I've a cable modem attached to the WAN interface (FE4) of a new 861W. The interface is configured as a dhcp client.The WAN LED does not come on when the router is attached to the modem. What am I doing wrong?

-----------------------------------------------------------------------
Cisco Configuration Professional (Cisco CP) is installed on this device
and it provides the default username "cisco" for one-time use. If you have
already used the username "cisco" to login to the router and your IOS image
supports the "one-time" user option, then this username has already expired.
You will not be able to login to the router with this username after you exit
this session.
It is strongly suggested that you create a new username with a privilege level
of 15 using the following command.
username <myuser> privilege 15 secret 0 <mypassword>
Replace <myuser> and <mypassword> with the username and password you
want to use.

Hello,
Can you connect a workstation to the cable modem Ethernet handoff and see if you are getting an IP from the ISP? If you did not get an IP, then I would suggest you contacting your ISP.
Hope this helps.
Regards,
NT

Yes, the modem delivers an IP to the client.

I managed to plug the modem into the console port instead of the WAN port.
Because it's during business hours, I can't plug the router directly into the cable modem. I have it plugged into our network which has one router on it with the cable modem on the wan side and the 861W on the other side as well as the rest of our network. The 861W is pulling an IP address from the other router and I can ping any machine on the rest of the network from the 861W. I cannot ping any machine from my client computer though, which is connected to the 861W.

Hi,
Generally it sounds like the routing on your 861w might not be configured correctly. You might want to confirm the routing gateway for internet access points to the WAN side IP address of the 861w. I'd think this is the private IP address being assigned by the other router. The 861w should have a route to the outer network and dhcp assigned to be issued to clients connecting from the LAN side of the 861w.
Hope that helps,

Chris,
Can you try replacing the ip address on fa4 with just
ip address dhcp
without the client id and see whether you get an ip address.
Sometimes you need a reboot of the cable modem to achieve the same...
If the above does not work...
Try,
ip address negotiated (If you router supports is)
and see whether this gives you an ip address.
Lets first get an ip address on Fa4 from your cable modem. Once we do that we can move onwards to the internet access part.
