Hello Linux world !

Could someone tell me how to ping between my 2 computers using wireless adapters ?

I thought all was setup correctly as the iwconfig tell me that the two
machines are associated to the same cell :

-------------------------------------- desktopPC -------------------------------------------------------
[root@portal root]# iwconfig

wlan0 IEEE 802.11g ESSID:"bengoFM" Nickname:"portal"
Mode:Ad-Hoc Frequency:2.462 GHz Cell: 02:0E:35:B5:77:27
Bit Rate=54 Mb/s Tx-Power:14 dBm
RTS thr=2347 B Fragment thr=2346 B
Encryption key:off
Power Management:off
Link Quality:100/100 Signal level:-30 dBm Noise level:-256 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:113196 Missed beacon:0

--------------------------------------- laptopPC ------------------------------------------------------
[root@poortable root]# iwconfig

eth1 IEEE 802.11g ESSID:"bengoFM" Nickname:"poortable"
Mode:Ad-Hoc Channel:11 Cell: 02:0E:35:B5:77:27
Bit Rate=54Mb/s Tx-Power=20 dBm
RTS thr:off Fragment thr:off
Encryption key:off
Power Management:off
Link Quality:41/100 Signal level:-42 dBm Noise level:-256 dBm
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:4 Missed beacon:0

Here are my configurations:
The two computer uses Fedora core 2.

1) My desktopPC has got a
Linksys WMP54G rev. 03 ( BroadCom BCM94306 chipset )
working with the ndiswrapper 0.10 driver

2) My laptopPC has got an integrated
Intel PRO/Wireless 2200BG rev.05
working with the ipw2200 driver
-----------------------------------------------------------------------------------------------------------------

I typed on each respectively:

ifup eth1 ( on the laptopPC )
ifup wlan0 ( on the desktopPC )

It gave each a static IP, as stated by ifconfig:

-------------------------------------- desktopPC -------------------------------------------------------
[root@portal root]# ifconfig wlan0

But I can't even ping:

[root@portal root]# ping 192.168.0.10
