How can I check WIFI speed with iPerf?

How can I check WIFI speed with iPerf?


  1. Download the iperf utility.
  2. On the server that will be receiving data, open an elevated command window and run the following command: “iperf.exe –s –w 2m”.
  3. On the server that will be sending data, open an elevated command window and run the following command: “iperf –c x.x.x.x –w 2m –t 30s –i 1s”.

Can iPerf measure jitter?

iperf can be used to collect latency and bandwidth statistics for both TCP and UDP. It uses a client server model, where data can be analyzed from both ends. Among stats it can collect – throughput, jitter, and packet loss. This is basically a tool to measure overall link quality.

What is iPerf WIFI?

It is a cross-platform (windows, linux) tool which can provide standardized measurement results for any network (Wireline or Wireless). Iperf works with client and server functionality, and can create data streams to measure the throughput between the two network node in one or both directions.

How do I test network throughput?

Iperf3 is a free an open source command line tool for measuring network bandwidth & throughput in real time. It is based on the Iperf series software that performs active measurements to find the maximum attainable bandwidth. The Iperf3 can test the maximum bandwidth and throughput in IPv4 or IPv6 networks.

What is iPerf3 used for?

IPerf3 is built on a client-server model and measures maximum User Datagram Protocol, TCP and Stream Control Transmission Protocol throughput between client and server stations. It can also be used to measure LAN and wireless LAN throughput.

How do I monitor network latency?

Measure network latency with PING Ping is the simplest approach to test network latency from your computer. Ping is a standard latency test tool available on all operating systems. It measures the round trip time (RTT) between your PC and the target you specify (domain or IP address).

What does iPerf3 measure?

What is better than Iperf?

The best alternative is Speedtest by Ookla, which is free. Other great apps like iPerf3 are mtr, SmokePing, Packet Loss Test and JPerf.

How is WIFI throughput measured?

Open a browser (Safari, Chrome, Firefox, whatever). Go to and hit Go. This will check your download speed in mbps, or megabits per second. If Speedtest says you’re getting more than 50 megabits per second (Mbps), you’re doing pretty well.
