This is the free demo of the paid Windows Automation Toolkit. It is the network diagnostics script, working, complete, no strings attached.

WHAT IT DOES

Run one command and it prints the four things you actually check when the internet misbehaves: network adapters with their real chipset names, the current Wi-Fi profile, the default route, and the DNS servers.

WHAT YOU NEED

Windows 10 or 11. PowerShell 5.1, which is bundled with Windows. No administrator rights. No installation.

HOW TO RUN

powershell -ExecutionPolicy Bypass -File .\diagnostika-seti.ps1

To keep the output to a file you can attach to a support ticket:

powershell -ExecutionPolicy Bypass -File .\diagnostika-seti.ps1 *> otchet.txt

WHAT IT IS A SAMPLE OF

The paid toolkit bundles four tested scripts: registry backup with rollback, this network diagnostics script, folder analysis, and a freelance order filter. Each one in the full version also ships with an instruction file covering how to read the output, a table of common errors, and a sample output from a real run.

ONE THING WORTH KNOWING IF YOU RUN IT

The first version of this script searched for your Wi-Fi adapter by the connection name looking for the word Wi-Fi. On a Russian Windows that field reads 'Wireless Network', so the script reported no adapters on a perfectly working network. It now searches the chipset name instead, which is not translated. This is mentioned because you will see the same class of problem in plenty of scripts sold online.

It only reads state and never changes anything, so it is safe to run on a machine that is not yours.
