I've just installed FC5 from cdrom isos onto a Dell D810. I have looked through quite a few threads but nothing I've seen...and tried, has resolved the issue. Essentially eth0, a BCM5751 using the TG3 driver, goes active but it appears DHCP or DNS, or both?, isn't working. I've checked network manager, as seen on several threads, and it looks to be active.
/etc/sysconfig/network-scripts/ifcfg-eth0 reads as follows;
/etc/modprobe.conf reads as follows;
alias eth0 tg3
alias scsi_hostadapter ata_piix
alias eth1 ipw2200
alias snd-card-0 snd-intel8x0
options snd-card-0 index=0
options snd-intel8x0 index=0
dmesg has some interesting text relevant to eth0 it reads;
eth0: Tigon3 (partno(BCM95751) rev 4001 PHY(5750) (PCI Express) 10/100/1000BaseT Ethernet...
tg3: eth0: link is up at 10 mbps, half duplex
tg3: eth0: Flow control is off for TX and off for RX
ADDRCONF(NETDEV_CHANGE): eth0: link becomes ready
eth0: no IPv6 routers present
the previous series of messages starting at tg3 repeats.
I looked at /etc/resolv.conf but the only thing in it is a comment that reads as follows;
# generated by NetworkManager, do not edit!
I have not tried static addressing which I would prefer to avoid if possible.
Ethernet controller: Broadcom Corpporation NetXtreme BCM5751 Gigabit Ethernet PCI Express (rev 01)
I also have a Intel PRO/Wireless card at eth1 but I haven't tried to do anything with that. It does not go active at boot.
I'll be glad to provide further info as needed and I appreciate any help provided.
