I have the same issue with my 5 new E9+, that i have recived yesterday. I have 2 E9+ recived in December and they work fine. But with this 5 i have became crazy. Their default ip is 192.168.80.140, I configurate my router's ip as 192.168.80.1, using network scanner i see that when i power on E9 it is visible in network for one minute and then red light becomes to blink and e9 lost. the same issue with all 5 e9. I cant understand what hapens.
