iATKOS v7 - network doesn't work with HP 6720s

[grefu]

Hi.
I've got a HP Compaq 6720s laptop with intel platform. I've installed iATKOS v7 on it, with Leopard 10.5. Everything seems to be ok but network doesn't work. Wireless card don't appear and network wired card appear but don't run. I try to configure with DHCP and manually but it doesn't ping to any host.
Could you help me?
Regards.
