issues with using bluetooth at the same time as W-Lan

I tried using bluetooth headphones for a few months now with my NUC NUC8I7HVK2. But i recognized the following as soon as i use the headphones:

  • I have always some hiccups in the sound as more as i receive data from the W-Lan, like the NUC forgot to send bluetooth for a second.
  • The W-Lan speed plummets from 100 Mbps to 10-15Mbps when i use the bluetooth headset

I have done the following:

  • reinstall devices in device manager
  • reinstalled driver (clean de-installed and installed anew)
  • updated BIOS
  • updated Windows (10)

The Headphones work fine on other PCs/Phones.

Is this a HW Issue or can i solve this somehow with Software changes?

Thank you in advance,

First of all, Bluetooth and Wireless share the 2.4GHz band and can interfere with each other. Secondly, USB 3.0 also uses 2.4GHz signalling and a poorly insulated device or (especially) cable will cause interference. If you can use the 5GHz band for Wireless, you should always be doing so. If using a USB 3.0 device when problems occur, look at this device with the hairy eyeball. If you are doing all this and the problem still occurs, first thing to do is check that the antennas are properly connected to the component. Next is to look into whether you have a bad device.
