Over the past 2-3 days, our "Main" Deco M5 would stop working and would display a solid "Red" light where it is normally a solid "Green" and all network functionality stops working (even local machine to machine connectivity). If I unplug and plug it back in, all goes back to normal. There are a total of 4 Deco M5's and I only have to unplug the main unit to get it going.
I took the latest firmware a couple weeks ago but it seemed to be stable after that but not sure if related. I haven't swapped the main Deco out with one of the others yet, getting ready to, will also swap it's powersupply with another (using stock PSs that came with them).
Anyone else having an issue like this post firmware update?
