Data usage monitor not working

We have not seen any data in 4 days from the online data usage monitor, which I know is incorrect as we have been using the internet and streaming movies. The last (what I believe) accurate report was on 1/30/15. What I am wondering though is around this timeframe we turned in our emta as we dropped phone services, and went to renting the netgear 3000dv2 Gateway. It seems to be working fine, no speed issues but is there something in the gateway that needs to be turned on? I went in there and looked around but didnt see anything obvious. I just want to be aware of how much data we are actually using.
