I installed 6 of these routher connected to a TP link switch since i am powering them through with PoE. Everything was working well for about a week, all of a sudden two of my routers stopped comunicating with the app. On of them displays a red light while the other shows no light. I check the connection from the switch to both of them and everything seems to be fine yet they still aren't functioning. I tried deleting them from the apl and reseting them to be able to pair them again but now, the routers display the blue flashing light but the wont pair with my deco app (the app doesn't find the router*). I already deleted the app and downloaded it again, I tried rebooting the system but i get a connection error, I tried updating the firmware but i get a connection error. The other 4 routers are working fine.
