ROG Crosshair VIII Extreme - Bluetooth and Wifi not working

[SimeJah]

So I got my ROG Crosshair VIII Extreme mobo about a month ago.
Everything is working fine except 2 things;
the Wifi and (more importantly) Bluetooth are not working.

I already tried;
- reconnecting the antenna (both ways)
- resetting BIOS
- Clearing CMOS
- triple checked if the devices are enabled in BIOS
- installing the drivers from ASUS website multiple times.
- installing 3rd party drivers
- installing legacy drivers
- Installing a fresh copy of Windows 10
- upgrading to windows 11

It is noteworthy that when I try to run the driver installer all I get is a brief flashing of a CMD window. It does not seem like it's installing much, but I could be wrong here.

Any help would be greatly appreciated.

Hi,

You need these drivers for your ASUS ROG Crosshair VIII Extreme motherboard :

- AMD Chipset Drivers

[DRIVERS] Intel Serial IO/Thunderbolt (3xx/4xx/5xx/6xx)

- Intel Thunderbolt Drivers

[DRIVERS] Intel Ethernet/WiFi/Bluetooth

- Intel Ethernet Drivers (Drivers Only) :

Drivers - I22x-V (2.5GbE)

- Intel WiFi Drivers (Drivers Only) :

Drivers - 9xxx/AX2xx

- Intel Bluetooth Drivers (Drivers Only) :

Drivers - 8xxx/9xxx/AX2x0

[DRIVERS] Marvell/Aquantia Ethernet

[DRIVERS] Realtek USB Audio (MB | Intel 5xx/6xx & AMD 5xx/TRX40)

You have an ASUS ROG SS3|DTS Sound Unbound motherboard with ALC408x codec, so :

You need Realtek USB Audio Drivers (UAD - ASUS ROG SS3-DTS MB) from the first post of the thread.

Follow scrupulously your CLEANUP process then your INSTALL process, for the next drivers packages that I would release, you will can directly follow your UPDATE process.

Thank you for sending these drivers (which are not listed on the asus motherboard page which I find both strange and disturbing.)

Anyway.. I cannot seem to install these.. You mention the following; "Right click on "mtkbtfilter.inf" > Install > Wait for the message "The operation completed successfully" or for restart request"

When I right click and select install I get a UAC prompt, I click continue, and... nothing happens. no message, no nothing.
How can this be? Is there any other way to install it?
Thank you!

Both devices you mentioned are not listed in Device manager. That is the whole problem. So I cannot do this technique.

Hello, I have same MOBO.
This board uses an Intel Wireless module, not Mediatek.
You need to install Intel drivers. Maybe this is what is causing your problem....
