inaccessible internet in live FC10

[carolw]

Hi,
I tried to boot FC10 from CD and before automatic logging I already got the following message:
ipw2200 failed to send: system_config already sending a command

Then when I logged, I noticed that I can't access to internet either via ethernet or wireless. I get the following message when try to determine IP address via dhcp:

determining IP information for eth1: dhclient (2949) is already running-existing. this version of ISC dhcp is based on the release available on ftp.isc.org. features have been added and other changes have been made to the base software release in order to make it work better with distribution.
exiting, failed.

What is the problem and what should be done?

thanks,
