Batch files for changing network-adapter settings in windows 7
by Prabhat Rai

Every day I (and I guess most of us) face an issue regarding the adapter setting change. For office, we have a dedicated IP and settings, so change the settings, then as soon as I go home I need to connect to my home Wi-Fi and that need automatic IP and DNS settings, so again change the settings to default. Previously I was  on Ubuntu so I never cared about this as Ubuntu handles this very efficiently. But in Windows go to network settings then adapter settings blah blah blah. So here I will show to create 2 files that is office.bat and default.bat for doing it easily on windows 7. These files changes the settings as soon as you run these files.

 :: Configuration Variables ::

 set connectionName="Wireless Network Connection"

 set ipAddress=x.x.x.x

 set subnetMask=x.x.x.x

 set defaultGateway=x.x.x.x

 set primaryDNS=x.x.x.x

 set alternateDNS=x.x.x.x

 netsh interface ipv4 set address name=%connectionName% source=static addr=%ipAddress% mask=%subnetMask% gateway=%defaultGateway%

 netsh interface ipv4 set dns %connectionName% static %primaryDNS%

 netsh interface ipv4 add dns %connectionName% %alternateDNS% index=2

The content in these batch files is self explanatory

change the following

    connectionName -> The name of the connection you want to modify

Replace x.x.x.x of the variables with the following

    ipAddress-> your IP

    subnetMask-> subnet mask

    defaultGateway-> Default Gateway

    primaryDNS-> Preferred DNS server

    alternateDNS -> Alternate DNS server

save the file as office.bat, right click on the file and select “Run as Adminisrator” [If security warning comes up click OK] and your settings are changed to STPI.

For default the content of the batch file will be a little different

 :: Configuration Variable ::

 set connectionName="Wireless Network Connection"



 netsh interface ip set address %connectionName% dhcp

 netsh interface ip set dns %connectionName% dhcp

DHCP means Dynamic Host Configuration Protocol.

With DHCP, computers request IP addresses and networking parameters automatically from a DHCP server, reducing the need for a network administrator or a user to configure these settings manually. [From Wikipidea]

 :: Configuration Variable ::

 set connectionName="Wireless Network Connection"



 :: Disable ::

 netsh interface set interface %connectionName% DISABLED



 :: Enable ::

 netsh interface set interface %connectionName% ENABLED
