What you are experiencing with your router is strange, to say the least. We're sorry for the inconvenience, and would like to provide some assistance and rectifying.
It is possible that disconnects happen with some power fluctuations, however, if the cause was a power fluctuation, it would happen once in a blue moon, rather than 3+ times a day. We would like to investigate on what is causing these drops, and if needed, to replace the unit so you are provided with a stable connection you can rely on.
