AC2300 frequent short wifi signal drops
Hi all,
I've just installed a new AC2300 router and am having a problem where the wifi signal on my 2.4GHz network drops out for a brief moment -- a few seconds at most -- very periodically, about every minute or so. Here's a screenshot I've taken from my wifi analyzer that covers about 3 minutes of time:
The top two SSIDs are mine, the blue is the 2.4GHz and the pink is the 5GHz. The signal strength is fine (hovering around -50dBm most of the time). There are about 10 devices connected right now, most of them doing nothing (phones and tablets just idling), but I've seen the same behavior with no devices at all connected (I tested this by changing the SSID name so that everything was disconnected at once). I've updated the router to the latest FW (2.0.3, I think), and have tried manually adjusting the 2.4GHz channel and channel width.
Can anyone suggest why this might be happening, or what I might be able to do to further isolate the problem (and hopefully fix it)?
Thanks!
