So for starters, I have a rather large family and a very slow internet connection due to where I live. Recently I've been having an issue where late at night my internet drastically slows down to the point where it's almost unusable. I figured out that if I turned off my router (Netgear R6900P), everything else that's connected directly to my modem (Actiontec T3200) goes back to normal almost instantly, and as soon as I turn my router back on it slows down again. The only thing I can think of that would be causing this issue would be automatic iPhone backups. I'm wondering if there's a way I can block these from happening through my router rather than going on every single device that my family has connected. Thank you for the help.
