I have had these 3 Devo P9 units for a little over a month now, and they worked fine for the first week or so. After that I began suffering wireless disconnects throughout the day. All wireless devices lose connection, but all my wired devices remain fine so I know its not my ISP messing up. I read online to turn off the 5gz band and when I did that, the connection remains completely stable... but now im stuck on slow 2.4. I would really like to be able to use 5gz considering I paid all this money for these devices. When I turn on 5gz now it will work for a few hours or even a whole day, but evetually the drops start again and the only solution has been to turn off that band. Has this issue been observed before and is there a fix?

My Decos are set up in router mode. Main deco connected via ethernet to my modem, two other downstairs are wireless. The LEDs on main deco are NOT red when the drops happen, and as stated before wired connection is still working fine during the drop periods. I am in the same room, maybe 15 feet away from main deco so I'm definitely close enough for 5ghz connection.
