I used a Stage 3 install of Gentoo; been having issues with dhcp over a period of 3 re-installs.
DHCP worked fine on my first install on the base Gentoo system, but somehow it stopped working and I re-installed in an attempt to correct it. I have read over the manual several times just to make sure that I wasn't leaving anything out.
I emerged dhcpcd, and I have /etc/conf.d/net set to config_eth0=("dhcp"). I have checked to make sure that this is the correct NIC using "lspci -v" (I have two) and it is. This is not a wireless connection. I am sure that my network is configured correctly; there have been no network changes since the original working install of Gentoo.
Upon boot, Gentoo runs net.eth0 and dhcpcd, but fails to receive an IP address. I also get the error that "netmount" has failed to start.
Everything else is working correctly except my dhcp; it's driving me crazy especially since it has worked before, but refuses to now. This leads me to believe that it is a network problem, but there have been no changes to the network.
The network is MAC restricted, but my MAC address is ok because I can boot to Windows and connect.
I really need some help.
EDIT: I forgot to mention the kernel. I used genkernel as well as coldplug, and coldplug has been added to the boot runlevel. My NIC is a standard Broadcom NIC that has worked with other linux distros in the past.
