Configuring Netgear MR814 to work with cable modem

Can someone help me figure out what I'm doing wrong? I am running
Windows XP Professional and until last week had a DSL connection with
a Netgear MR814 wireless router. I had a PCMCIA wireless card for my
laptop which enabled me to access the other PC as well as surf the
web.

Last week, I switched from DSL to cable and I have not been able to
get the combination working. I CAN get it working directly (ethernet
cable from PC to cable modem). As soon as I change that (ethernet to
internet port on router, ethernet from first free port on router to
pc) it doesn't work. I have configured the LAN for DHCP (as the cable
provider says I must). Also, told it to sense IP address
automatically. I THINK the router needs to be re-configured but I
don't know how to since it requires an internet connection to do so.
Netgear says to type 192.168.0.1 in any browser window to get to the
configuration settings BUT that gets me nowhere without an internet
connection.

Any advice?

 

I've used a combination of a Netgear MR814 and had some trouble with it. But
with perserverence I find you can get the router to respond on URL
192.168.0.1 However it tends to be flakey. I find that changing the user
name and the password doesn't necessarily seem to take. And it does not have
to be connected to the internet (in my case SBC DSL) to access the router.
Also the test mechanism does not seem to work on my router. But you can leave
the router setup and try pinging something live. It seems to connect without
the router letting you know all the time. I find it does not disconnect but
it does strange things. I've had a real trouble getting three computers to
network with this setup (one XP, two MEs with one of them wireless.)
