Metered network

I have used Norton for years and never had any problems. But since last week, I am getting a message that says that "Norton 360 is in economy mnetwork usage mode because current connection is metered and has data transfer limit. Using Windows cost settings." From my research, it appears that this is not a new message, but I have never seen it before. Did something change with an update? I haven't made any changes to Norton or to my wifi network. I looked to see how to make this non-metered,but the instructions seem to be missing some info or  my computer is "different" as the selections don't seem the same. any help on this would be appreciated.
