It just sucked 790MB for whatever reason, probably a firmware update, thought I had all that automatic stuff turned off. I was doing so good with my allowance for the month, no longer. Am glad I have my new super duper router though. Saw exactly what did it. ANother hard lesson learned.
I finally decided to do something about not seeing what machine is doing what unless it was just HTTP traffic... Have multiple internet connections, so multiple routers, all on the same network, helps me see who is using how much and where.
