Automate internet connection + failsafe

[mas81 0]

Hello,

I have been looking for something to do the below scenario and searched through the forum but all what I have found are scripts that only do one part of the scenario:

PC have 3 ways to connect to the internet:

1- GRPS modem (which connect useing a dial up connection)

2- USB Modem (which connect useing a dial up connection)

3- LAN ( which is disabled)

When you start the PC the script will be in the windows start up and the following will happen:

1- Dial GRPS connection

2- Launch an application

3- Check connection every 5 minutes through ping / IP address or URL

4- If the connection is up the script will sleep for another 5 minutes then repeat step 3 and keep doing this in a loop

5- If the connection is down the script will disconnect the previous dial up connection and dial USB modem connection

6- Repeat step 3

7- If the connection is down the script will disconnect the previous dial up connection and enable the LAN connection

8- Repeat step 3

9- If the connection is down the script will disable lan connection and dial GPRS connection

10- Repeat step 3

I'm not a programmer but I have found a script here in the forum and tried to make it do the above scenario but with no luck, below is what I have done:

; put the compiled EXE (or a reference to it) in the startup folder.
#NoTrayIcon   ; disable tray icon. So, no accidential pause can occour
Sleep(300000) ; allow 5 minutes boot time.
While 1 ; never ending loop
Ping("google.com") ; try to reach google.
    If @error Then
        Ping("de.pool.ntp.org", 2000) ; try to reach a time server.
    If @error Then
     Run("netsh interface set interface ""Local Area Connection"" DISABLE")
     Run, %COMSPEC% /C rasdial con1,Hide
    EndIf
Sleep(300000) ;
Ping("google.com") ; try to reach google.
    If @error Then
     Ping("de.pool.ntp.org", 2000) ; try to reach a time server.
    If @error Then
     rasdial /disconnect
     Run, %COMSPEC% /C rasdial con2,Hide
    EndIf
Sleep(300000) ;
Ping("google.com") ; try to reach google.
    If @error Then
     Ping("de.pool.ntp.org", 2000) ; try to reach a time server.
    If @error Then
     rasdial /disconnect
     Run("netsh.exe interface set interface ""Local Area Connection"" ENABLE")
    EndIf
    EndIf
WEnd ; merry go round
