Use the DevCon tool to restart your wireless card device with batch processing

Recently, due to work needs, wrote a batch to restart the wireless network card.

First of all, say something about my idea:

1. Ping the Gateway (default option, Gateway is 192.168.1.1) two times, if successful, the batch finishes

2, if not successful, the second time, restart the wireless network card

in order to achieve the above purposes. I need a tool that allows you to enable, disable, restart, update, delete, and query a single device or set of devices in a DOS command. And DevCon is just the tool for doing these things in Windows. It is not integrated in the Windows default installation, so we need to download the tool via our website or other websites. Since the official tool is not working properly in Win7 64bit, I recommend downloading to the following website:

http://download.csdn.net/detail/zhangzxing/5691253

Download the good files and unzip them. DevCon in 3 files: AMD64, i386, ia64. Copy the version of the operating system to the System32 directory of the system disk. According to the idea, write the batch process:

@echo off

for/f%%y in (' DevCon find usb\* ^|find ' MER ') do set wlid= "@%%y"

:: Crawl the hardware ID of the wireless card, I'm using mercury, so look for the "MER" included.

:: The quotation marks are added to the%%y to assign values as a whole string of%%y values. Otherwise the variable assignment will be intercepted

:: Because the value in%%y is recognized by DOS as a system path, it may contain a special symbol &

:: The reason for adding @ is because of this, the string as a whole to execute

:: Because the DevCon program corresponds to the execution mode, DevCon restart "@ Hardware ID", so the wlid variable value just matches the condition

set/p targie=<c:\ip.txt:: Enter the IP address from the file

For%%i in (on) do (:: Loop

Ping-w 1%targie% >c:\123.txt:: Network test

If%errorlevel%==0 (

:: Determines whether the ERRORLEVEL variable records the status of the last program execution, 0 is successful, and the other is failed

echo "%date%:%targie% is comneted!" :: The program executes successfully, then the output date and success information

) Else (
If%%i==2 (
echo "NETWORK SERVICE restarting ..."
DevCon restart%wlid%:: If the ping is unsuccessful and has been done two times, restart the NIC

If%errorlevel%==0 (
echo "NETWORK SERVICE is restarted!"
) Else (

echo "Network SERVICE restart Fail":: Determine the success of the NIC restart, and the corresponding prompt

) Else (
Echo Trying%%i time to comnetting%targie%:: If the ping is unsuccessful, the. Prompt is attempting to connect to Gateway 1, 2 times
)

)
)

Problems that arise:

After the ping, DevCon command executes, sometimes the value returned by the%errorlevel% error occurs.

This issue is not resolved. Still looking for a better way to judge.
