Linksys Wireless-B Router and DHCP

Hi,

I have a configuration question regarding my Linksys Wireless -B
Broadband Router and a DHCP server on my LAN.

What I would like to do is to have computers what are wired to my DCHP
server via a switch continue to get IP addresses from the DHCP server.
I would also like the Wireless-B Router to hand out IP addresses to a
wireless laptop in another room.

I have been trying to get this setup to work but without much success.
I have cable modem access via Optonline.

Before the wireless router, I had the cable modem attached to a hub to
share the computer via the LAN, with DHCP handing out the IP's with no
problem. When I got the router, I took the cable from the cable modem,
attached it to the WAN port on the router and attached a cable from
one of the four ports on the router to the switch.

DHCP was able to issue IP's to the wired machines, but not to the
wireless laptop. I had DHCP enabled on the wireless router, but it
would not issue IP's to the wireless laptop.

Am I missing something or doing something totally wrong. I am running
W2K and WinXP, both professional versions.

Thanks,

David

First of all, why do you want to have a separate DHCP server for your
internal LAN anymore? Why not let the router's own DHCP handle it all for
you, now?

Now, in your previous setup, are you saying that all of your computers were
attached to your cable modem through a simple hub? That would mean that all
of your computers were attached directly to the cable modem and therefore
connected to the Internet directly. How many computers do you have in your
personal network?

If you've disabled DHCP on the router to the wired network, then you've
disabled DHCP to everything, including the wireless network. Your old DHCP
server won't be able to issue IPs to your wireless router, since it has no
physical connection to that network. You really should let the router handle
your internal DHCP needs from now on.
