Lost Wifi Intel-NUC6CAYH

Hi, I've been running Ubuntu mate 18.04 on my Intel-NUC6CAYH without any issues, wifi has been normal with good speeds. I turned it on today and no wifi at all, no wireless chip even detected, the only change has been a recently purchased usb 3 hub that I plugged in on my last boot up.

I also bought a Toshiba usb 3 64GB flash drive before this, but it was not recognized by my NUC when plugged into any port, I bought a Sandisk usb 3 64GB one which worked perfectly, but when I plugged the Toshiba flash drive into my new usb 3 hub it worked. The other strange thing I noticed was my screen blacks out for a split second when I plug a flash drive into the hub.

I tried my live cd but still no wireless connectivity, could the usb hub or the Toshiba flash drive disable my wifi adaptor or could this be a hardware failure, is it possible to determine wireless status in the bios, thanks.

Hello ricky65,

Thank you for posting.

Our recommendation in this case is to troubleshoot the issue you are facing with the wireless adapter and the USB flash drive. Since you are using Linux, you need to check with https://ubuntuforums.org/ https://ubuntuforums.org/ or https://askubuntu.com/ Ask Ubuntu for peer to peer assistance. There is no option in the BIOS to check wireless status.

Thank you for your reply, I have done all of the trouble shooting on many Linux and the Ubuntu forums before posting on the Intel forum, all commands to check the hardware, wireless adaptor etc, show it as missing or disabled, I just needed to know if this could be checked or enabled in the bios. It is not just Ubuntu, another person using a Intel NUC running Windows 10 has the same problem after he used a usb 3 hub.

There are many accounts online refering to usb 3 devices stopping wifi and bluetooth, this could even damage hardware according to some experienced pc builders and they advise people to avoid usb 3 devices and only use usb 2.

Can you please let us know the part number of the USB 3 devices you are using?

Anker USB 3 Model AK-A7507011 (Gen1) Type 5000 Mbits.

I think it's USB 3 causing the problem with many motherboards.

Thanks ricky65.

 

I recommend to remove all input devices to test if the wireless works. If it does, test one input device at a time to find the one that may be causing the issue. Since Intel cannot guarantee all third party devices will work, we recommending using products validated by Intel or other customers. Here is the link to the current list: http://compatibleproducts.intel.com/ProductDetails%3FprodSearch%3DTrue%26searchTerm%3DIntel%25C2%25A... http://compatibleproducts.intel.com/ProductDetails?prodSearch=True&searchTerm=Intel%C2%AE%20NUC%20Ki... +

Hi, after a lot of system restores and changing my usb hub to a type 2 my wifi is back, not sure if it was a usb 3 hardware issue, there was also interference with hdmi output when plugging a usb flash drive into the hub, or a power issue with the hub, another person left a review of the same product on Amazon about how it messed up his Windows pc, full reinstall needed. So it could just be a quality control issue and mine was a faulty one.

Thank you for your patience and help.

Sure ricky65, you're welcome.

I am glad to hear the Wi-Fi is back and that you were able to track down the issue to the hub.

If you need further assistance let us know.
