I've seen numerous threads about this on Android phones, but no solutions that have worked so far. When my tablet is connected to Wifi the download arrow constantly blinks (orange arrow) about once a second. I din't really care about this until I realized that it was affecting my battery life. The battery lasts about twice as long if I keep it in 4G. There is no phantom network activity in 4G. Some of the phone threads about this problem suggested the following:
Set wifi router to 5Ghz only - no effect
Kill Samsung S suggest - no effect
Look for culprit apps
I downloaded Traffic Monitor and I think I have pegged it to the "system traffic" category but can't get any more specific info. I wouldn't care if it wasn't affecting battery life and I obviously don't want to leave it in 4G all the time. For right now I have it shutting off wifi in sleep mode.
