Prime B550M-A WIFI II both Bluetooh and Wi-fi 6 not working
Posted by YerrashSecond@reddit | buildapc | View on Reddit | 120 comments
I recently built a PC and thought this motherboard (Asus Prime B550M-A WiFi II, windows 11 ready) was a nice option for having the WiFi 6 and Bluetooth included. But I cannot make it work. I installed the antenna hardware properly, downloaded Drivers on the product website and Intel respective website.
I tried it on Windows 11 which is the OS I plan to use. I will make a list of what I tried to solve the problem:
- downloaded and installed all respective drivers (BT-22.140.0-32-64UWD-Win10-Win11, WiFi-22.140.0-Driver64-Win10-Win11, DRV_Bluetooth_Intel_non211_SZ-TSD_W11_64_V228004_20211022R and DRV_WiFi_Intel_All_SZ-TSD_W11_64_V228011_20211022R)
- downloaded and installed the ArmouryCrate for the motherboard
- downloaded and installed the chipsets
- check for any built static by turning it off, pulling out the power cable, held the power button for a while (30+ seconds) and turned it all back int. (Tried this a few times during my attempts to solve the issue).
- used windows troubleshooting
- uninstalled the drivers and reinstalled it through the manager
- tried some cmd prompt commands to activate wi-fi on start-up and such
I have been trying alternatives for more than a day and this is getting me really upset... Don't really know what to do anymore.
I got the drivers from:
Any recomendations?

Had the same issue in 2024 with my Prime B550M-A WIFI II but noticed seperately and didnt use the shitty asus armory software
The Realtek 8852BE WLAN driver is the correct one and does not show on the Asus page. I got it from here: https://support.lenovo.com/de/de/downloads/ds558080-realtek-8852be-wlan-driver-for-windows-11-64-bit-version-21h2-or-later-ideacentre-3-07ach7
The "Realtek Bluetooth Driver V1.9.1051.3002 for Windows 10 64-bit& Win11 64-bit---(WHQL)." option under bluetooth on the asus driver page fixed the bluetooth for me. Annoyingly windows kept insisting my bluetooth works and simply doesnt detect any devices but this driver fixed it instantly (from here: https://www.asus.com/motherboards-components/motherboards/prime/prime-b550m-a-wifi-ii/helpdesk_download?model2Name=PRIME-B550M-A-WIFI-II)

Thanks a billion, this worked for me too.
For the bluetooth driver, in-case anyone else makes the same mistake I did, don't get the driver "MediaTek Bluetooth Driver v1.1037.0.429 for Windows10, Windows11 64-bit" in the same link above. That doesn't work.
Get "Realtek Bluetooth Driver V1.9.1051.3002 for Windows 10 64-bit& Win11 64-bit---(WHQL)." as fitmedcook recommends.

Ur the fucking best holy bro I love you I couldnât fix this for days
Depressofox@reddit
How do i download a driver if i can't access the internet?
AzureDominus@reddit
This guy is the GOATTT. Make sure when you go on the second link (for the bluetooth driver) to press "Show all", then find the "Realtek Bluetooth Driver V1.9.1051.3002 for Windows 10 64-bit& Win11 64-bit---(WHQL)". Restart then everything is working as it should!!!!

Gabe164@reddit
for your bluetooth driver when you did the AsusSetup did it pull anything up or did it just work on it's own without having a setup window pop up?
Rajmundzik@reddit
Only short cmd windows for 2-3 second and it's finished.

GideonEpa@reddit
For anyone who still has this issue (2024):
Download ASUS Armoury Crate. (ASUS Software Manager)
Create an ASUS Account and register your motherboard using the serial number on the box.
Using the Armoury application, download all the recommended drivers.
Restart Computer.
This is what fixed it for me!
I also updated to the latest version of Windows 11.
Good luck and happy many hours of troubleshooting!
lukeshelley00@reddit
I can't download the ASUS armory crate because I'm not connected to wifi. I've tried downloading the drivers from the ASUS link in the threads above with no luck after running them and restarting
any ideas?
Big-Humor-8587@reddit
I know I'm hella late, just started using reddit. But a way you can attempt this is by hooking your phone to your oc with a usb c or whatever your phone charges with and use bluetooth tethering and make sure your phone is paired with your computer on bluetooth and bam. You have tempoary wifi to download stuff.
CryptographerOld3368@reddit
Did you ever find a fix? currently in the same situation
lukeshelley00@reddit
I had downloaded the wrong driver. The list that asus has on the product page has 5 or 6. After trying them all one at a time I finally got the right one.
Hope you were able to get the problem fixed
Pretty_Structure_215@reddit
This is the ONLY thing that worked for me. Thanks for the solution.
jezwel@reddit
Bought a second one (upgrading an old Celeron connected to the gaming TV) of these motherboards yesterday (with CPU, RAM and GPU) as the one I have in my PC has worked without any problems. Wifi working fine BTW, though I have ethernet so it's not needed.
I've tried everything I can think of to get wifi working on this 2nd board. Every driver. Started with a Win10 install. Tried a fresh M2 ssd and a fresh win10 install, then upgraded to Win11 thinking maybe the new OS will work.
Still no go.
BIOS has Wifi enabled, plus all the cruft to allow Win11 to be installed
WinAgreeable3445@reddit
Okay so guys i think the Asus support site works....i just decided to click "All downloads" and saw different versions Download Realtek drivers for Bluetooth and wifi
AffectionateYouth586@reddit
What right version is it for wifi and bluetooth
WinAgreeable3445@reddit
The REALTEK version
AstronautNumerous249@reddit
whats the right driver, there are so many
WinAgreeable3445@reddit
Use the one link that leads to a lenovo Realtek Wlan driver...worked for me
AffectionateYouth586@reddit
If there a windows 10 version?
WinAgreeable3445@reddit
I donât know tho but i think its supposed to work
YerrashSecond@reddit (OP)
For those still having problems, if you have no yet installed the Armory Crate, try doing so, it was the best and definitive solution for me. When it runs it updates and sets up the motherboard.
Over-Art567@reddit
Yo, This sounds great but unfortunately Armoury crate needs wifi to install, So i can't even install that, how did you get around that?
Bzone_Mx@reddit
Hey have you figured this out yet, i've been stuck on it, cant download Armoury Crate without wifi.
CryptographerOld3368@reddit
hey did you ever figure this out?
Bzone_Mx@reddit
yeah just went for the ethernet connection. When no one was home, i just put my PC on the couch, connected it to the TV (next to my wifi) and connected it to my wifi via ethernet, sadly thereâs no other option
AffectionateYouth586@reddit
Does it run off ethernet cable or wireless connection now?
Bzone_Mx@reddit
wireless connection, once the wifi stuff was installed then wireless works, but to do that you need wifi so i used ethernet.
CryptographerOld3368@reddit
Yeah Iâm starting to lean towards that being the only solution thank you though
iUseArchBTW69420@reddit
phone thetering is a thing if you still havent figured it out
rwrayyan2004@reddit
Tried this solution but wifi icon still didnt show up, netwrok adapter under unknown device and cant use any bluetooth :-(
AffectionateYouth586@reddit
How did you fix this
CryptographerOld3368@reddit
how did you install armoury crate without internet?
FlashGordon555@reddit
Old post but I had this issue yesterday, new build for my sister with used and some new parts. New storage and mb and fresh windows 11 install. Could not for the life of me get WIFI to work.
Downloaded all drivers from Asus support for Chipset, Realtek, Bluetooth, WIFI. Chipset and Realtek installed just fine. Wifi and Bluetooth Asus Setup app did nothing. I even manually used CMD to install the install.bat file in the driver download folders and even with a successful driver message in CMD, it still didn't work. Device manager showed my wifi under "other devices" network controller with a yellow triangle on it stating no drivers and cannot be installed. in an attempt to force a driver went to "update driver - browse my computer for available drivers - let me choose from a list - to where I attempted to install every available MTK driver listed for 802.11 and none worked.
Read this thread and saw your post about Armory Crate.
Installed Armory Crate and it stated I had Chipset, Realtek, WIFI and Bluetooth drivers available. Took 5 mins for frig sakes.
Kmingz@reddit
I installed it but now on the driver page it says "sorry, currently unable to retrieve available updates. please visit the ASUS official support to download" which i cannot do as I do not have internet on here. How did you get around this?
jmvv20@reddit
Hi, did you already solve this issue? having the same issue right now, what did you do?
ThisAccountIsStolen@reddit
The II board uses the AMD/Mediatek wifi card.
https://dlcdnets.asus.com/pub/ASUS/mb/08WIRELESS/DRV_WiFi_MediaTek_XB468NF_SZ-TSD_W11_64_V3011203_20211026B.zip
Download for the driver for your wifi card, for W10 or W11.
Edit: here's the main driver page for your board, since you have the original board linked, this is for the II model. https://www.asus.com/Motherboards-Components/Motherboards/PRIME/PRIME-B550M-A-WIFI-II/HelpDesk_Download/
AdLocal2383@reddit
my Bluetooth works fine now but my wifi still not working. Any other Solution ?
Turbo2jzge@reddit

Maleficent-Ant3931@reddit
This worked for me. Thanks bro!
Good-Quantity-4839@reddit
Thank you for this youâve just saved me there. Do you know if it needs to be/ can be updated in the future though?
Turbo2jzge@reddit
Well whenever you update your drivers just donât do a clean installation so the drivers wont be deleted it has beeb working for me like that
PLCwithoutP@reddit
Thank you, this worked for me as well
Head_Net214@reddit
Hi! I downloaded the second link but i canÂŽt run the driver, i just try to run it as an administrator but nothing happens.
ThisAccountIsStolen@reddit
You can try right clicking the install.bat file and running that as administrator, or if that still doesn't work, you can find the mtkwl6ex.inf file, right click and choose install. The inf file is the actual driver, so that should do the trick if all else fails. I've found the asussetup.exe to be unreliable myself. Do note that with all but the last option, you may only see a command window pop up briefly on the screen and then go away, you won't see any confirmation or anything.
One thing to remember is to make sure to extract the zip file first. If you try to run it from within the zip file itself, it won't work.
Head_Net214@reddit
Follow your instructions but nothing happens, no problem dude, tomorrow I will buy a usb bluetooth dongle , thank you so much for your response!!
ThisAccountIsStolen@reddit
Have you tried rebooting? It's possible it installed and just needs a reboot to start. It only takes a second to install, and the command window may have appeared and disappeared so fast you couldn't even see it.
And just to confirm, you're sure it's the "II" version of the board? The original used Intel wifi, which is a totally different driver.
When you open device manager, do you have an unknown device listed (should have a yellow triangle with an exclamation point on it)? If so, you can right click it and choose install driver (it may say update driver) and point it to the folder where you extracted the zip file, and it should pull that inf file in and install it.
I'd hate to force you to get a USB dongle if the board has WiFi built in.
rwrayyan2004@reddit
My board is the PRIME B550M-A WIFI II board
Issue is that i cant seem to see the Wifi icon anywhere, only ethernet is available. Bluetooth doesnt seem to detect my mobile hotspot as well
ethayden97@reddit
Did you ever figure this out
toothylobster@reddit
got to armoury crate- Tools - drivers - hit install this fixed it for me hope it helps
AstronautNumerous249@reddit
what do you mean
Ordinary-Wishbone427@reddit
this worked for me thank you!
CheeseBreadPerson@reddit
I checked my Device Manager and it did not show any sort of Mediatek Wifi Card
SunBear_00_@reddit
Same, on the asus driver page you will see the driver for wifi.
Download it, extract it, run the Asus set up application and then it will add these to your device manager.
I found this thread yesterday and managed to install WIFI/Bluetooth etc and now the device manager is updated accordingly.
Baki8365@reddit
I love you
Ambitious_Pension_15@reddit
My Motherboard is same as this guy but my wife is 2 how I can fix that?
A_Harmless_Fly@reddit
Any advice to someone who has the same board but the asus driver downloaded from their site isn't doing anything when run? All the other drivers for the motherboard worked, but nothing happens when I run one of the wifi ones.
KelloggsCrispix@reddit
This helped me, thank you so much
Psickodrums@reddit
Hey, so I followed the whole post and nothing helped me out. My issue is with Bluetooth, I'm trying to connect my DualSense via BT, but when I try to add the device, nothing is shown on the BT menu. I downloaded BT drivers, Armory Crate, everything is updated and still nothing, it's like it doesn't detect any kind of BT source, any ideas? Thanks in advance everyone
Bragdon_@reddit
Were you able to figure it out. Having the same exact issue and unable to pair anything. TIA
zero-mp4@reddit
Hey, does anyone know how to get this to work in Windows 10? I refuse to update to Windows 11, and trying all the drivers from the Asus page didn't do shit for me. There's no way the antenna isn't plugged in properly because it won't screw anymore from how tight it is, wtf is the problem?
Silly_Baseball_4616@reddit
Hey if anyone facing any wifi issue download realtek wifi driver it worked
WinAgreeable3445@reddit
What about bluetooth?
Apprehensive-Safe-35@reddit
Thank you. Mine was Realtek and this issue is dumb asf
Real-Pit121986@reddit
None of the drivers are working for me. I've tried every single one.
WinAgreeable3445@reddit
Tried the realtek Wlan driver?
CPlayyz@reddit
Is there any updated version for this? Asus drivers are not working for Wi-Fi on my PC
jakkoladdo@reddit
Did you fix it?
CPlayyz@reddit
Yes I did. I talked to ASUS support for about half an hour and they gave me a couple files to try and download. I had to use my other computer though which was a pain but I didn't have ethernet so there was no way around getting a USB drive, plugging it into my PC, putting the files onto the USB drive, and then putting the drive into the PC. The support was very helpful though.

ActualFix
For those who are out there still wondering what is going on.
I googled the hardware Id of the unknown network in device manager, which led to being a realtek 8852BE wifi driver rather than medialtek...
I googled some more on " REALTEK 8852BE" and came across several vendors. Being me I didn't want to manually look for the latest version so I clicked on the "Lenovo" link and downloaded it. It installed flawlessly and now I have wifi...
Id advise you from this point to update the drivers... If not sure how something like armoury crate will do it for you

Bonjour, j'ai installe ma carte prime B550M-A WIFI II hier et impossible d'avoir le WIFI. Le module WIFI est bien sur "enable" mais impossible de le voir dans le gestionnaire des tache.

BabyFood2@reddit
Hopefully installing this driver will solve it. If not, check device manager for any wifi device or any device you think doesn't belong there and right click it and click uninstall. Then install the driver.
I had previously forces install of other drivers hoping it would work. I believe I tried mediatek wifi 5 instead of 6 and it failed to work. So I had to uninstall it from device manager before installing the driver in the link I provided.
Best of luck đ€đŒ
