problem configuring NETGEAR modem/router

[regsim]

Hi,

I use Ubuntu 9.04 Jaunty Jackalope.

I have been trying to configure a NETGEAR DGN1000 modem router.

my manual says that to access the modem for configuration, I should

"Type http://192.168.0.1 in the address field of [my] browser, and then click Enter."

my browser, though, does not seem to find any such page and so I cannot continue the configuration.

btw, we had no problem configuring another computer in the house running on windows vista, so that it looks like the cables are all in place, the modem and the line are ok.

I ran dhclient and then ifconfig, but i confess that i do not really understand what all this means. I would appreciate any help or ideas!
thanks

here are the results:

... turns out my ethernet card was somehow faulty. i bought a new one and am now struggling to understand how to install the linux driver, but that would not belong in this thread.
