Disable Wireless When Connected to LAN in XP and Vista

We are releasing a Windows XP and Vista program called BridgeChecker that extends the “Disable Upon Wired Connect” capability that is available for Broadcom wireless cards to any brand wireleless card when the ethernet interface is connected.

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 Settings

The settings screen can be accessed by right clicking on the WLAN Book “globe” icon in the task bar.

  1. Does this work with Windows 7 RC?

    Thank you.

  2. It hasn’t been tested with Windows 7….yet.

  3. Please reprogram as a service, so it works for Windows Vista without UAC prompts.

  4. I am trying to download bridgechecker.msi but the download link isn’t working.

    Is this application still available?

    Thanks,

    smooter

  5. Thank you SO much… I have desperately looking for a way to do just this. Its small, its fast, its perfect! Thanks a million wlanbook.com. I will be recommending this software to my associates!

    Alfie – Network Administrator

  6. I try to test it but I find some error about when connected to lan it disable wireless and loop to enable wireless many time. Please let me know why and how to solve this problem.

  7. You probably have other interfaces (vmware, vpn, etc) that are detected as wired interfaces

  8. Yes – this program works with Windows 7 RC1. I ran it on a Dell Inspiron 9300 with an Intel 2200 wireless NIC while connected via the Broadcom ethernet NIC.

  9. It works fine when i’m not connected to my work VPN. When my VPN interface is connected, I have the looping problem. I’m on a Cisco AnyConnect SSL VPN, but we also use the older cisco client for regular VPN access as well. Is there any way to fix the looping bug for specific interfaces like VPN ones?

  10. The plan is to add a whitelist feature and/or ability to detect virtual adapters in next version.

  11. Why not just make a pulldown of the ethernet adapter and the wifi adapter to use. No guessing, no surprise adapters… just adapter A is disabled when adapter B is connected, etc.

  12. Hi
    Is it possible to hide the systray icon or fix the settings as an administrator and not allow users to change them.

  13. Agree with isaac no need for whitelist just a drop down to choose card ‘a’ (lan) and card ‘b’ (wireless). You would then not need to have a whitelist or subsequent issues with VPN connections. Running as a service would be better also. (not for the reasons of UAC). just would be more tidier and easier to administer.

  14. Yep — next release is coming soon and will be a service and have card selection feature.

  15. Will it work with Windows 7 x32 and x64?

  16. Not sure about x64 but a user has confirmed operation on x32.

  17. Are there install switches that enable the settings during installation so I can send this out using SCCM as a silent install?

  18. the mdb file in the program files/bridgechecker directory stores the config. Send the msi file and then the customized mdb file.

  19. can this be used with 3G USB dongles? I need to disable the wired connection if a 3G network connection is detected.

  20. If the 3G USB dongle shows up as a “LAN or High Speed Internet” interface in Windows XP Network Connections it is supported in BridgeChecker v1.2. If the 3G device is a “Dial-up” interface in Network Connections then the plan is to support dial-up interfaces in next minor release (coming soon).

  21. Hi

    We are currently running a view tests with BridgeChecker.

    When we install the tool with domain admin rights, not all the cards in our notebooks are recognized.

    If we install it with local admin rights, all the cards in our notebook where found.

    The Notebooks that we are running the tests on, are a Fujitsu Siemens Lifebook E8410, a Lifeboook P7230 and a Lifebook P8020.

    We have the same effect with all types.

    What can we do, to fix this?

    Thank you in advance for your help

  22. The new version does not work on Windows 7 x64. It installed fine but when launching the app I receive an error stating “Microsoft.Jet.OLEDB.4.0″ provider is not registered on the local machine. I have read that this problem exists because there is no OLEDB.4.0 driver for x64. I believe that if you change your code from “Any CPU” to specify “x86″ that it will run in 32-bit mode and work. Currently “Any CPU” will run by default in 64-bit mode.

    Thanks

  23. This tool does not work under Win7 x64 (it requires Jet DB 4.0 – imho useless when you can’t even set exceptions like VMware or VPN interfaces, but no x64 version is available).
