All, As a continuation of the disc controller failure/system rebuild, I have the new box built and a pair of fresh drives waiting for a new Arch install. This motherboard has the Realtek 8111/8168/8411 chipset. (Gigabyte GA-990FXA-UD3 motherboard). I am booting with the latest install medium which boots fine in legacy or EUFI mode. No matter what I do, I cannot get an IPv4 address. I have read: https://wiki.archlinux.org/index.php/Network_configuration#Realtek_no_link_.... (that's not the problem, link light is on, activity indicator is flashing, and link is reported 'Up' by 'ip link') I have read: https://wiki.archlinux.org/index.php/Network_configuration#Realtek_RTL8111.2... - installed (pacman -U r8168-8.040.00-5-x86_64.pkg.tar.xz) - blacklisted r8169 - loaded r8168 - confirmed the NIC is using r8168 w/lspci -v - systemctl restart dhcpcd (many times) - systemctl status dhcpcd reports no IPv6 Routers no IPv4 Leases request timeout It's not the cable or my dhcpd server, I boot the box with the failed disc controller, and it is assigned an address just fine. (same cable) I'm stuck, looking at the log on my dhcp server, the requests are never seen. It's like the card isn't sending, but the link light is fine and the activity light on the NIC is flashes when it sees traffic? What else can I try? -- David C. Rankin, J.D.,P.E.
