Figured somebody here is likely smart enough to provide some insight. I've always been fairly comfortable with technology, but I got into the smartphone game pretty late and on the android side. My wife is a bit less tech-savvy and she likes her iphone...which I pretty much can barely use. Anyways lately it seems like every night when she comes home from work, as soon as her phone connects to the home network everything slows way down. Especially noticable if I am playing a game. We've had this problem in the past and I was able to fix it by upgrading to a better modem (more bonding channels and fully compatibile with our broadband) which allows up to see an honest 80 megs down and well I forget the upstream. I also upgraded to a dual band router (WD N750) and run all mobile devices on 5ghz with all computers on 2.4ghz and the smart TV is hard wired. This resulted in fantastic internet speed and service... until now. Like I said, when her iphone comes home at night the network goes to poop. Doesn't happen with the teenager's iphone. Is worse if she leaves multiple apps open, and seems to be worse when plugged in on standby. I understand about the icloud service, but when my diversified wifi and high speed broadband I just can't believe it would slow everything down THAT much. Any ideas on what settings to look at or other tweaks or solutions?
