when i connect my bluetooth headphones my wi-fi connection starts going crazy.
it works for few mins and falls down for almost a minute, and again and again in a circle.

OS: KDE neon User Edition 5.18 x86_64
Kernel: 5.3.0-40-generic

rfkill output:

Code: Select all

ID TYPE      DEVICE      SOFT      HARD
 0 bluetooth hci0   unblocked unblocked
 1 wlan      phy0   unblocked unblocked

please help me, I don't even know how to approach it
