Re: Intel Nuc D54250Wyk Drivers
Anastacia Iacono
I have a Intel NUC D54250WYK. Two years ago I added an Intel Wireless-N 7260 with bluetooth card to the machine. It was running Windows 8.1 at the time. I installed the relevant drivers and both WiFi and Bluetooth parts worked fine. This week I did a fresh install of Windows 10 (an upgrade wasn't working for some reason). Out of the box the WiFi was working but Windows couldn't see the Bluetooth device. Device Manager was showing an Unknown USB Device (device Descriptor Request Failed),so I was assuming this pointed to a driver problem? The Wifi card was using a Microsoft driver.
I downloaded bt_21.10.1_64 from Intel Wireless Bluetooth for Intel Wireless 7260 Family site and installed it. It made no difference. I then tried older drivers I had from before but again it made no difference. (Although the wifi card started using intel drivers).
I found this thread "Solved: Intel Wireless-AC 7260 bluetooth failed - Intel Communities" and followed the steps. I could only find one driver the bt_21.10.1_64 - the onedrive link in the thread didn't work. I don't know if that has the Wifi and/or the bluetooth driver. I can see the wifi card is still using a Microsoft driver and there is an unrecognized USB device in device manager and no bluetooth. It's like the drivers are not correct. Am I installing the correct drivers? Are there others I should use? I did try some random dell ones I found for the same card but it didn't solve the bluetooth issue. As it was working find under Windows 8.1 I don't believe its an install problem?
Then as I have seen suggested in other posts I removed the network connection, uninstalled both drivers and clicked uninstall from the device manager for the wifi adapter and the unknown device and reinstalled the bt and then wifi driver. Unfortunately the result was the same.
I discovered my BIOS was a bit out of date. I updated it, uninstalled the two drivers and reran the chipset software install. I then installed the bluetooth driver followed by the wifi driver. Still no change. It still doesn't recognize the bluetooth device.
Due to this product being discontinued, Intel Customer Service no longer supports inquiries for it, but perhaps fellow community members have the knowledge to jump in and help. You may also find the Discontinued Products website helpful to address your request. Thank you for understanding.
I had an issue with adding an AC7260 to an older ASUS laptop (K550 with Win 10) with a flaky wifi card (after months of troubleshooting). Bought this card for both WIFI and bluetooth, but bluetooth wouldn't work after installing it - wifi worked fine and random disconnects appear to have disappeared.
After more troubleshooting I came across videos suggesting to cover pin 51 and pin 20 (and or pin 21) on the 7260. From what I could see those pins control whether or not the 7260 can be controlled by the laptop (i.e. I can turn off the wifi on/off my laptop with a function key, but bluetooth was never an original option on my computer so no function key for bluetooth). Reluctant to take computer apart again unless nothing else could be found, I searched for another solution.
I tried an older driver and it worked for a while (I could actually see the bluetooth icon in the lower right-hand notificatiion area) until a windows/driver update was performed, then bluetooth was gone and no install/reinstall of drivers, nor system restore, could get it to return - so much for that.
I finally came across someone who suggested booting into a live linux session (I used a live USB of linux Mint - they suggested Ubuntu). Once booted into linux, enable bluetooth, then power off the machine. Reboot into windows and suddenly the bluetooth on the 7260 is enabled and functional! I couldn't believe that would work, and gives me hope that not only can I fix it again if/when it shuts off again, but also that there has to be a command/function/program to enable the bluetooth via software and not covering or etching pins to break contacts. If I manage to find a software fix I'll update here.
lmfao, hey buddy, god these people are sooo stupid lmao. i only know the exact solution, because i dealt with this years ago.
Its not driver related, its hardware install related. If you check the install manual, there is an image showing, that when you install the card, there is a small cable, that must be plugged in or powered, and it must be powered and installed correctly, in the instructions,
they even call it, "bluetooth cable" basically on yourmobo there are a few 8 pin slots to install a new usb port, this bluetooth, cable,
That'd be a good answer except that is for the addition of WiFi using a carrier card to a standard PCIe slot; it does not apply to the cases here, which are working with either laptops or NUCs, which have M.2 Type E connectors for WiFi.
