Before removing and inserting the card back: Time out on getting the IP from 
the DHCP server.

After:
[root@localhost sforbes]# ifup eth0
Determining IP information for eth0... done.
dhcpcd.exe: interface eth0 has been configured with old IP=192.168.2.100

See above. Also, the light correctly changes from 10mb to `100mb

>what are the logs showing ? 

In which log exactly should I look? (yes, newbie question. Didn't see anything 
obvios in /etc/logs )

>maybe something causes the network module to unload ?

But even so- why does it not reload properly?

>do "lsmod |grep modulename" in the morning

Wasn't sure about the module name that I was looking for, so I did a general 
lsmod:
[root@localhost sforbes]# lsmod

Works fine

Doesn't work (host unreachble)

Doesn't work :-(

Any more ideas?

Thanks again
