status of Net work card

Hello all,

I just install qnx 6.4.0 on a new PC and I get a question with the net card. when I insert the cable into the socket the yellow LED on the socket is on, but the green LED no response (another side of the cable is a robot controller). while I try on my old PC the green LED is flushing. and if I use the ifconfig -a command : the result of the new PC is like:

ifconfig

lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33192
inet 127.0.0.1 netmask 0xff000000
en0: flags=80008843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST,SHIM> mtu 1500
capabilities=7<IP4CSUM,TCP4CSUM,UDP4CSUM>
enabled=0
address: 90:e6:ba:53:41:78
inet 192.168.0.16 netmask 0xffffff00 broadcast 192.168.0.255
I noticed there is a line is [color=red]enabled=0, while on my old PC there is no such line but has a line is [color=red]status=active

so,do I need toactive my new PC? and how to do it?
thanks a lot!

try ifconfig en0 enable

enable is a bad value, or I should use TCP6CSUM?
And why every time I restart the PC, the IP address gone, and I have to reset the ip again?

Thank you
