So last week all of a sudden I lost connection to my wired connection, I ended up re-installing the driver and it worked again for a little while. However the same thing happened again and when I try to re-install now an error occurs that looks like the picture below.

Now I am not sure how to install it. I can connect wirelessly but currently my student dorm only have wired connection and have to be at school to get online. When I go into the device manager I can see the driver but it has a yellow exclamation point. And when i go to the properties I get this message:

 Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)

If anyone knows how to fix this it would be greatly apprecaited.
