I've got an old Netgear router model DG834GU whose settings I'd like to change. We've got a working internet connection through this router (the router itself is connected to another router). But for some reason I fail to access the router to change settings (name, password, etc.).
I tried several things, as suggested by How do I log in to my NETGEAR home router? or Unable to access the router web interface: Router login page cannot be displayed or is blank.
That is, I tried to connect to open www.routerlogin.net, www.routerlogin.com, http://192.168.0.1, and http://192.168.1.1. The first two websites resulted in the strange error message
You are not connected to your Router’s WiFi network. To access routerlogin.com, your device must be connected to your Router’s WiFi network. Check your current connection and try again.
Of course this is not true, because I can access internet through this very network.
I tried all the above with and without cable, through an Android Smartphone, Windows 7 and Ubuntu 14.04. What else can I do to speak to my router?
nmap -p- 192.168.1.1
and trytelnet 192.168.1.1
if the telnet port is open.
