yep. The wifi signal always break down while the bluetooth device is working. I checked my bluetooth options at the same time and eventually find out that there is no issue on it.

I find a possible reason for this issue, that is the frequency band the wi-fi use. 2.4ghz wi-fi might cause inter symbol interference with bluetooth. if you transform to 5ghz wi-fi, this problem can be solved automatically.

你是用的heliport吗

Yes, you can see native client of the picture in right's.

I‘m curious at how you find out the specific information of heliport and your current situation of wifi......

I find a possible way to solve this issue, that is fixed the channel of 2.4GHz Wi-Fi at 13 (aka. located the work frequency as far as you can). This can commendably improve the performance of wifi. I guess the main reason of this issue is that MacOS doesn't have
the cooperative mode between wifi and bluetooth for intel network card. Anyway, really appreciate for your help!

[jiaogger]

And caution: this method CAN'T perfectly solve this issue. If you want to throughly fix this problem, please buy a router that can work in 5GHz and linked with it. There is still accidentally stuck occurs, but it's in my comfort zone.
