I have started the orinoco wireless 802.11b pccards on three independant qnx machines. The driver should be mounted well
, but when i tried to ping randomly from one to another, the network somehow failed to work properly. But may work well 
occasionally. I set the orinoco driver like this:" mount -o channel=11,network=dong,mode=adhoc -T io-net devn-orinoco.so
". 
e.g. i could ping thru from 192.168.1.2 to 192.168.1.10, and also ok from 192.168.1.2 to 192.168.1.10, but failed when 
ping thru from 192.168.1.1 to 1.2, and vice versa.

I wonder if it is the problem of adhoc network configuration or any other possible reasons. 

Thanks,
Eric
