BridgeChecker

BridgeChecker is a windows utility that can automatically disable/enable wireless interfaces. Whenever your computer is connected to an Ethernet port and the link state is good, the utility can automatically turns off the IEEE 802.11 wireless network interface. This conserves IP address allocation, reduces security risks, resolves dual interface routing issues, and prolongs battery life.

BridgeChecker was released on May 22, 2009 and has been well received by Windows users searching for a way to automatically enable/disable wireless interfaces when the LAN interface is connected.

BridgeChecker Update

Since the initial release we have been working on new features and improving the user interface. An updated version is almost ready for release and will some of the most requested features listed below.

• Whitelist adapters
• Admin password to change config
• Hide notification area icon (sometimes referred to as system tray icon)
• Custom NIC selection for automatic enable/disable feature
• Software will run as a service to bypass Windows Vista UAC issues
• Two modes of operation, BridgeChecker mode and OneNIC mode

BridgeChecker Mode and OneNIC Mode

The biggest change since the first release will be the ability to run the program in two modes, BridgeChecker mode and OneNIC mode.

BridgeChecker Mode - will operate just like the previous version but will allow the adapters to be selected from a drop down list and also allow adapters to be whitelisted.

OneNIC mode – will allow the user to select one network interface and all other interfaces will be disabled. The goal of this feature was to give users the ability to use any type of interface (EVDO, dialup, wireless, wired, etc) but only “OneNIC” will be enabled at a time. The user is free to change which interface they would like enabled at any time.

BridgeChecker Administration Enhancements

The program will include a password protected admin interface to control which interfaces are whiltelisted, which mode to operate in, and to hide/remove the system tray icon.

BridgeChecker License and Support

The first version of BridgeChecker will continue to be available as a free download for personal and commercial use. No official support or warranty will be provided other than the comment/feedback feature of this blog.

The new/updated version will also be a no cost download and free for personal use. For commercial users we will be updating the software license to allow for a limited number of installs at no cost and no support.

For large deployments a fee based licensing model that includes support for organizations that require it before they can install software on production systems will be made available.
