Hi. My name is***** you for your question and the opportunity to assist.

Is there and numeric error code associated with the service not starting?

Ask Your Own Computer Question
Customer reply replied 1 year ago
error code 126. was previously giving an error code 193 but switched to 126 after performing chkdsk and sfc
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

Thanks is it the WLAN AutoConfig service that's not starting?

Ask Your Own Computer Question
Customer reply replied 1 year ago
that's correct. I tried to replace the wlansvc.dll with a known functional version, but when I try to take ownership (takeown from the command prompt), i get a message that the system cannot find the file specified. but it's definitely in the folder and shows if i type 'dir'
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

Thanks. Have you tried uninstalling the wi-fi adapter in Device Manager and restarting the computer?

Ask Your Own Computer Question
Customer reply replied 1 year ago
i did a full network reset a while ago, which I believe uninstalled the wi-fi adapter, if i'm not mistaken.
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

Is this a Windows 10 machine?

Ask Your Own Computer Question
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

Right-click the start menu button and open Device Manager. Expand Network Adapters. Right-click the wi-fi adapter and Uninstall

Close Device Manager and right-click the start button again and select Command Prompt(Admin)

At the blinking prompt enter the following commands, pressing Enter after each

netsh winsock reset

netsh int ipv4 reset

netsh int ipv6 reset

Restart the machine and check

when I uninstall, should I check the box for 'delete the driver software'?
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

No. Leave that unchecked.

Ask Your Own Computer Question
Customer reply replied 1 year ago
about to restart, but before I do wanted to note that for both ipv4 and ipv6, after "Resetting path, OK!", it says "Resetting , Failed. Access is denied"
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

I know but at the end it says Resetting OK

right. restarted - i'm back.
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

So, no success? If you've replaced files I'd run sfc /scannow again to get the right ones put back.

Customer reply replied 1 year ago
i haven't replaced any files, that i know of
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

You mentioned you, I guess, tried to replace a dll.

Click the start button and open settings. Open Update & Security

click Update History

click Uninstall Updates

Can you find the ones that were installed?

Ask Your Own Computer Question
Customer reply replied 1 year ago
i tried to replace the wlansvc.dll but I couldn't even take ownership of it. I've got updates that were installed on 9/29, 10/3, 10/11, and today (10/18)
Customer reply replied 1 year ago
i'm a little concerned that my wireless adapter isn't in the device manager anymore...
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

Windows should have re-installed it when the computer restarted.

Open Device Manager. At the top of the list you'll see your computer name.

Right-click on it and select Scan for hardware changes.

Can you get the laptop connected to the internet via ethernet cable connected to your router?

Ask Your Own Computer Question
Customer reply replied 1 year ago
actually it is there, but now it says 'network controller' instead of 'intel dual-band wireless' or something to that effect
Customer reply replied 1 year ago
i am connected via ethernet on this laptop
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

It needs a driver. I think the update hosed it.

Right-click the network controller and select Properties.

What does it say in the status window?

Ask Your Own Computer Question
Customer reply replied 1 year ago
says 'this device is working properly'
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

If it was working properly it would list the wi-fi adapter by manufacturer.

What's the model number of the laptop?

Customer reply replied 1 year ago
btw when i run sfc, i get a report saying that windows resource protection found corrupt files but was unable to fix them. when I check the log, it's the wlansvc.dll file
Customer reply replied 1 year ago
that's why I wanted to replace the .dll file, but I wasn't able to because I wasn't able to take ownership of it in order to replace it
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

Ok. Since you have an internet connection do this:

right-click the taskbar and start task manager.

Click More details if you see it.

click File>>Run new task

put a checkmark in the administrative checkbox and in the text area type: powershell and click OK

At the blinking prompt in the blue window copy and paste the following command and press Enter

DISM /Online /Cleanup-Image /RestoreHealth

After pressing Enter it will sit there for several minutes looking like it isnt doing anything, but it is.

Then it will jump to 20% and sit a bit longer and finally finish. Restart the computer when it finishes.

Ask Your Own Computer Question
Customer reply replied 1 year ago
haven't restarted yet, but at the end it gave an error:Image Version: 10.0.14393.0[==========================100.0%==========================]
Error: 0x800f081fThe source files could not be found.

Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

That should work if you're connected to the internet.

Can you try it again.

Ask Your Own Computer Question
Customer reply replied 1 year ago
ok re-ran the powershell. this time it's at 100% and no error showing. Yes - my laptop is the 20A7
Customer reply replied 1 year ago
spoke too soon. same error as before showed up
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

Well, I was hoping the image would get repaired and you'd be able to fix the dll with sfc.

On the Lenovo page where it says Pick a Component, set it to Wireless LAN

You'll see the driver listed for your wi-fi adapter. You probably have 64 bit Windows

but you can confirm that by right-clicking the start button and opening System.

Install the driver. I don't know if it will put back the correct dll though.

Ask Your Own Computer Question
Customer reply replied 1 year ago
done. same situation
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

Are you opening services.msc from the run box and trying to start WLAN AutoConfig from there?

Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

Thanks. I'm out of ideas on this. I'll open your question up to all the category experts. One of them

may have an idea how to get this service started.

There's one thing I didn't propose. You could do a reset of Windows 10 using the Keep my Files option.

It would mean re-installing software programs, though.

Ask Your Own Computer Question
Customer reply replied 1 year ago
Thanks, ***** ***** already knew that option...that was my last resort and I was trying to avoid it.
Customer reply replied 1 year ago
Also, I never saw any response from anyone else
Tech Support Specialist: Byron, Computer Support Specialist replied 1 year ago

Another expert isn't required to respond. I'm thinking that they may have read the conversation and decided not to.

You can try this though, go here: https://www.microsoft.com/en-us/software-download/windows10/

Download the media creation tool. When you run it select the option to create media

for another PC. Use a 4+GB flash drive and create the install disk. Open the flash drive

from within Windows and run the setup.exe file and install Win 10 on top of itself.

I found an article on it but you probably don't need it.

I am very happy with my very fast response. Eric is very knowledgeable in the subject area. Thank you!

RPAustin, TX

Hi John, Thank you for your expertise and, more important, for your kindness because they make me, almost, look forward to my next computer problem. After the next problem comes, I'll be delighted to correspond again with you. I'm told that I excel at programing. But system administration has never been one of my talents. So it's great to have an expert to rely on when the computer decides to stump me. God bless, Bill
