I have been experiencing dropout issues for a few weeks now with varying severity (Some days dropout after dropout, other days - only one disconnect for an evening). The system and kernel logs, like every other consumer router on the market, are of little use to the average user - try googling a specific string and finding an applicable answer to decipher what that entry means and you will share my frustration. Routers for sale on the consumer market need to include a plain English dictionary for understanding log output. In the meantime I have sent snippets of my log record in to Ashok who assures me the issue is being worked on. I will give him and the Securifi tech people a bit more time before I begin hollering a bit louder.
In desperation, I "reset" my network (re-ran the wizard, got new network name, PWs, SSIDs, etc, and began re-adding each of my devices to the network, taking a pause at each connection to look at the router logs for a few minutes to see if anything didn't play well with my A+. I got the majority of my devices up and running without dropouts for a while...but then they returned. And I left a bunch of devices disconnected and turned off my 5ghz network (not used much, and trying to limit every variable I can with my limited networking knowledge.
You could try this approach. Maybe you will have more success than I. In the meantime we await Securifi's response.
