Past 2 days I can't upload video files from my external to Dropbox via Mac book. ANYBODY?!?! File loads to 9 - 10 minutes left; stops. Says I've lost internet connection; will resume loading when I RECONNECT. Refreshed modem & router; still won't work. Intermittent internet signal. Goes from WIFI CONNECTED to LOOKING FOR NETWORK. Tried uploading wired to internet too; same thing. First time having this problem. HELP!!!!
