Tady jsem ti udelal rychlej ovladaci panel :

function WIFI_MENU
{
    param (
        [string]$Title = 'Wi-Fi control panel'
    )
    Clear-Host
    Write-Host "••••• $Title •••••" -ForegroundColor green 
    # Menu vyber
    Write-Host "[1] Volba '1' → Wi-Fi [ON]"
    Write-Host "[2] Volba '2' → Wi-Fi [OFF]."
    Write-Host "* Stiskni  'Q' pro ukonceni *" -ForegroundColor red
}
do
 {
     WIFI_MENU
     $selection = Read-Host "`r`n Vyberte volbu  "
     switch ($selection)
     {
         '1' {       
             Enable-NetAdapter -Name "Wi-Fi" -Confirm:$false    
              #WiFi zapnout
         } '2' {
             Disable-NetAdapter -Name "Wi-Fi" -Confirm:$false
              #WiFi vypnout
         }         
     }
     pause
 }
 until ($selection -eq 'q')

PS: V CMD vypisuje co ?
Kdyz se podivas v tom "Get-NetAdapter" tak by jsi ho mel videt aktivovany, jestli je vyply na HW urovni, musi byt povolen, treba pres spravce zarizeni nebo v "Control panel" → "Network" → pravy klik mysi : "ENABLE".
