Okey so first of all my internet worked fine for like 3 years and after i reinstalled windows i started to get some issues first my internet got some red cross thing on my internet connection and after i troubleshoot it it said that i need new drivers after that i heard for some solution that if i change my speed and duplex thing my internet will work and that happend also i changed my router and ethernet cable and just to know i tested it on all devices in home and that ethernet cable work perfectly but it doesnt work on my pc.So i am suffering for more then 2 weeks trying to find solution and all of the sudden my internet would work for 1 hour if i lower speed and duplex thing to 10mpbs but after that it will stop working now i dont have that red cross thing but i do have yellow triangle and also it says that i have unidentifed network and when i start troubleshoot it says that my ETHERNET DOESNT HAVE VALID IP CONFIGURATION.
I tried everything from things in cmd and chaning some ip adresses everything but nothing works.
