hey i built my desktop gaming pc a couple of days ago but i have unstable network connection. I am using a cable to the router. The router is a Asus AC87U and the motherboard i have is a asus z170-a. I have installed all the drivers i need except graphics drivers (working on it now). Sometimes the internet work's, and when it worked i took a speedtest and it was only 10 gb/s down and up. I am having 100 mb/s down and up on my laptop with the same cable. When it does not work there is a yellow triangle with a black exclamation mark, and it says no internet accsess. Sometimes there is even a red sircle with a white cross. What do i do?
