OK, the result for 24hrs proved it the offending app was the Google Drive Sync as it was trying to sync an old work folder which was not needed anyway. I added 1Gb and it was consumed in 24hrs after exiting the sync app.. Still way high for my type of usage (I do a moderate amount of research but do not stream music/video exc. for an occasional news item). Of note is that I have worked from home for many years, always via satellite before retiring with all resources and systems being IP based. I went from WildBlue to 3G in one location and then to DishNet and now HughesNet in this location. What is curious is that when I began service with HughesNet my consumed bandwidth more than doubled, immediately, with all things being equal exc. that now being retired I am not at my desk for 8+ hrs a day and no more skype calls, web prezos, SFDC, etc. My usage s/b at its lowest.
I have chalked this up to be a difference in the way bandwidth is measured with HughesNet vs. with the other providers. I'll continue to keep and eye on this issue.
Thx again, all, for the assistance.
