I do not have a Note 7. Unfortunately, I'm still on my LG 4. Since I've been on marshmallow, I've noticed that I stay connected to my wifi router, but will lose internet connection. This is mainly noticeable when I'm trying to stream video. I generally keep bluetooth on so my Pebble Time smart watch can get notifications. When I turn bluetooth off, my wifi internet is generally better. At home, I have to occasionally put my phone in airplane mode to get the wifi working better. I've gone into router settings and tried to change to channels with less interference and have tried to tunnel ipv6 to ipv4 connectivitiy. I know 5GHz does not work well on my LG G4. I'm not sure if its a marshmallow thing or an LG G4 thing. I'm trying to decide between a Note 7 and a Moto Z Force Droid edition.
