Network Card can't get IP from DHCP server
 

I used FC3. Installed FC3 success. LAN Card can get the IP from DHCP server. When I update & upgrade the patch and to 2.6.10-1.737_FC3 version. my LAN card can't got IP. always auto disconnected.

How can to solve this problem?

what do u get for running

kudzu -p

lspci

and

ifconfig

I key in 'ifconfig eth0'
I get normal information but no IP display. the eth0 is still disconnected

I tried two PCs (Notebook & Desktop). the result are same.
I can not to connect and to get IP when I first connect successfully at 2-3 seconds

what do u have in

/etc/sysconfig/network-scripts/ifcfg-eth0

regards

Have a look at /var/log/messages

You may have entries like "insufficient DHCP reply"
If that is the case, the update requires more fields in the dhcp reply
and you have to add them to dhcp.conf
This is quite a guesswork because dhclient does not tell you which fields are missing.
