Anyconnect Secure Mobility Client kills WI-FI when trying to establish a VPN connection

We have a lot of HP Zbook 15 G3 workstations.  Few of them cannot use there Anyconnect Secure Mobility Client version 3.1.07021 over WI-FI.
When ever they try to establish a VPN connection to our corporate network from home (or other places outside our network)  the cisco client kills/disable the WI-FI connection, and they have to restart the laptop to get the WI-FI to work again.
I have tried a lot of solutions to get it to work, but I soon have to give up.
We are running Windows 8.1 x64 Enterprise on the laptops.
The laptops are fully updated from Microsoft Update, and we use HP support assistant to update all drivers...
Some of the things I have tried:

Reinstall the Cisco client.
Tried to install and older version of Cisco client.
Uninstall and reinstall the WI-FI adapter and drivers.
Tried to update Wi-Fi driver from Intel.com
Run Cisco client in Windows 8 compatibility mode .
Disabled power management on the network adapter.
The error in the systemlog is:
error ID - 10002
Wireless Expansion Module is stopped
Source = WLAN-AutoConfig

Its not an option to reinstall all the laptops that fails, some of the users have a LOT of speciel programs installed and configured.

I don't understand the "have to restart the laptop" part - is there really no other choice?
Did you try to just start that service again?

The users dont know what a service is on a computer :-)
We can sometimes start the WI-FI network again by using the hardware button on the laptop.
Haven't tried to restart the service, I'm more interested in why it doesn't work, I have newer seen this behavior on a computer before, and keep in mind, its only a few of many , and only on that model.
They are all installed from sccm 2012 with the same image...

Consider a different VPN client. I use NCP Secure Entry and all my clients use this as well. Works with Windows 7, 8, 8.1 and 10. It works with wired, wireless and cellular.

My clients like it because it is trouble-free and so is completely convenient for them.

Not free, but definitely worth it,

could you have a group policy that disallows wifi adapters?

Hello David.
No, if I had a GP it would affect all the computers in the domain, not only a few of a specific PC model :-)

There might be an issue with the service on some machines only. No cure, but a workaround then is to allow the WIFi service to restart after failure. Using the hardware button might do that. It's worth trying.

Make sure that the LAN ip they have prior to attempting the VPN connection is not the same as the one at corporate.
The other, make sure that those individuals configuration is not securing all traffic via the VPN.
Depending on your settings, has thought been given to try and use built-in VPN on the laptops.
Your VPN client package, did you create it or is it a Cisco installer.  Question when the client install package was configured, it is bound to any wired .......

After some more tests Sunday morning, I found the problem, (and a workaround) in the BIOS settings. If I disable the Lan/Wlan autoswitch setting, the Cisco VPN works without problems, I'm just wondering why its only a problem on a few laptops. I like to have that setting enabled, but it seems that I have to accept that I cant :-(
Maybe an upgrade of the Cisco anyconnect client will solve the problem, I have to test that..

Thanks a lot for all your comments, its nice to have some people to write with, when problems gets in over your head :-)

Best regards
