networking with ethernet and wlan in my box

Hi,

I have a linux box running Linux kernel 2.6.12-18mdk Mandriva 2006
In it I have had a pci lan card for some time. It connects to the internet via my adsl
modem/router.

I have just put a wireless pci lan card in it as well.

I have a firewall at my ISP and on the modem/router so, as a temporary measure and to make
sure it didn't interfere with any connection attempts I disabled it on my Linux box.

I now have an old laptop with Win9Se and vector linux kernel sata-2.4.29 on it.

I have put a wireless lan card in it and am at present trying to get the laptop to connect
to the linux box and have access to the internet.

I am struggling as the laptop cannot connect properly.

For the linux box:
To start with I had a static ip address 192.168.1.100 for the eth0 card

and tried 192.168.1.50 for wlan0 card in Ad-hoc mode

On the laptop:
to start with I have tried to configure windows to connect.
The card was given an ip 0f 192.168.1.70

The software was configured to connect and found the wireless lan. It seemed to find the
linux wireless card with no trouble and connected to the wireless lan but that is all.

Ping got no replies and no site could be found either by name or ip address.

I then decided to set up dhcpd on my modem/router and set up both boxes to use dhcp
Addresses were assigned but I still can get no further.

/sbin/ifconfig shows:

I am by no means an expert at this so wonder if you guys can point me in the right direction?

All sorted,
Needed wlan0 on different subnet to eth0.
Set laptop Ip address in same range as wlan0 card
with gateway ip address to that of wlan card.

then used Mandriva Control centre on main PC to allow internet sharing.
Now all seems to work

ifconfig :
