Mouse zoom and pan on the charts.
• Autoranging on the charts
• Linked time axes between the latency and bandwith charts
• Numerical statistics with min, avg, max

Using the Iperf Server

To measure network speed between two hosts in the LAN:

1. Install NetworkTool on both hosts in the LAN.
2. Start the iperf server on host A from the windows menu or by running iperf -s.
3. On host B, use the 'Start Iperf' feature in the application to measure network speed.
