wifi slow when bluetooth is working in asus laptop

I have an Asus x555q with Ubuntu 22.04 and I tried to make internal bluetooth work with Wifi but just connecting bt makes the wifi speed falls to more than 50%. I have read the guides [here](https://askubuntu.com/questions/1132509/difference-between-bt-coex-active-n-and-bt-coex-active-1) and [here](https://wiki.archlinux.org/title/Network_configuration/Wireless) but they not worked at all. any ideas? BTW I'm bearing this problem with more than two years without find the answer.
