Poor connection on multiple clients

unknown

Hello! I'm pretty new to ruckus, and i'm having an issue with poor connection on several clients, I hope you can help me out!

I have a home with 3 unleashed 550 AP's. 2 upstairs 1 downstairs. I am getting poor connection on devices even when just maybe 30 feet away with no obstructions between the device and the AP. and even worse at 10 ft with a wall in between.

I tried setting channels and power manually and that didn't work, so right now I changed power to auto and it's still not working as I would expect, can someone point out any settings/best practices?

Can you validate in the connected client info tab, that the devices that have poor connection, are indeed connected to the closest AP?

It is easier to give the AP's a description that describes their physical location, that way it is easier to see in the connected clients overview.

(there is some delay in the admin panel, you might have to refresh the page sometimes)
