I have a freshly loaded Windows 10 installation on an Elitebook 840 G3. I have enabled LAN/WAN switching in BIOS and need the WIFI to turn off or go into airplane mode when docked or an ethernet cable is plugged in. What is happening is when the computer connects to a wireless network and gets an IP address and is then docked or plug into a LAN with an ethernet cable it retains the IP address from the wireless network. It also gets an IP address from the LAN network leaving me with two active IP addresses. This is not supposed to happen with LAN/WAN switching enabled. It should cut over to the LAN and drop the wireless connection.
In Windows 7 this was not the case. It would release the wireless IP address. I believe it put the notebook into airplane mode when it detected a LAN network. I have 4 laptops all the same model on Windows 10 that are acting this way.
I have:
updated to the latest BIOS 01.07 Rev.A
updated to the latest Intel Wireless LAN Drivers 18.32.1.2 Rev.P
updated to the latest NIC driver Intel 1219LM/V Gigabit Ethernet Driver for Microsoft Windows 12.13.17.7 Rev.A
I'm running out of ideas to try here. On Windows 7 on the 640 G2 model I also had to have HP Hotkey Support driver installed to make it work. Where the 9480m and 9470m didn't care and worked without it. I tried installing HP Hotkey Support driver for Windows 10 but also did not fix this problem. Also, apparently the HP Connection Manager does not work with Windows 10.... I was going to install it so I could at least see if the LAN/WAN switching was being recognized by the OS.
Any help or insight is greatly appreciated.
Thanks!
