    Hi,


    Having a WLAN problem with our Dell XPS 15 Z running Windows 7 Home Premium.

    When I click on the network connections icon in the task bar, it lists only Dial-up and VPN, but gives no WiFi options. This problem started several months ago but I’ve ignored it until now. The problem is not our router, as I am currently connected to our wifi network using on another laptop. The problem laptop is able to connect to the internet through the router with an ethernet cable. If I go to Network Connections in the control panel, it lists “Wireless Network Connection” (and indicates the hardware is Intel Centrino Advanced –N 6230).

    Here are things I’ve tried to do so far (none of which has resolved the problem) :



    - Ran MalwareBytes and AVG – no problems found.

    - Disable and re-enable the Wireless Network Connection. Result: no change

    - Diagnose the Wireless Network Connection. Result: “Problems found, the Windows wireless service is not running on this computer, Not fixed.”

    - In Device Manager: checked the Intel adapter - says it is working properly. Tried updating the driver – says it’s the most up to date driver.

    - Ran netsh winsock reset, int ipv4 reset, and int ipv6 reset and restarted the computer. Result: no change

    - System restore. Looked into it but didn’t do it because all the saved restore points are after the problem started.

    - Ran services.msc and tried to start the WLAN AutoConfig. Result: Error 1747 The authentivation service is unknown.

    - Ran the System File Checker tool. Result: “…found corrupt files but was unable to fix some of them”. Checking the log, I searched for “cannot repair” but nothing comes up. Searching for “cannot” in the logs turns up some cases of “cannot verify component files for Microsoft-Windows-Security-Kerberos…”. Search for “corrupt” turns up nothing.

    - Tried the things listed here http://www.justanswer.com/software/7fr8d-hello-again-molinari-i-question-you.html For the first set of suggestions - the “start” entries in the Ndisuio folders were already at 3. Deleted text as instructed in "DependOnService" and “EapHost" and restarted the computer. Result: no change.


    - For the second set of suggestions on that page (making changes to specific services in services.msc), I got the same exact results as that person, except that this fixed their problem but not mine. Notably, I could not find “Native wifi filter” or “NDIS usermode io protocol”, and for “Remote Access Auto Connection Manager” and “Remote Access Connection Manager” I get Error 1068 (The dependency service or group failed to start”. I then tried to start “Secure Socket Tunneling Protocol Service” as suggested. It says it “…started then stopped. Some services stop automatically if not in use by other services or programs”.


    That's what I've tried.


    I see that “Native wifi filter” or “NDIS usermode io protocol” are listed in the dependencies for the WLAN AutoConfig, and these 2 services are not showing up in my services list. Any chance this is part of the problem? If so, how do I resolve that? Any other suggestions?



    Thanks in advance!

    so these seem to be the two issues
    if windows files are corrupt - may need to re-install windows

    Dell also has a wireless manager
    is this running
    http://support.dell.com/support/edocs/network/p70008/EN/utility.htm

    WLAN AutoConfig
    right click on the service
    then from the menu choose properties and now check the dependencies.

    for each dependency entry - Check each of one of the dependencies and see which one is preventing the service from running/starting.

    Thanks for the very quick reply.

    The Dell Wireless Utility does not seem to be running, or installed for that matter.

    As for the WLAN AutoConfig dependencies, the Extensible Authentication Protocol and Remote Procedure Call both seem to be running, but neither the Native Wifi Fillter nor the NDIS Usermode I/O Protocol can be found in the services list.

    To verify that the dependency components are running. Follow the steps below:
    • Click Start, Run and type DEVMGMT.MSC
    • In the View menu, click Show hidden devices
    • Double-click Non-Plug and Play drivers section
    • Double-click the entry Native Wifi Fillter" and click the Driver tab
    Whats the startup type set to ?
    • Start the service. Note down the error message if any.

    Similarly start the other driver namely:

    NDIS Usermode I/O Protocol

    Post back if all are started and any error messages

    • Now check if you can start the DHCP client service.

    also run fabar and post the log

    Yes, as far as I can tell the dependencies are indeed working and running. The fixit you recommended is for XP and Vista - will it also work on my Windows 7 system?

    It seems it's also the fix for Windows 7. Ran it and restarted the system - everything is still the same. Still no Wifi in the Network Connections and still error 1747 in WLAN AutoConfig

    Winsock and ipv6 resets went okay. the ipv4 now says "There's no user specified settings to be reset." Don't remember getting this message when I ran these resets yesterday...think it said the same as the others still do ("Reseting Interface, OK! Restart the computer to complete this action.")

    Anyway, restarted and everything still the same.
