Try adding the "dynamic" parameter to the definitions of the ntp servers in your /etc/ntp.conf. For example: server 0.fedora.pool.ntp.org dynamic server 1.fedora.pool.ntp.org dynamic server 2.fedora.pool.ntp.org dynamic In this way the servers will be searched again when the network goes up. The output of "ntpq -p" will tell you if the connections are working (wait a minute or two before checking). Best regards. -- Roberto Ragusa mail at robertoragusa.it
