Deco S4's not choosing correct source unit and devices not choosing best signal in mesh mode
I've read a bunch on the topic of deco's connecting to the main unit instead of the next nearest unit. I've also read that this is fixed in 1.6.x firmware. Mine are on 1.5.1 and say up to date. Is this 1.6 firmware going to be released for S4 models or not?
Also my gaming pc is connecting to the main instead of the nearest deco as well and I don't know how to make it switch. If I turn off the main unit I'm assuming it'll switch, but then it switches back as soon as main unit is back on. I can't turn off the mesh setting with it connected to a closer unit because the iphone app won't let me see connected devices when the main is down.
Here is a diagram of my house. My main unit is in the basement, used as a router plugged into my modem. I have a two story house with a basement so I set it up for 3 story plan. My second unit is on the main level living room, not directly above the main. My third unit in on the upstairs, is also not directly above the main, it's actually more vertically aligned with the second one and of course closer being on a closer floor.
How do I fix this?
