Hey all, 

Have the wifi 7 deco, B85.  I would say the two decks are roughly (through walls) 50ft apart.  My Wi-Fi mapping is terrible. 

First image is connected to MLO, walking from office to living room, you see so much of a dead zone, I always lose connection.

This second photo is on 2ghz and while it's better, my phone doesn't switch to the second deck even if I'm right in front of it.

Any settings I can change on the deco itself or devices?  It's driving my crazy, these things are supposed to cover 3000+ sqt ft and I get bad wifi on same floor
