Computer not detecting LAN on second boot

[Mutta Bones]

Yeah, the situation as stupid as the title sounds.

For the longest time,  I've had this very old computer that I've been wanting to upgrade. It obviously has no wifi built in, as it was barely 150$ when I bought it. So for the past 6 years, I just got a dongle, (more like a thumb drive) and it worked.

Just to make this clear, I have my router set up in the living room and my PC goes in an adjoining room.

Now I got a new rig, so I put the old PC in the living room with a table. Now obviously rather than using a dongle, I thought why not just just the LAN? 

I removed the dongle and gave it to a friend. So that's out the window.

 

Now, whenever I log in-

I can see that the lan cable is not detected. I log out, and bam! with no physical adjustment it detected the cable.

But when I log out, and log in again, it loses its connection. I need to log in again, just to get the connection.

 

this is weird and pls dont tell me this is a network driver issue. I thought ethernet cables didn't need these things?

Of course it does. What windows version is this? XP? Older versions of windows might not have the drivers bundled with it.
Newer versions of windows use generic drivers because it works albeit at limited functionality, but then fetches the correct drivers online so it works properly
