I am trying to add a new router (NETGEAR WNDR3800) to my network that currently only has an existing modem/router combo from my provider. I tried using the following configuration: first modem router configuration However, the in this configuration the WiFi network has no internet.
Once I tried connecting it like so, the NETGEAR router's network worked well: second modem router configuration
So now I have two separate WiFi networks with two different names and passwords. I would like to change the new NETGEAR router WiFi to match the network of the other, but I am unable to actually open the settings of the NETGEAR router (they should be under www.routerlogin.net according to the manual but when I go there it redirects me to a page saying I'm not connected to any NETGEAR routers).
On tutorials online I read that I will need to turn off my main router, connect the NETGEAR router and change the IP and DHCP settings, but my main router receives internet via a phone cable and the NETGEAR router doesn't have this socket. What can I do?
