Hi!

i installed Sugar 0.84.2 on a stick (beta) according to instruction in http://wiki.sugarlab.org/go/Sugar_on_a_Stick ; i have an old machine  and so i had to use the "Boot helper" CD.

My question is: how to configure mesh network? I don't see msh0..

[root at localhost /]# ifconfig -a

i have nx9005 with chipset atheros 5414.

I try to explain better .. to configure a mesh network i keyed:
iwconfig wlan0 mode ad-hoc essid mesh-olpc channel 6
ifconfig wlan0 192.168.3.8
but
mesh's channel changing and so when i ping the other machine i lost a
lot of ping because of changing channel.. the machines are't 
synchronized..
Also when i keyed iwconfig don't see ESSID (it's blank).. it stays ESSID:"mesh-olpc" only few seconds!!  

What's wrong? I forget something? 
it's a driver's problem?! when i keyed "iwpriv" returns "no private ioctls".. i use atheros e not marvell..
What can I do?

Thanks!

Alessia
