wireless last stand

edit

I have a working wireless network under ubuntu 10.04 that I'm trying to duplicate on a more recent linux distro. I've tried quite a few so my difficulty is lack of knowledge, not the distro's themselves and networking on the latest distro's seems to be set up differently than most of the tutorial type documentation available. Anyway, I've decided to ask for help and take my last shot with fedora 18.

Here's the setup that works under ubuntu:

Desktop PC (Ubuntu 10.04 with firestarter configured firewall)
    eth0 automatic DCHP  (connects to cable modem)
    eth1 static  192.168.0.1   255.255.255.0       0.0.0.0  (unused)
    wlan0        192.168.1.1   255.255.255.0   192.168.0.1  (adhoc network WEP)
        dns 207.69.188.185, 207.69.188.186
Dell laptop (LinuxMint 14)
    wlan0        192.168.1.2   255.255.255.0   192.168.0.1
Dell PC (Windows XP)
    eth0         192.168.0.3 (turned off)
    wlan0        192.168.1.3   255.255.255.0   192.168.0.1

ckasso@507gr:~$ sudo route -v
Kernel IP routing table (ubuntu)

192.168.1.0     *               255.255.255.0   U     2      0        0 wlan0
192.168.0.0     *               255.255.255.0   U     1      0        0 eth1
link-local      *               255.255.0.0     U     1000   0        0 eth1
default         user-160u0g1.ca 0.0.0.0         UG    0      0        0 eth0

With fedora I can access the internet from the desktop only and I can ping back and forth between the desktop and laptop.

I don't understand what the routing tables are telling me except that I think that is where my problem is. Can someone shed some light or point me to something that would help?
