Win 10 - WLAN AutoConfig stops continually - wireless problems

Question

Win 10 - WLAN AutoConfig stops continually - wireless problems

After installing Windows 10 via BootCamp (tried two ways, details below) on my iMac 27" Late 2013, I cannot keep a wireless connection. A bit of research pointed me to a service called WLAN AutoConfig which is not set to start automatically by default. So, I went into Services, found WLAN AutoConfig, set it to auto-start, and continued having the problems.

Every time wireless goes out, WLAN AutoConfig is stopped. I have gone into the properties of the service and modified settings in the Recovery tab telling it to Restart the Service after all failures ("Subsequent failures") after 0 minutes. That takes care of getting the service started, but Win 10 still won't rejoin my wireless network automatically (even though I have the box set telling it to via the system tray).

Net result: my wireless fails on me every 5-10 minutes, and frankly I'd just go out and buy a mid-range PC desktop were it not for the fact that other Windows users are reporting the same symptoms.

Any ideas or suggestions? More details are below.

Additional details:

1. Nothing shows to be wrong in device manager.

2. Broadcom 802.11ac Network Adapter driver is up to date (installed with bootcamp, and told it to update manually).

3. All dependent services to WLAN AutoConfig are also set to auto-start.

4. To the extent that I know how to interpret what I see in Event Viewer, I don't see anything indicating why the service stopped.

5. This is not a BootCamp problem specifically... there is this thread (http://answers.microsoft.com/en-us/windows/forum/windows_10-networking/wlan-serv ice-stops-under-windows-10/f7862b10-e370…) showing that various Win 10 users on non-Mac hardware are having problems too.

6. This happened after an update from Win 7 from within Windows, as well as a complete clean erase/install of Windows 10 Home 64-bit.

7. I did not notice the problem until Windows Update installed "Update for Windows 10 Version 1511 for x64-based Systems (KB3122947)" and "Security Update for Internet Explorer Flash Player for Windows 10 Version 1511 for x64-based Systems (KB3103688)". Although admittedly, I did not spend much time using the system last night before these updates installed.

Thanks for any help you can give. No Windows, No Gaming. No Gaming, Sad Jeff.

iMac (27-inch, Late 2013), Windows 10

Is the Broadcom adapter using the Apple BC driver or a W10 WHQL driver?

Not an expert Windows guy, but here's what I see:

Device Manager > Network Adapters > Broadcom 802.11ac Network Adapter Properties > Driver

Driver Provider: Broadcom, 7/24/2015 7.35.118.40 signed by Microsoft.

Also, worth noting: Win10 installed 3 updates overnight. Two are mentioned above and there was one other in the uninstall list. I uninstalled them all, and I haven't disconnected once since. (Packets: Sent = 3398, Received = 3398, Lost = 0 (0% loss),)

So, I'm tentatively leaning towards a bug in one of the updates. Any thoughts?

Can you uninstall the current driver, remove the device, install the BC driver and then reboot and test?

Loner: That is the driver, I presume, that installed with Boot Camp software. If you can point me to the installer for what you believe to be the Boot Camp version, I can give it a go.

For the iMac 14,2 (your model) the version of BC drivers should be

<ProductManufacturer>Apple Inc.</ProductManufacturer>

<ProductVersion>6.0.6133</ProductVersion>

<ProductCode>{FCFFE6B6-BAE8-490E-88D0-097A9DA1C43D}</ProductCode>

Can you check Bootcamp.xml on you BC drivers USB?

If you do not have a USB, you can create a BC drivers USB using BC Assistant. This is a screen shot from El Capitan (older versions of BCA also support the same functionality under the Download Software option...).

Oh, reinstall the entire Boot Camp package? Got it.

I'll reinstall the removed Windows updates, replicate the problem, remove the current driver and device, and reinstall the Boot Camp driver package this evening and let you know how it turns out. Thanks.

Before you go through with labor-intensive steps. Can you take a look at https://msdn.microsoft.com/en-us/library/windows/hardware/ff546200(v=vs.85).aspx and remove the driver from the store after you uninstall the current device driver and remove the device. Once you have removed it, then try to install the older W7/W8+ driver.

No updates on how you tried to solve the problem?

I'm struggling with the very same problem here, have the same 27" 2013 mac, tried the same solutions. Nothing worked, so far.

Please see WiFi issues on Windows 10 using bootcamp for a possible solution. There is a W10 Update that may resolve your issue.
