Let me clarify. I live in an apartment building where the various Internet Companies have their cables powered out of 1 Locked Boxed Area. I am on ATT U verse DSL. I am connected in my apartment by a Router/Modem. I recently bought a portable electric generator that stores 6 hour of electricity. Should the power go out in my neighborhood (which happens for short periods of time several times a year) and I connect my router/modem to my portable emergency power, will I still be able to get the internet during the outage through ATT U Verse (assuming they are operating) or will it not matter because the Cable Power Box for the Building is still powerless? I apologize if this is sounding convoluted.
