Samsung S8+ Causing Internet to drop

[blakeyshoebasket]

Hey guys, this is my first post here so go easy on me please.

So basically we have been having problems with my ADSL2+ internet connection, i was noticing that my phone was causing the internet in my router to drop or slow down to EXTREMELY SLOW to the point where i get 1300+ ping in games. im quite confident that it is the phone because i have been using my 4g phone data for the past couple of days and there has been no drop outs but as soon as i connect my phone to my home WiFi it starts acting up within 5-10 minutes to about 1.5 hours after i connect it. i also called my ISP and they had nailed it down to apparently their are high Upload speeds coming from the phone but i checked the usage on the phone and there doesn't seem to be anything uploading, even in the background.

Things iv tried:
Changing wireless channel on my router.
Changing from 802.11 b/g/n mixed to 802.11n.
Tried making the phone forget the Router and reconnect to it.
Turned the router off and letting it sit for 5 minutes.

none of them seem to have worked and im so confused and id love a helping hand.

Thank you

On the phone, in settings/connections/more connection settings, do you have Download booster on as it uses Wifi & Data at the same time? that might be cause?

I only have an S7 Edge and I assume you are on Android 7 still?

That seems odd, would have thought Router would share signal between all devices and not let one have too much.
