How to resolve wifi and bluetooth conflict?

Question

Bluetooth

I recently bought bluetooth headphones, I wanted to listen to music at home on Wi-Fi, and I realized that it was terrible, because the speed of my home Internet drops to almost zero, I watched a bunch of videos, dug up the entire Internet, and all I found was either to buy a router on 5 GHz, everything would be fine, but I don’t have money for it, and for a phone that supports such frequencies, or set the channel width to 20 MHz in the router settings, and change the channel (1,6,11), I did all this but not really helped, rummaged in the settings, set wi-fi prioritization, at first it helped, the tracks loaded very quickly, but right now everything is back to where it started from. I tried using software with root to disable some item (a friend threw off the solution to this problem), it didn’t help either, please tell me how you can solve the problem without spending money, and mobile Internet,

What devices are we talking about?
If we are talking about a laptop, then buying an external bluetooth adapter that can be plugged into the USB port will help.
