I'm having a problem with one of my Deco P9 units. I've had the setup for about 2 months. 2 of the units are fine. 1 of the units has an issue. Ever since I've had it, it blinks red once a week and needs to be unplugged and reset. It's annoying, but up until now it's been manageble. It's now happened 5 times in the last 2 days - 3 times today so far in the span of 2 hours. It's always the same unit, but it's disruptive to have to constantly reset in order to have wifi. can anything be done about this?
