6 Best Free LAN Speed Test Software For Windows

Here is a list of best free LAN speed test software for Windows. Using these software, you can easily determine the speed of your local network at any given movement. Along with the speed of wired LAN, you can also determine the speed of wireless LAN through these software. Most of these LAN speed testers form a client and a server computer and then transfer data between them to determine speed. However, to form client and server, you need to have same LAN speed tester software in both computers which are being used for LAN speed testing. There are also some software which can test LAN speed only by using a single computer. However, in them, you need to provide IP address along with the path of a shared folder of another computer to test LAN speed.

After completion of tests, you can view various resultant values like Effective bandwidth of LAN, Average LAN speed, Maximum LAN speed, Time to send the packets, etc. In some software, you will also be able to save speed test result as TXT, CSV, PSD, etc. files.

My Favorite LAN Speed Test Software For Windows:

LAN Speed Test is my favorite software because it can perform both quick and exhaustive LAN speed test. It lets you manually set the size of data packets between 2KB (for quick testing) to 9GB (for exhausting testing). Plus, the final result provided by it is also very detailed that you can also save as PDF.

NetIO



NetIO-GUI is a free, portable, and open source LAN speed test software For Windows. Using this software, you can test speed of your local area network and Ping Roundtrip time using either TCP or UDP protocol. To test LAN speed, this software sends and receives multiple data packets of different sizes between two computers of the same network. Once the speed test gets completed, it shows you packet transfer and packet receive speeds. Plus, Ping Round Trip time is also shown by it on the main interface.

In order to test LAN speed, you need have one server computer and one client computer on a network. To do that, you need to first install this software on both computers which are connected through same LAN. After that, select the Server Mode in one system and press the Start Server button to make it a server. In the other system, select Client mode and provide the IP address of server computer in the IP Address Field. At this time, you can also select a Protocol (TCP or UDP) before starting the LAN speed test. After setting up all the configurations, just press the Start Measure button to start the testing. You get both the Ping Roundtrip time along with Packet receive and send speed over the LAN network in the real time. You can save the obtained result as Excel/CSV and as a Text file. By default, this software provides LAN speed result in Kb/sec, but you easily can change it to b/sec, Mb/sec, or Gb/sec. Overall, it is another simple software to test LAN speed.

SpeedConnect Connection Tester



SpeedConnect Connection Tester is the next free LAN speed test software for Windows. This software allows you to quickly test both the Internet and LAN speed. Plus, the process of testing the LAN and internet speed is also quite similar. In case of Internet speed test, you need to provide URL of a test server after which you can start the internet speed test. Similar to this, for LAN speed test, you also need to provide the path of the test server but instead of an online server, you need to provide the path of a local network system. The path of local server consists of IP address of the server computer along with the path of a file or folder contained in the shared folder. The path would look similar to this: \\192.168.11.123\LISTOFFREEWARE\testfile.zip. After entering the path, press the Run New Test Button to start LAN speed test. After the test, you can view LAN speed in kbps, Duration of the test, File Size, Latency, LAN Quality, etc. from its interface.

In it, you also get two more handy features namely Internet Accelerator (to speed up the downloading and overall internet speed) and Network Monitor (a small on-screen internet monitor to show the real-time upload and download speeds).

Note: Some features of this free software is locked. By purchasing its paid version, you can use all of its features.

iPerf



iPerf is a free and portable command line based LAN speed test software for Windows. Using it, you can measure maximum achievable bandwidth over a LAN or IP network. Plus, it also allows you to tune various parameters related to Timing, Buffers, and Protocols (TCP, UDP, SCTP, etc.). In order to perform parameters tuning or LAN speed testing, you need to know various commands as it does not have any interface. To view all supported commands, launch this software in Command Prompt and enter iperf.exe and press Enter.

How to test LAN speed using commands:

  • First, you need to create a server on a system other than yours over the same network. To create a server, launch this software using the command line and write command iperf -s to start the server.
  • Now, return to your system and enter iperf -c  space server IP to start LAN speed test.
  • During the test, you can view size of transferred packet size along with the maximum bandwidth obtained or LAN speed (Mbits/sec) in real time.

After completion of the test, you can view time interval to test LAN speed, total number of transferred data to test speed, and average bandwidth or LAN speed over the command line. Apart from LAN speed test, you can also use this software to test disk read and write speeds.
