Hoping this helps someone else, but I couldn't figure out why Bluetooth wasn't appearing in Device Manager then I started testing BIOS settings one by one and found it's due to an unrelated setting with HD Audio. When HD Audio is disabled, Bluetooth will permanently disappear until CMOS is cleared then Bluetooth reappears.

Bios Version: All current versions through 7E49v1A15

Steps to replicate:
  • Clear CMOS and boot to Windows
  • Bluetooth is present
  • Disable HD Audio in BIOS settings and boot to Windows
  • Bluetooth is missing permanently until CMOS is reset

Other settings don’t seem to affect Bluetooth and re-enabling HD Audio in BIOS does not re-enable Bluetooth. Also, yes, I'm running a clean install of Windows and tested with multiple versions and the Windows installation isn't the problem, it's definitely a flaw with the BIOS. It also doesn't seem to be a problem with the WiFi/Bluetooth mini-PCIE card itself as I've disassembled and checked that also.

I've also read others having WiFi issues. I don't use WiFi, but I haven't had an issue with the WiFi portion of the card. Other than Bluetooth issues, I was experiencing random freezes prior to AMD releasing the 6.10.17.152 chipset driver, but those seem to be resolved now.

Yep. After some shenanigans with other forums & after all that no sleep fog yesterday, while nodding off at the computer I accidentally clicked on a download folder and MSI emailed me directly just questioning my Qualcomm driver. I honestly thought I had already installed it twice because I remember downloading it twice directly from MSI's website. Maybe in my sleepiness I have confused that attempt with Linux, but it appeared I actually had a much older WIFI driver installed.
I've updated that driver now and can confirm that WIFI does now work with X3D Gaming mode turned on which was the cause of the dropped WIFI in the 1A1A BIOS release.
After also speaking to MSI on the phone they also confirmed in an email that they were able to reproduce the BIOS freezing on fan voltage attempts in the 1A1G BIOS release. I did try an unofficial 1A1D BIOS release, then went back to 1G to test again. MSI then confirmed they are looking at fixing that fan voltage freezing issue and will fix it on the next BIOS release soon.

I tried again in Linux but nope. Maybe a firmware blob will be the answer there.
I'm happy that MSI have provided direct & quick responses to me and being able to quickly talk to someone on the phone without going through too many phone options or departments has reaffirmed my faith in MSI as a reputable company to deal with.

With this update, the problem with typing numbers was solved for me, but I lost 800 points in multitread on the geekbench even compensating with more voltage. If I leave the voltage the same as before, the score drops even more.

Windows 11. Support told me to reset the CMOS again, and now 5 Gbps ETH, BT and Wifi are all back. BUT now Windows crashes on sleep again. It doesn't it I disable Wifi in the Bios. I see on other forums this is a known issue too. Anyone have any tips on this? (very close to returning the board)

It doesn't work. If for some reason my system crashes, the wifi disappears again, so I have to clear CMOS and configure everything again. This BIOS version is a mess for me, because the system is unstable, I've tried configuring PBO and DRAM, but nothing seems to work.

Update: Still buggy bios on X870E-Carbon Wifi. IF you enable AMD's dynamic overclock EXPO ram profiles of any kind, it shuts off the mobo's built in Wifi. Luckily I'm running LAN connectivity.
Bios revision is 7E49v1A27. Get it together MSI!

Still nothing, even just updated bios today. Re-installed wifi driver and still nothing. Default settings, wifi is turned on and recognized. The moment I do this and enable these settings on the motherboard. Wifi is shut off.
