I just got this router last week.  The wifi periodically drops out for a few seconds, then reconnects.  I use the smart connect option.  I have 17 devices connected, most show they are connected to the 2.5ghz.  This only seems to happen with the devices connected to the 5ghz.  For example, 2 iphones and a kindle fire.  We have multiple Amazon echo dots and smart plugs connected to the 2.5 ghz that don't seem to be affected. My ISP is Comcast Xfinity, and I have the 1gb internet plan.  

Here is my most recent log.  It appears that when the wifi drops, the log says "Lease host name not found".
