Nighthawk App tells me i am online and things like the Facebook App for example load with a bit delay. (too long for an 100 mbts connection) Orher funkctions like Google won‘t load. Been searching threw a lot of posts, but can‘t find a proper solution. Sorry for my bad english and thanks for every answer. By the way, the in App speed test also tells me 0 mbts.
the vigor165 is a modem/router combo device. It puts you in a double nat and can cause multiple issues. You can try putting the vigor in modem only/passthrough mode or you can try putting the netgear in access point mode. either solution would fix the issue of multiple routers in router mode on your network. There's also the option of putting the netgears IP address into the vigor's dmz.
