Little backstory,we bought a new router,asus AX1500 ,set it up and everything was nice,we have the cable coming from the ISP into the router,then from the router 2 cables for my and my dads pc,the point is that i know the router has 4 ports on the back,LAN1,3,4 are for 100mb/s but LAN2 has 1000mb/s. The point is that my pc constantly switches between 100mb/s and 1000mb/s,i am not doing anything to it,i left it like that since i set up that router. On the router config page i can't do anything about the ports or using QoS just messes up things even worse. I also tried that setting on the networking card ,setting it to 1.0 GB/s duplex,it just disconnects my pc from the internet. My point is,why is it always switching? What can i do? I ran out of google answers so this brought me to you. Thanks in advance!
