Wirelsss Network Not Connecting

[Schiz0]

Hey everyone,

I recently installed Ubuntu 7.10 on a Gateway laptop. The wlan0 IS
displayed in ifconfig - so it was detected. The wireless network I'm
trying to connect to is also detected, but it seems that I cannot
connect to it. The details are as follows:

DLink Router
SSID _IS_ broadcasting (AKA, it's not a hidden network)
Using WPA-Personal (Not WPA2)
DHCP enabled

The problem is, Ubuntu seems to connect, but it is using the wrong
information. For example, the DHCP range in my router config is set to
192.168.1.100 to 192.168.1.199, with a netmask of 255.255.255.0.
However, when Ubuntu tries to connect automatically, ifconfig shows
that the IP is outside of that range, and the netmask is different. It
is also using the wrong gateway IP. In Ubuntu, I set it up to use a
Dynamic IP using DHCP. I'm not sure what I'm doing wrong. I've never
set up a linux on a wireless laptop before.

Thanks for the help,
