wlansvc service in Windows 7 can not be started

    Question

  • Hello,

    I have a problem with my wifi connection. I have discovered that the wlansvc service is not running but when I attempt to start this service, I get message: "Error 5: Access Denied". Other services, which are in wlansvc service dependency list, are running.

  • Hi,

     

    I suggest you copy the following files on another Windows 7 machine which WLAN AutoConfig service can start normally and import them to the problematic one.

     

    1. Locate the wlansvc.dll file under the folder C:\Windows\System32. Remove the old one and paste the new one.

     

    2. Navigate the following registry key on another Windows 7 machine and export it. Then, please copy and import it on the problematic machine.

     

    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Wlansvc

     

    If the issue persists after performing above suggestions, I suggest you run System File Checker (SFC) to verify whether any system file is corrupted.

     

    Thanks,

    Novak

  • Here is what I did to fix this problem.

    Windows System Restore

    One way to work around this error message is to use System Restore to set your computer back to previous settings before it encountered this problem. System Restore won’t delete any of your data, only change the configuration, however you will need to repeat any updates or any other changes you have made since the last Restore Point was saved.
