Meanwhile, I'm not exactly sure how those routers "identify" themselves, but I have a
guess.
I "THINK" the router's switch port has a MAC address. And that's probably why it's
causing
a problem. RoadRunner identifies machines on it's Cable network via MAC address.
When you
had your machine set up, they found out what your MAC address was, then programed the
modem
and the DHCP server to accept traffic from that address.
Well now you've introduced something else to get an IP address. So your router goes
on
says "I'm <MAC> address, give me an IP address." The DHCP server then goes hi <MAC>
address. Nice to meet you, but I don't know who you are!" Then doesn't give an IP
Address.
So when you remove that one link, and go directly through the cable modem, your machine
does the same thing. But the DHCP server goes, "AH!! I know who you are. Here's
your IP
address."
What you'll most likely have to do is find out what the MAC address for the router is
and
then contact Comcast. (Or whom ever's reselling RoadRunner there. Here in Michigan
it's
Comcast.) Let them know you need to change the MAC address they recognize. Even
explain
the situation to them if needed. When I ordered two new IP addresses he told me I
could
just buy a router and save money, so I'm sure it's acceptable through their eyes.
But again, I don't know how those routers identify themselves. So they may not
actually
have a MAC address. But that sound like how it's done, and that would make sense why
you
can't get to the outside world.
Hope that helps, and I hope I'm right! lol ;0)

| First of all thanks to everyone in advance, and I apologize for the long
| post!
|
| I am unable to connect through my router to my cable modem. I subscribed
| last week to Road Runner service here in the New York City area. In order to
| set up a quick LAN I purchased a Netgear RT314 Gateway Router and 2 NIC
| cards. I have 2 computers on the network; my wife's Win95 machine and my box
| dual booting Win2K and Mandrake 7.1.
|
| On my pc in Win2K everything works fine obtaining IP and DNS addresses
| automatically. And in Mandrake when I connect the cable directly from my
| Netgear FA312 NIC card using dhcp, to the Toshiba DOCSIS PCX1100U cable
| modem, that works fine also. But everything fails when I plug into the
| router. Pump fails on boot, and also fails if I try to activate the card in
| the Network Configurator control-panel. I have tried to set the IP address
| manually and specifying a default gateway:192.168.0.1 (my router) but with
| no luck. I am not even able to ping the router.
|
| I have searched and looked at every posting, archive and FAQ I could get my
| hands on and cannot figure it out. All the ones that I have seen address how
| to connect directly to the modem, not through a network. (Big thanks to the
| Linux Road Runner HOW-TO Web site, and to Donald Becker for writing the
| natsemi.c driver that got my FA312 card working!) If anybody has any ideas
| or suggestions or url's that would point me into the right direction it
| would be a great help.
|
| Here is my configuration info from Network Configurator;
| NAMES
| Hostname: jdowns (my account name)
| Domain: nyc.rr.com
| HOSTS
| IP: 127.0.0.1
| Name: localhost.localdomain
| Nicknames: localhost
| INTERFACES
| Interface: lo
| Ip: 127.0.0.1
| proto: none
| atboot: yes
| Interface: eth0
| Ip:
| proto: dhcp
| atboot: yes
| DEVICE: eth0
| Ip:
| Netmask: 255.255.255.0
| Activate at boot time
|
| This is the configuration that works when I plug directly into the cable
| modem.
|
| Again sorry for the long post, and many thanks to everyone!
