In the Windows environment, managing and troubleshooting network connections is a critical task for systems engineers. While there is no direct Get-NetWiFiNetwork command in Windows PowerShell, you can achieve similar functionality using available cmdlets and commands. This article will guide you through the process of discovering available Wi-Fi networks using PowerShell, which is an essential skill for network management and troubleshooting.

Examples:

1. Using netsh wlan Command: Windows provides a built-in command-line utility called netsh that can be used to manage network configurations. The netsh wlan command can display a list of available Wi-Fi networks.

   netsh wlan show networks

   This command provides detailed information about all visible Wi-Fi networks, including their SSID, signal strength, and security settings.

2. Using PowerShell to Parse netsh wlan Output: You can also use PowerShell to run the netsh wlan show networks command and parse its output for more structured data handling.

   $networks = netsh wlan show networks | Select-String "SSID" -Context 0,1
   $networks | ForEach-Object {
      $ssid = $_.Line.Split(":")[1].Trim()
      $signal = ($_.Context.PostContext[0] -split ":")[1].Trim()
      [PSCustomObject]@{
          SSID = $ssid
          Signal = $signal
      }
   }

   This script captures the SSID and signal strength of each network and outputs them as custom PowerShell objects.

3. Using Wi-Fi Adapter Information: To get more detailed information about your Wi-Fi adapter and the networks it can see, you can use the Get-NetAdapter and Get-NetAdapterStatistics cmdlets.

   Get-NetAdapter -Name "Wi-Fi" | Get-NetAdapterStatistics

   This command provides statistics and information about the Wi-Fi adapter named "Wi-Fi".
