I have asked the computer vendor, they say it is good to replace Killer 1550i to Intel AC 9560 because they contain a same core, the only different is that if I install 9560AC, it can not use killer software.
I have re-install my computer but not help. However, I found that if I move the computer, the driver will crash very often, but when I uninstall the driver, and sleep the window, hit the computer D-surface some times, and reopen it, it will work properly sometimes.
