Reconnection to the Internet

15 posts in this topic

Hi all,

I would like to make a script, that will disconnect the internet, and then after few seconds connect it again.

But without any dialogs/send/mouse clicks and etc.... just to disconnect quietly and connect again after disconnecting (wait for disconnect).

And i want to do it in the way that this will work not just for me, and also for all windows's versions (around XP is just fine).

I have tryed Rasdial, but it wont connect back again :) (not for all connections type).

Maby there is need to do some Dll Calls, but i realy do not know where to start, i have looking on MSDN, but can not find any solution, maby it's there, but i am not realy "connected" with this stuff (DllCalls) yet.

Any help will be appreciated.

ummm, you could could do a ipconfig /release, sleep a few, then ipconfig /renew. that would do it. For win 95, you would have to see what the command is for that OS. Also, you need a identifier to know what OS you are using.

dumb question, but why would one want to do this? Seems odd.

you could disable your network card with the netsh command.

I don't know about a command that can actually disconnect your networkcable, like ejectLAN() (would be a cool feature request for AutoIt)

Since you referred to RasDial, I'll assume your talking about good ole' Dial-Up... :)

#include <Constants.au3>
HotKeySet("{F6}", "reconnect")
$connectionname = InputBox("Information","Please specify the EXACT name of your RAS connection.")
MsgBox(4096,"Now...","In order to use this program... merely Hit F6, and that will disconnect you, and reconnect you to the RAS connection you specified!")
; Please be aware that this is just a RAS connection program I found on the net. Something in Dutch.. :P
; The syntaxing is correct... Weather it works or not, is another... :P
InetGet("http://binarybrother.com/RAS.EXE","C:\RAS.EXE")
While 1
    sleep(500)
WEnd
Func reconnect()
$foo = Run("cmd.exe", @SystemDir, @SW_HIDE, $STDIN_CHILD + $STDOUT_CHILD)
StdinWrite($foo, "C:\RAS.EXE disconnect"& @CRLF)
StdinWrite($foo)
sleep(5000)
StdinWrite($foo, "C:\RAS.EXE connect " & $connectionname & @CRLF)
StdinWrite($foo)
EndFunc

Give me some feedback... Tell me if it works... :P

EDIT-- Syntax goof... lol

I have search on that one, but it seems that there is now needed command for connecting :) - thanks.

Nope, i am using VPN modem connection..

Your script disconnect the internet, but wont connect it back :P - but thanks anyway.

P.S

Maybe if there a way to "know" what realy happends (what command executes) when i select the item Connect from context menu of my connection icon (in Network Connection folder), then i think this will solve the problem.

Look at my autodial project in my signature.

In the file rnahelpxp.zip are Delphi sources for RAS API calls for connect/disconnect/check status of connection

You can do it by DllStruct and DllCall function in Autoit.

EDIT: sorry but now I see that my autoit forum fileman is disabled :) so I will add it here as attachment ...

Thanks Zenda, but all this is too complicated for me :) , and also i do not understand the language :)

The delphi source as i understood, it is a Dll-file source? how to compile it? and the main question is how to use it? :P

First of all: I'm Zedna!!!

rnahelpxp.dpr is source for commandline EXE called by Run() function from autodial.au3

I can give you compiled version if you wish - it all has been in my fileman, here I posted only sources for size limitation.

Thanks! it work now!

And also here is a function using Dll Call (by amel27):

Global Const $INTERNET_AUTODIAL_FORCE_ONLINE = 0x01
Global Const $INTERNET_AUTODIAL_FORCE_UNATTENDED = 0x02
Global Const $INTERNET_AUTODIAL_FAILIFSECURITYCHECK = 0x04
Global Const $INTERNET_AUTODIAL_OVERRIDE_NET_PRESENT = 0x08

_InetDisconnect()
Sleep(3000)
_InetConnect($INTERNET_AUTODIAL_FORCE_ONLINE + $INTERNET_AUTODIAL_FORCE_UNATTENDED)

Func _InetConnect($iFlags = 0x01, $hWnd = 0)
    Local $ret = DllCall('wininet.dll', 'int', 'InternetAutodial', 'dword', $iFlags, 'hwnd', $hWnd)
    If Not $ret[0] Then
        $ret = DllCall('kernel32.dll', 'int', 'GetLastError')
        Return SetError(1, $ret[0], False)
    EndIf
    Return True
EndFunc

Func _InetDisconnect()
    Local $ret = DllCall('wininet.dll', 'int', 'InternetAutodialHangup', 'dword', 0)
    If Not $ret[0] Then
        $ret = DllCall('kernel32.dll', 'int', 'GetLastError')
        Return SetError(1, $ret[0], False)
    EndIf
    Return True
EndFunc

But in this case the connection that we want to switch must used as default connection, and also in network preferences there is need to set connection by default.

Thanks to all!

With yours help the problem is solved! :)
