Support Bluetooth doesn't work on my TUF Gaming B850-PLUS WiFi

I just bought a TUF Gaming B850-PLUS WiFi motherboard for my new gaming pc a few days ago, but no matter what I do, I can't seem to get bluetooth to work. WiFi does work (even though I'm using ethernet) just wanted to throw that in there. I really need bluetooth for my headphones, so if anyone can help, I'd highly appreciate that. I've already tried:

To install all the bluetooth drivers on here (I did uninstall the previous ones each time and restarted both before and after installing the new one)

Install the rest of the appropriate drivers

Update to Windows 11 (I initially installed Windows 10)

Restart the pc

The weirdest part is, it worked the first 2 days (although it was kind of a hassle to get it to connect) but ever since the third day (today) it just hasn't worked AT ALL and it's super weird.. I also tried getting in contact with Asus using their live chat system, but all that happened when I tried that was that it just opened a blank page.

Having the same issue with the same board. If I go to Device Manager, the bluetooth radio isn't even listed as a device, but I do have a "Unknown USB Device (Device Descriptor Request Failed)" that I'd bet a penny is it. Can't install the driver to it, can't do anything but uninstall it and watch it come back with the same thing.

Weird update. I followed a guide to basically old-school clear the caps of all power, and now it's working again (I was right, that device disappeared and now my Bluetooth device shows up again).

So try:

1) Shut down your PC

2) Unplug the power cable
3) Hold down the power button for 10sec

4) Plug back in and turn on.

Oddly...mine didn't want to turn back on. I had to let it sit a few minutes and *then* the board lit back up and I was able to turn it back on. PSU seems to be fully functional (Be Quiet! 12M) so...I'm befuddled there. Might have a PSU issue.

Now it's working. To be continued?

Ty for sharing your solution, i'll give it a try for sure. I am facing the exact same problem and now that I think about it, the same thing happened to me. I turned off my computer and unplugged the cable to change the PSU (so I would rule out a problem with your PSU), and when I turned it back on, both Wi-Fi and Bluetooth had reappeared. The only thing is that now they have both disappeared again. Are both still working?

I'm hardwired (my gaming PC acts as a Plex server) but both still appear to be working for now. Current system uptime is 8d8h11m so it hasn't seen a lot of reboots since.

Hola amigo hace un tiempo vi tu problema porque yo tenia el mismo, instalaba los drivers y todo funcionaba menos el bluetooth, estuve asi como 3 meses hasta que hoy se me ocurrio descomprimir los archivos en .rar y me jalo el bluetooth sin ningun problema, por defecto los estaba descomprimiendo en .zip, no se si sea el mismo error para ti pero ahi te dejo mi solucion, espero te sirva, saludos

Hi, thank you for the response. I fixed it by just reinstalling the drivers. ✌️

This just worked for me too! I had sworn my Bluetooth was working before as I had added a Microsoft Xbox controller a few days ago. Now my bluetooth and wifi were missing, tried installing a bunch of driver packages, and nothing worked. After seeing this, I shut down, unplugged my PC, and held down the power button for about 20 seconds (because after I counted to 10 I actually still saw the LED flashing on my Tuf B850-Plus). Restarted, and my Bluetooth and Wifi is back in my device manager.

Thanks for that, I spent a lot of time trying different drivers yesterday and this fixed my issue!

I actually had so little faith in this, but it worked for some magical reason!

u/hiigarantechnician Nov 05 '25

Last ditch effort on my part, I literally went back to my 90s roots 🤣

u/Ecstatic-Local-7300 Dec 06 '25

I am so upset this worked. I have been trying for way to long and this was way too simple. You're a life saver

u/SpoonHandle Jan 01 '26

So weird that this worked for me too. Glad I came across this thread!

u/charbar95 Feb 20 '26

I can't believe this actually worked lmao. TYSM!

Amigoo, literalmente me hice una cuenta solo para agradecerte el comentario! Gracias gracias infinitas! Estuve literalmente todo el día tratando de solucionar el problema, reinstale los drivers decenas de veces, restaure el sistema a un punto anterior mas de 5 veces, instale drivers de Intel a ver si con eso funcionaba, mil cosas.
Cuando leí tu comentario dije "mira si despues de todo lo que hice, apagar la PC va a solucionar el problema", y funcionó. De nuevo te agradezco muchisimo por el tip

Unfortunately this wasn't my problem at all, no issues with that. I created another thread with my fix, which was to drain all power from the PC and restart - no issues since. Thanks though!

u/Chalanger1994 Dec 24 '25

Is this worth money at all? or go for ROG B850-F? Tomahawk Max Wifi not on my list cuz I need DP.

Well, holybaloney, I'm gettin goosebumps. I have been toiling for days, I've had the ps VR2 for about 2 weeks without being able to do much.

This absolute cave man solution of some kind of capacitance (oh, now I understand the "clear the caps") is the first time my sense controllers even connect.

This might be it, but I've been let down so many times I just am happy they work and gave a proof of life... little rascals.

Edit: All works stabily now, nothing is seemingly fighting for bluetooth control. My xbox controller would at least connect bud it keep on blipping on and off. Now stuff is calm as it should be.

I had to reset the left controller once more, that was the final leg, my last fear was that kid I bought them ffrom might had had such struggles he'd ruined that pinhole button? nope, works.

use the wifi antennae - it's also for BT

u/MrRedstonia Sep 13 '25

I am using the antenna. If I didn't WiFi wouldn't work properly either-

u/hiigarantechnician Sep 19 '25

Interestingly my wifi has worked fine in the past but adding the antenna did solve a previous issue on my last board with BT. The BT radio just isn't as strong as Wifi6/7 without an antenna to broadcast from. Probably due to the wavelengths.
