Below is the information you asked for. I don't know what it means. But, I notice in /var/messages it says "ip_tables" (even though I have the firewall disabled). And, something about an unknown hardware address type(?) The network card is a Netgear FA310tx (it worked fine in FC1, RH9). The router is a Linksys BEFSX41. I upgraded the firmware tonight after this problem started with FC2. It didn't fix the problem. /var/log/messages (I have removed the timestamp and "localhost" prefix from each line.) ============>>>>> kernel: ip_tables: (C) 2000-2002 Netfilter core team dhclient: sit0: unknown hardware address type 776 dhclient: sit0: unknown hardware address type 776 kernel: NETDEV WATCHDOG: eth0: transmit timed out dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 8 kernel: NETDEV WATCHDOG: eth0: transmit timed out dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 8 kernel: NETDEV WATCHDOG: eth0: transmit timed out dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 21 kernel: NETDEV WATCHDOG: eth0: transmit timed out dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 20 kernel: NETDEV WATCHDOG: eth0: transmit timed out dhclient: DHCPDISCOVER on eth0 to 255.255.255.255 port 67 interval 4 dhclient: No DHCPOFFERS received. kernel: NETDEV WATCHDOG: eth0: transmit timed out /etc/sysconfig/network-scripts/ifcfg-eth0 (Most of the values below are from when I tried a static IP.
