Last week I bought a new Asus Laptop running on Windows 11 (see detailed configuration below). This laptop comes with a Wifi and Bluetooth functionalities. Everything worked fine until Friday, when the Bluetooth icon decided not to show up in windows taskbar after startup.

I saw that this is somewhat of a common error and followed Microsoft's suggested fixes. I tried updating the driver and running the troubleshooter to no avail. Ultimately, I followed the instruction of uninstalling the Bluetooth adapter from the Device manager.

This is where things started to go south: after reboot, Windows does not detect my Bluetooth adapter anymore. I tried:

1. Starting "Bluetooth Support Service" in the "service.msc" tool;
2. Reinstalling new drivers from Asus website
3. Reverting back to factory settings (twice)

All this gave no result. I still do not have Bluetooth capability and the Bluetooth adapter remains absent from the "Device manager" (even though I am showing hidden devices and scanned for hardware change).

But there is more.

While trying to connect my laptop to my old Wifi router (which only emits in the 2.4GHz band), I discovered that my laptop can only see Wifi networks that emit on the 5GHz band. This is strange because my integrated network adapter, a Realtek 8821CE is supposed to detect both 2.4GHz and 5GHz bands.

According to the manufacturer's website, it seems that the Realtek 8821CE is also the chip that offers the Bluetooth capability. I therefore suspect that this chip is somehow malfunctioning and causes the 2 problems that I observed: failure of Bluetooth and Wifi limited to 5GHz band.

In the end, could you tell me whether my problems are caused by a software issue that I can solve, or is my network adapter faulty and I should return the laptop?
