Ok it's looking better now and the wireless channel, signal strength and encryption looks good so no problems there.
The only possible problem I see now is that your ipconfig is suddenly showing the Ethernet connection as connected by not getting anything from the router where before it didn't show up at all, or maybe it was accidently left out of the ipconfig? I think maybe the bottom of the wireless connection was left out in the ipconfig and the last part of the Ethernet connection was showing on the next ipconfig which confused me.
Can you go into Device Manager and disable the Ethernet connection just as a test.
Do you have iTunes installed on this system?
