WiFi and Bluetooth missing from surface pro 6 all of a sudden

Question

Hi,

All of a sudden in the middle of using the internet my WiFi and Bluetooth disabled. 

If you trouble shoot it displays that the network driver is missing or not installed. 

I downloaded the latest driver update manually via USB and tried updating drivers nothing changed stated my driver where all up to date. 

In the device manager if you display hidden drivers you could see Bluetooth and Marvell AC-wireless adapter. If you opened their properties they stated driver not installed or working properly (code 45). 

Tried all ideas suggested in forums nothing seemed to work. 

Performed a system recovery to 24hrs before system error occurred as a last resort. Now the drivers don't even display in the device manager. Manually updated driver from USB again still nothing.

All other functions working only Marvell AC-wireless adapter and Bluetooth adapter missing/ not working. 

Any ideas?? or could this be the the actual hard wear broken? 

Surface still under warranty however i'm in a different country to purchase. 

Regards Crhis

Hi chrisPraeger,

Thank you for reaching out to Microsoft Community. Im sorry to hear about what happened to your Surface Pro 6.

Please try to boot the device to the UEFI screen then check there if Wi-Fi and Bluetooth are enabled. Check this page on How to boot to the UEFI settings. Once you are in the UEFI screen, choose Devices then look for the Wi-Fi and Bluetooth option. If they are disabled, enabled them. If already enabled, try to disable them first then re-enable.

If this answer your question, we highly encourage you to inform our Community by clicking on Yes or marking my post as an answer. This will help other members who may have the same issue as you. Otherwise, don't hesitate to update us so we can further assist you.

Hi Marrion. 

Thankyou for your prompt reply.

I have followed the steps above, in the UEFI setting WIFI and Bluetooth where enabled. 

I disabled them, then re-enabled them with performing system restart between cycles just make sure it has taken effect. 

I have also performed a complete reset of the surface after saving all of my files. 

The controllers/ adapter still do not appear in the device manager. 

Thanks

Hi chrisPraeger,

Thank you for the response. I'm sorry but I think we need to proceed in re-installing Windows on your Surface Pro 6 using a USB Recovery Image. This option will reimage the entire device and reload Windows including the drivers and firmware. It is the most complete form of Reset and it will wipe out everything on the device so you might need to back up your files first. You will need also a 16GB/32GB of flash drive that must be formatted into FAT32 prior to downloading the Recovery Image. If you like to try, you can follow the steps provided below:

How to Download, Create and Use a USB recovery drive

To download the Recovery Image:

• You'll need a PC running Windows 7 or later or Surface Device.

1. Visit the page to Download the recovery image for your Surface
2. Sign in with your Microsoft Account
3. From the list of Surface devices available, select the device that you need a recovery image for

Please note that while you will only be presented with devices that are currently registered on your account, you will also be presented with the option to get an image for a different type of device. If you try to use this option, you will be prompted to enter the serial number for that device 4. Download the recovery image using the button on the page 5. When the download bar pops up at the bottom of your screen, save the file in a location you will be able to find it.

 Format USB Drive:

• Note: Formatting a recovery drive will erase anything that is already stored on your USB drive. Make sure to transfer any important data from your USB drive to another storage device before using it to create a Surface USB recovery drive.

1. Insert your USB drive into the USB port of your PC.
2. From the desktop, open File Explorer
3. Tap and hold or right-click on the USB drive and choose Format
4. Select FAT32 as the file system and enter a Volume label to name the USB drive, such as RECOVERY, and then tap or click Start
5. Tap or click OK to erase the contents of the USB drive
6. Tap or click OK when the format is complete

Create a recovery drive:

1. On your Surface or PC, open recovery image that you downloaded by double-clicking it or right click then select Extract and then Extract all.
2. Select the USB drive you formatted earlier for the location and click Extract.

Use a USB recovery drive to reset your Surface:

1. Shutdown the Surface
2. Insert the USB recovery drive into the USB port
3. Press and hold the volume-down (-) rocker
4. Press and release the power button
5. When the Surface logo appears, release the volume-down (-) rocker
6. Surface will start the recovery software on the USB recovery drive
7. When prompted, choose your language options and keyboard layout
8. Select Troubleshoot
9. Select Recover from a Drive. Choose Remove Everything and Fully Clean the Drive. Recovering this PC.
10. If prompted, select Repartition the drives
11. If prompted for BitLocker Key, tap Skip this Drive

Kind Regards,

I am also facing same issue. 

After doing all the above also WIFI and Bluetooth are not working.

Answer 5

My situation is very similar to the original post -- I was on-line, turned away, turned back, and no Bluetooth or WiFi. I've tried all the update routes to no avail. Tried to reset through the OS system recovery to no avail. Last resort tried the downloaded recovery image. ****

Just wanted to let everyone know that so far I haven't found anything to bring back the wireless adapter.

If anyone figures it out please let us know.
