Ok so just built new pc and runs fine. Pluged into router works good. Then I get a large eithernet cable so wire through roof to connect my pc to router from a different room. It’s retardedly long, across my house and maybe used a quarter off it. After couple min it stops working. I unplug it reset router multiple times still not working. And the dame thing nocked out the wifi do when I go on my phone it connects, but the. Says there’s no internet. I’ve reset my router multiple times and now using data on my phone to ask this.
