Description

NetConnectChoose is a simple tool that allows you to easily choose the default Internet connection that will be used by all Internet applications, when you have more than a single Internet connection on the same time. (Each connection on different network adapter)
It also displays extensive information about every active network/Internet connection, including network adapter name, MAC Address, Name Servers, MTU, Interface Speed, current incoming/outgoing data speed, number of received/sent packets, received/sent bytes, and more...

System Requirements

This utility works on any version of Windows operating system, starting from Windows 2000 and up to Windows 11. Both 32-bit and 64-bit systems are supported.
On Windows Vista/7/8 with UAC turned on, you have to run NetConnectChoose as admin in order to smoothly change the default Internet connection. If you don't execute NetConnectChoose as admin, you'll get a confirmation UAC message-box for every default connection change.

Known Issues

On Windows XP, when changing the default Internet connection, all existing TCP connections stop working. On Windows Vista/7/8, when switching to another default Internet connection, the existing TCP connections remain active. This means that on Windows Vista/7/8, you can start downloading from one Internet connection and then switch to the second Internet connection, and start another download on the second Internet connection without interrupting the first download process, but it's impossible to do that on Windows XP.

Start Using NetConnectChoose

NetConnectChoose doesn't require any installation process or additional dll files. In order to start using it, simply run the executable file - NetConnectChoose.exe
After running it, the main window displays the details of all active network/internet connections. In order to change the default Internet connection, you can select the desired connection and press F8 (Set As Default Connection) or you can simply press F9 to switch between the active connections.

Packets Information

NetConnectChoose displays packets information for every active network connection on your system. The packets information include the total number of received bytes, total number of sent bytes, total number of received packets, total number of sent packets, current sent data speed, and current received data speed.
The packet counters are saved to the .cfg file, so in the next time that you run NetConnectChoose, it'll start with the number you had when you closed NetConnectChoose previously. You can reset the packets information to 0, by using the 'Reset Packet Counters' option.

Command-Line Options

/SetDefault <MAC Address>	Set the specified network adapter as the default Internet connection. On Windows Vista/7/8 with UAC turned on, you must execute this command with 'Run As Administrator'. Example: NetConnectChoose.exe /SetDefault 00-21-AD-C2-36-A0
/SwitchDefault	Set the next network adapter as the default Internet connection. You can use this command to easily switch between 2 or more Internet connection. On Windows Vista/7/8 with UAC turned on, you must execute this command with 'Run As Administrator'.
