Modem is offline and won't work - Time Warner Internet

This question is about "Modem is offline and won't work", with Time Warner Cable internet and apps. I called spectrum to see what I could do about it and they told me to unplug my modem and plug it back in and all of that stuff. Nothing worked, and on my modem the only lights that are green are the power, Ethernet, and wifi lights. The DS light is solid orange and the US light is flashing orange. The Online light is off completely. Spectrum has an appointment set up for Monday but I wanted to see if anyone on here had any suggestions on how to fix it. My modem is the arris DG860A
