Thanks Jobeard, and yes, I'm only using the cable or the wifi, but not both at the same time - 1 is always disabled. Though last month I was using both at the same time... which is when my problems started.
I've done the ipconfig /all with the cable plugged in and the wifi disabled. I know my cable is working, because I'm using it to make this post (with the wifi disabled). I'll post the results below. Also, pinging 8.8.8.8 and google.com both came back successful - 4 for 4.
Here are the results from the ipconfig /all:
