Hi wb,

So if i set them off,its would cause the rate of flow going down or not?

By the way can you tell me what kinds of situation would cause the net adapter to reset?

Thanks!

Best&Regards

Hi Leo,

 

It is possible. There many possible reasons such as defective network adapter or traffic overload.
