[kamila]

On WRT1200ac v2 I've installed 1.10 gargoyle
I've tried configure openvpn to have access to local network
After one try router works but I can't access to panel on 192.168.1.1
even I can't ping 192.168.1.1 from network
I've tried 30/30/30 to reset to factory but it did not work
How can I reset to factory
