“…will be ready in windows 11 or later.” not sure what this means, but it sounds like drivers will be difficult. when you open Garuda Assistant what does the System Components tab say about Bluetooth?

in system components bluetooth support, bluetooth enabled and user in ip group are all enabled, bluetooth auto connect and pulseaudio-bluetooth-autoconnect are both disabled and i am unable to check the boxes

4

no those are unneeded. Its got to be drivers related. try dmesg | grep -i blue

wow it didn’t even try to load any bluetooth drivers or anything.

Yeah…

run systemctl status bluetooth
may require sudo idk

Im still very new to linux so this is greek to me

is the end of that “(ConditionPathIsDirectory=/sys/class/bluetooth”
if it is that sucks bad because my system literally has no bluetooth or wifi hardware at all and says the exact same thing.

11

This is all it shows

You have to scroll or go fullscreen to see more but that looks like a dead end.

→ if you open Garuda Settings Manager and use the Hardware Configuration option and at the bottom check “Show all devices” does any bluetooth related stuff show up in that device tree?

13

It does just end there even on fullscreen.

in hardware config. could the RTL8125 2.5 GbE controller (Realtek Semiconductor Co. Ltd) be bluetooth related? thats the only thing i see that may be

14

no that is Ethernet I think. I am not very good at wireless diagnosis and fixing on linux as I simply do not use any of it having wired internet in my house. @SGS is there a way to mark a post as someone tried to help but it needs escalation

Thanks for your help, appreciate it

Hey @Indigoknight .

Unfortunately you’re far from the only one having problems with their Mediatek MT7921 Wifi/Bluetooth combo chip.

There are quite a few threads on our forum and tons on the net with complaints about your adapter model not working. That chip has been super problematic since it was first introduced several years ago.

As your driver is included in the kernel, your most likely solution will be running an alternate kernel. There is a possibility that another kernel has better support for your adapter. The linux-mainline kernel would likely be your best bet, as it would include the most recent driver updates from Mediatek. It would be a good idea to test further kernels as well, such as the linux and linux-lts kernels (and perhaps others).

Failing a kernel swap providing a fix, your next best bet would be to reset your hardware. To do this, power down, then unplug all attached peripherals.Unplug your computer and let it sit for several minutes. After the power has fully drained from the mobo, plug your computer back in and power up. Next, press the key required to enter your bios settings utility and then perform a factory reset of your bios. Sometimes this procedure will help to get wifi or bluetooth detected properly and working again.

Juggling your adapter’s firmware version in /usr/lib/firmware/mediatek has sometimes been known to help with your model’s frequent breakages. If you want to try that it involves renaming, moving, or symlinking, so that another firmware version is loaded instead.

This adapter is a real headache, I wish you best of luck getting it working.

Yesterday I had the problem that BT was not working. I shut down the notebook and rebooted and BT worked again. I wonder if that always helps :wink:

I have the ROG STRIX B550 Wifi 2 is near same as your TUF but you have other chipset for Bluetooth and Wifi.

My Bluetooth is working but not for a Xbox one controller too. Its connect and disconnecting in 1 second so its not for using for bluetooth since they integraded the driver in the kernel. but if you connect with a usb c Cable you can check it with AntiMicroX and setup the buttons how you like for Games. May you need a usb bluetooth dongle for working i dont have one for testing but cable works :wink:

have you checked your bios settings onboard configuration that bluetooth is enabled?
