DHCP doesn't give right IP

I just got my Linksys WRT54GL wireless router, set it up and DHCP
doesn't get my laptop right IP. Router IP is set to 192.168.1.1 and DHCP
server is enabled (IP range 192.168.1.100-149). I can connect to it but
internet wouldn't work cause it sets my parameters like this:
-IP address: 192.168.0.218 or 217
-Default gateway: 192.168.0.1
-DHCP Server: 192.168.0.200
-DNS Servers: 192.168.0.1
I have ADSL line and modem Sagem 3344. I deleted entry for DHCP on my
modem and it's working in modem mode (no username and password set in
setting). My connection is set from modem to router and then from router
to 2 switches for desktop PCs (I manually set their IPs and internet
works for them without problem). Also tried on other laptop and same
story. If I manually set IPs on wireless adapter internet works with no
problem. At first I thought that maybe if I upgraded firwmare problem
would be solved but it didn't help. I upgraded to Tomato firmware
version 1.10. If anybody has any idea what could be wrong I would really
appreciate it

I suspect that your laptop is getting its IP from another WAP - one with
IPA=192.168.0.1, instead of your intended router. Probably a router
in a neighboring house.

That's not your DHCP server. Try changing the entire Class C network
IP block in case you're getting your numbers from the neighbors.
Something like:
192.168.5.xxx

Hmmmm... You apparently have two DHCP *SERVERS* running. One in the
modem and one in the router. You can do that but if Tomato has DHCP
passthru or proxy DHCP enabled, it's possible for the clients to end
up getting their IP's from the modem instead of the router. Methinks
it best to totally disarm the DHCP server in the modem, and rely on
the DHCP server in the router. The DHCP *CLIENT* in the router should
be unaffected.

OK, so it's not the unspecified operating system running on the client
computers. That leaves the router and the modem.

Try this simple test. Disconnect the modem from the router. Power
cycle the router. Flush the DNS cache on your unspecified operating
system client computer(s). Get a new IP from the router with the
modem disconnected. Does that work? If yes, then fix the setting in
your modem. If not, then there's something goofy in the router.

You can also do some diagnostics using a DHCP tool:

There's also a similar Linux DHCP tool.

Tomato is now at 1.11.

Change the SSID of your router to make sure you are connecting to it
Lots of folks leave the "Linksys" name as the default SSID,
and it looks like you are connecting to someone else's Linksys Access Point.
