N66U loosing traffic monitor data

[DogT]

I was trying to keep track of what computers use how much data on my wireless network and it seemed to be working fine for a few weeks. I even was using the USB port (custom) to store the data thinking that if I loose power which happens here I wouldn't loose the data. Well, I didn't check the traffic monitor for a couple weeks and lo and behold last weekend something used 4GB of data in one day according to our ISP, Hughesnet. I have NetWorx monitoring the PC's so it was not them. Only other thing is the Mac and I have to track that with the Asus. Well, I went into it yesterday and there was no traffic data, nada, zippo. It was like it just started over when I looked at it. There were "No Clients" on the Real time tab. I reset the storage to the RAM and today I have yesterday's traffic data and today's. I see there are some files on the USB stick but is there any way to access it or am I just out of luck? That's why I got this N66U but it seems to loose the traffic data all the time no matter if I use RAM or Custom. Is there any way to keep traffic monitor data? Or just watch it every day? I forget sometimes.
