Sorted it now. Had to go into BIOS and enable internet connection.
My Dell xps internet was working fine yesterday (wired connection) but then all of a sudden the internet stopped working even though the cat6 was plugged in to the router. I tried different cables to see if the cable was faulty but it turns out that my network adapter is missing a driver. I checked what network adapters are inside my motherboard but its come up with like 12 different network adapters. How do I know which one i should install the driver for? Also where can i find the correct driver to install? I should also note i set my pc back to a date which it was in 4 years ago since it was really slow and i wanted to improve its performance. I searched all over the web to find solution to my problem but none of the solutions at hand worked. 1 solution was to change the properties on my "Local Area Connection" but i haven't even got "Local Area Connection" icon for some reason (i have never seen a computer not have this icon before". It is like my computer is completely not picking up the connection from the router and even worse its as if its repelling it... Anyways, signed up to this forum to see if one of you guys could help out :).
