DNS Server Isn't Responding When Running Windows Network Diagnostic

I have "Xtreme" internet service with Time Warner Cable, and it isn't so Xtreme. The modem/wireles router is the Ubee DDW3611.I was doing some work earlier this morning, and the lawn mower guy was here in the back doing his thing. All of a sudden the internet goes out. I see that damn dreaded yellow exclamation mark in the taskbar superimposed over the wireless internet icon. My first thought was that the lawn dude ran over some wires.I went outside to see if any wires were exposed or had been damaged. I noticed about a yard of wire was exposed above ground, but did not appear to have any damage.Anyway, I've been trying for the past few hours to fix this darn thing (before the technician gets here around 4pm). I've tried all the simple stuff like reset the modem, restart, mess with dns settings, but I have no idea where to go after this.

Here is what I get when I go to cmd > ipconfig /all:
