WLAN connecting problem

hello

I have this problem :

I have 2 laptop, 1 wlan pcmcia card and 1 wlan access point.

With my first laptop, everything is ok

The problem is with my 2nd laptop. When I connect the same Pcmcia Card on
this pc, it sees the network, but he receive an adress IP that is not on the
range of the network !? even the subnet mask is not the one of the network
the one it get : 255.255.0.0 - the subnet mask of the network :
255.255.255.0)
The wireless Lan SSID that it recognize is the correct one.

Both laptop are in winxppro sp2

Does anyone have an idea ?

thanks a lot for your help.

Eric
