Almost every time I turn on my PC my ethernet connection does not allow me to actually use the internet, I have tried re installing my ethernet driver multiple times, using a different port on my router, but the only thing that makes it work is if I unplug the ethernet cable from the pc for about 10 seconds everytime I turn it on and then plug it back in. I built this pc only around 4-5 months ago. It is a 30m cat5e cable. Does anyone have any idea what the problem is?
