HNS was setup and initiated only today. After the technician left, I set up my Buffalo WHR-HP-G300N router. Every now and then, the HNS login page opens up instead of a website. The internet's disconnected at this point, but it starts up again the moment I enter my ID and password.The Connection Type on "Continuous Connection". Tried with both ON and OFF on "Keep Alive". After almost an hour i need to login again. This shouldn't happen since the PPPoE is setup on the router with these settings.Any clues as to what could be going on?
