hello guys, I have a with a problem with my Residential Gateway (DIR-615) or maybe with the BTU. Last night I accidentally turned off my main switch and after that I try to restart the whole thing and  connect to the Internet but can't. On the RG, the "Earth symbol" light is always colour "Orange" and the "Wave symbol" light is turned off. Usually both of them will be "light green" if there's no problem.
Please advice and thank you

Orange earth line means PPPOE connection fail.. Most probably their server, unless ur router corrupted the username & password. Sometime happen after power on & off.

Try re-entering unifi password in the router.
