So i was forced by my internet provider to upgrade my router. Just before i changed the router i did a speed test on my main Desktop to check if my internet speed would get better (i got 81 mbps download). I followed the guide that came with the router and changed the router to the newer one. I noticed that my Desktop couldn't connect through LAN, even though i was connected there was an "unplugged" icon in windows, once every 10 sec or so it would try to connect but fail every time. So i tried the same cable with a Laptop and it worked fine no problem there, i tried all router ports and only changing the Speed & Duplex to 10mbps Full/Half did help. So it cannot be my cable nor network adapter because 10 min before changing the router i was getting normal 80mbps download on speed & duplex set to auto and i checked the cable with a Laptop and got 420mbps download.
Updated the network drivers manually
