Asus PCE-AC56 loose network for some seconds

[Ovarmer]

Hello,

I get trouble with my Asus PCE-AC56 and my Asus RT-AC88U, in fact randomly i loose my connection for some seconds, i take a screen to show you the problem. I think the problem is my AC56 cause the routeur continu to work (see pic). It's a really big problem specially in games..

I try with ethernet, of course, no problem, i try some option like disable energy mode of the card, the drivers is update, i try on the routeur some option like game mode or other, same! :/

If you have solutions or suggestions,

Thanks
And sorry for my bad english ahah
