XPS 15 9575 2-in-1 BIOS Setting Wireless Radio Control
Hi, I have an XPS 15 9575 2-in-1 and would like for the Wi-Fi to be automatically disabled when an ethernet cable is plugged in (into a WD-15 Docking station). This has been tested on several Latitude notebooks as working using the "Wireless Radio Control"-Option in the BIOS Settings, but on the XPS 15 it doesn't seem to work using the same setting. I've already updated the BIOS to the latest version (1.13.0) and all system diagnostics came back negative. Is this a BIOS bug or am I missing something? Thanks

Hello. Thank you for writing to us. Based on our conversation in private message. Your XPS is shipped with Killer 1435 wireless card and the WLAN radio control function is not supported with the Killer 1435 device. Should you want this functionality to work then you must use an Intel Wireless Card.
Do let us know in case of any additional queries.
