LAN/WAN issue when Connecting to CISCO Anyconnect VPN application

[Leigh_W]

Hi

We are currently experiencing an issue on out soon to be "new company laptops" regarding LAN/WAN switching and the Cisco Anyconnect VPN client.

When LAN/WAN switching is enabled and the client is ran, upon a successful VPN connection the Wireless adapter is becoming disconnected, thus dropping the VPN connection then re-enabling the wireless connection

We have tried this on other machines, Surface and HP EliteBook 1040 G2 with the same Windows 10 image that we will be using and have no issue, from what we can tell it is just the x360's that are having this problem,

All latest updates, bios and Anyconnect client installed.

Due to the Volume of users in the business and how turning the LAN/WAN switching off in the bios will cause issues when re-docking the machines this is not really an option (plus the infosec team have told us we cant do it)

Any Help would be much appreciated

By chance did you ever find a fix for this?  We have the same issues on Elitebook 840 G3 but only Windows 10.  Windows 7 works fine.  Windows 10 used to work so it's either an update from MS or Cisco that caused the problem.

We are using cisco client 4.4.03034 and noticed when it connected it was disabling the Wifi. In the end it was the lan/wan switching. Temp fix was to disable this however there is a hotfix that has resolved the issue

This should be the correct link to the 840 g3 hotkey driver

My bad, we're actually running 840 G4's not the G3 and they already had the latest hotkey driver.  I re-installed the latest driver in order to test but that didn't resolve anything.  Currently our only option is disabling LAN/WAN switching in the BIOS which in and of itself is a big pain and our users have gotten so accustomed to not having to do anything with Wi-Fi when moving from docked to undocked I fear it's going to be a helpdesk nightmare.  

Thanks for the suggestion.
