PingTool: LAN Speed Test Tool Windows 11    29-Nov-2025

You can use the free Speedtest tool to perform internal network speed tests in your LAN easily. Copy operations are performed within a few seconds and the bandwidth in Mbps (megabits per second) is determined for the send and receive direction - also for VPN connections. You can define up to three speedtest destinations, which you can select via the drop-down field. These can be UNC paths or paths with drive letters. The results are recorded in a history for documentation and comparison purposes. The Speedtest tool is - like PingTool - free and portable.



The LAN Speedtest tool allows the network administrator or ServiceDesk agent to determine the LAN network bandwidth on the fly. The bandwidth is also very interesting when working remotely via VPN, as often only low values are achieved here and work can suffer as a result. Of course, this value can also be determined with the Speetest tool.

Integrated Speedtest tool
The speedtest has been integrated into PingTool since PingTool version 4.2 and no longer needs to be downloaded separately. Simply click on the "Speedtest" button to start it:



Set up the speedtest destination
The speed test is carried out between your computer and a network folder that you can freely choose. To ensure that the test runs correctly and produces reliable results, the following requirements must be met by the selected destination:

• Read and write permission
• Speedtest files must exist

Proceed as follows to set up a speedtest destination:

1. Use a network folder to which you have read and write permissions or create a new one. This can be a UNC path (example: \\Fileserver1\Data\Speedtest) or a path with a drive letter (example: O:\Speedtest).
2. Enter this path in the Speedtest tool under "Speedtest destination". Click on "Start". A window appears that checks the remote directory. The first two checks should show a green tick and the third a red X. Now click on "Create files now".
3. Click on "Repeat check". All three checks should now show a green tick. Close the window and perform a speed test.

Enter fixed speedtest destinations
There are two ways to enter a fixed speedtest destination so that it can be selected from the drop-down field:

Option 1: Pass the speedtest destinations as arguments when calling the Speedtest.exe file. Use the following syntax:

Speedtest.exe -language:<english|german> -remotepath1:<path1> -remotepath2:<path2> -remotepath3:<path3>

Example:
Speedtest.exe -language:english -remotepath1:\\FS-NewYork\Speedtest$ -remotepath2:\\FS-London\Data\Speedtest -remotepath3:o:\it\speedtest

Put the path in quotation marks if it contains spaces.

Option 2: Enter the speedtest destinations in the PingTool.ini file. The file is located in the same directory as the Speedtest.exe file. Use the following syntax:

RemotePath1=<path1>
RemotePath2=<path2>
RemotePath3=<path3>

Example:
RemotePath1=\\FS-NewYork\Speedtest$
RemotePath2=\\FS-London\Data\Speedtest
RemotePath3=o:\it\speedtest

If both options are used at the same time, the option with arguments has the higher priority.
 

Check speedtest destination
Via the 3-dot menu and "Check speedtest destination..." you have the option of checking the currently selected speedtest destination for functionality. The speedtest destination should contain 4 files with the sizes 1MB, 5MB, 32MB and 128MB. At least the two files with the size 1MB and 5MB must exist so that the speed test can be performed. If you are expecting results above 10 Mbps, the two large files (32 and 128MB) should also exist to ensure an accurate measurement result.

Scheduled speed tests
Since version 4.3 you are able to run scheduled speed test, e.g. "every 5 minutes". This allows you to carry out a longer measurement over hours or days.
 

Start speed test from network drive
Just like PingTool itself, the Speedtest tool can be started directly from a network drive and does not require any installation. Simply copy all the files from the download into a network folder and start speedtest.exe.

 

FAQ

► Do I also need a speedtest server to perform LAN speed tests?

No. You only need a remote network share or a network drive letter as destination.

► Can I run the speedtest tool without PingTool?

Yes. Just double-click on the Speedtest.exe file.

► How much does the Speedtest tool cost?

Speedtest tool is free of charge. It is a part of PingTool.

1,000 Mbps - Gigabit Ethernet (standard wired PC speed)
10,000 Mbps - TenGigabit Ethernet (server default)
25,000 Mbps - 25G Ethernet
40,000 Mbps - 40G Ethernet
100,000 Mbps - 100G Ethernet
