I set in my LAN settings on my HC2 a static ip: 192.168.1.10
After my HC2 rebotted from a power outage for some reason it went to 192.168.1.11 and was set as DHCP.
I again changed it back to 192.168.1.10 with a static ip because my devices wouldn't work when it was on 192.168.1.11.
Then after some time my devices couldnt' access and i realised it had gone back to 192.168.1.11 again which was also the static IP of a camera so there was a conflict and nothing would work.
Hopefully
