wlan-reconnect.ps1

wlan-reconnect.ps is a PowerShell script that uses the cmdlet text-connection to regularly check the WLAN connection and tries to reconnect with netsh wlan if it is gone.

If executed without parameter, it tries to connect to the SID named oooOOOooo. If executed with a parameter, the parameter is expected to be the name of the SID that the scripts should connect to:

The -speak flag can be specifed so that the script uses the Microsoft Speech Object Library to notify a change in the connection status:

Script

param (
  [string] $ssid  = 'oooOOOooo',
  [switch] $speak
)

set-strictMode -version latest

#if ($args.count -lt 1) {
#  $ssid = 'oooOOOooo'
#}
#else {
#  $ssid = $args[0]
#}

if ($speak) {
   $sapi = new-object -comObject sapi.spVoice
   $lastStatus = '?'
}

$host.ui.rawUi.windowTitle = "wlan reconnect $ssid"


while ($true) {
   $now = get-date -format 'HH:mm:ss'

   if (! (test-connection 8.8.8.8 -errorAction continue -count 1 -quiet) ) {
     "$now NOK"
      $null = netsh wlan connect $ssid

      if ($speak -and $lastStatus -ne 'NOK') {
         $null = $sapi.speak('connection down')
         $lastStatus = 'NOK'
      }
      start-sleep 1
   }
   else {
     "$now OK"

      if ($speak -and $lastStatus -ne 'OK') {
         $null = $sapi.speak('connection up')
         $lastStatus = 'OK'
      }
      start-sleep 15
   }

}
