After a relatively easy setup yesterday, I came home after a night shift to discover the main deco unit was flashing red. I figured a quick restart would solve the issue.
Alas. No matter what, the unit would not restore itself to a functioning state. So I went to bed, hoping to fix it after some sleep.
After waking up, find that all the Deco units (all set up in AP mode, like th main deco) have the same issue.
Eventually, I resolved this by removing the network and starting setup over completely.
So far so good.
Except for one unit. The initial main Deco. This unit will start off with a solid yellow light. Then transtion blinking blue, on to solid blue and then turn off and go back to yellow. It is invisible to the network, a direct wired connection fails as well. The unit cannot be accessed via direct connection (188.8.131.52) and what is far,far worse: it is entirely unresponsive to the hardware factory reset button on the device. The button does nothing. Neither when pressed,held down or held down before powering the unit on.
If not, I will simply return this set and never look back.
