Linksys Wireless-B Router and DHCP
Posted by DavidNoack on December 18th, 2003


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

I think the problem is you have two DHCP servers at the same time.

As a test, use only the DHCP server in the router and disable the other one
you have. This should give you both wired and wireless.

The next test is to disable the DHCP server in the router, and enable the
other one you have. This too should give you both wired and wireless.

Try using an access point instead of a router. I had much the same issue
when I tried to hook up a wireless router to one of the ports on my wired
network. Even though I disabled the DHCP settings on the wireless it would
not work. Just for the heck of it I got a wireless access point, Linksys
WAP11. Worked right out of the box! Setting up the security for wireless
took another 10 minutes.
