Varios DELL machines having an unknown device ACPI\DELLABC6 – it is the WiFi switch support – via Dell Community
Posted by jpluimers on 2019/06/17
It looks like many Dell machines suffer from this: devmgmt.msc indicating an unknown device with identification ACPI\DELLABC6.
The odd thing is that the tool known for 10+ years as Dell Detect, but got renamed into SupportAssist does not detect that Windows needs drivers for it.
So a bunch of posts:
- [WayBack] Solved: RE: DELL Latitude E5470 unknown device ACPI\DELLABC6 – Dell Community
- [WayBack] LATITUDE E7270 ACPI\DELLABC6 driver – Dell Community
- [WayBack] ‘Unknown Device’ on XPS 13 (9350) running Windows 7 : techsupport
They lead to these download:
- [WayBack] Dell WLAN Radio Switch Driver | Dell US with [WayBack] Dell-WLAN-Radio-Switch-Driver_JK9WM_WIN_1.0.0.9_A05.EXE
- [WayBack] Dell Airplane Mode Switch Driver | Dell US with [WayBack] FOLDER03137561M/1/Network_Driver_PX8MM_WN64_1.0.0_A00.EXE
The first of these works on a Dell Precision 7710 perfectly fine.
The odd thing: without the driver, pressing Fn+PrtScr (turn off/on WiFi radios) just works (for details on that key combination, see [WayBack] How to Turn the Wireless Devices on a Dell Notebook On and Off | Dell US or[WayBack] Dell Precision 7710 Mobile Workstation Keyboard Guide | Dell US)
