Windows 7, Wired Ethernet Connection not working randomly after 3 years, PLEASE HELP!

Hello there,

I was on my computer during a storm and after some lightning struck near my house, my monitor flicked off and on again and I lost my wired connection to the internet. The computer icon in the bottom right of my screen usually showing my connection to the network had changed to a red cross, which usually means the network isn't connected.

I thought this was strange, so I decided to restart my router. After doing so, the computer icon had changed from a red cross into a yellow exclamation mark. However, the wired LAN connection still didn't work and told me my wired connection was on an "unidentified network".

I read into this only and read that I should try to turn my computer's power off completely and leave it for a few hours. I decided to do this and unplugged my computer from the mains for a few hours. I returned to my computer a few hours later and turned it back on, only to discover that the computer icon now had turned back to a red cross, and my computer was not even detecting that the wired cable was in the LAN port. In the Device Manager, under Network adapaters, the wired LAN driver is not appearing. The light on the LAN port is orange when the wire is not plugged into it, and turns a bit green when the wire is in.

I used my xbox 360 to test if it was the wire that was broken, and the wire connected my router to my xbox just fine. I downloaded an update on my xbox to confirm the internet worked through the wired connection and it does. Afterwards, I unplugged the wire from my xbox back into my computer, but it still was unable to detect a connection and still displayed the red cross on the computer icon in the taskbar.

I have been searching for a solution for days but I cannot find anything, so please somebody help me! I have updated my Windows to the most recent update today, but still not working.. I will be checking this thread all day and bumping for multiple times because my wireless internet is so slow!
