My card:

After doing pacman -Syu, ethernet on my desktop stopped working. The card on my laptop is the same, at least according to lspci, and is working fine.
When I upgraded, there was a change in syntax in rc.conf for defining the network, but I'm just attempting dhcp for now before I try to set up a static ip:
interface=eth0 address= netmask= gateway=
I've tried resetting the router and switching from the kernel's r8169 driver to the r8168 driver from the aur. I compiled the aur driver on my laptop and transferred to the desktop on usb -- as long as they're both x86_64, this shouldn't be a problem, right?
Regardless of my choice of driver, ethernet on the laptop works fine, and doesn't work at all on the desktop. If I set up ethernet manually using ifconfig to define the address/netmask/broadcast/etc (making sure the routes are correct), everything appears to work fine until I try to ping the router and get "Destination Host Unreachable".
And the kicker is that the light on the router for the port I have my ethernet cable plugged into will light up for the laptop, but not the desktop. Given this and the other behavior, I'm inclined to think it's a hardware issue, but this hardware is only several months old, and having this happen right after an upgrade seems unlikely to be a coincidence. Anything else I can try short of reinstalling or getting a replacement from the manufacturer?
I'm using netcfg, and haven't found problems so far with all changes... The daemon is net-profiles, and you can copy the example for static wired profile into a valid profile, and setup rc.conf accordingly.
See:
How odd. Every other method I've tried for setting up a static IP succeeds (but doesn't actually get me a working connection). Netcfg gives me this: root@bender:~# cat /etc/network.d/ethernet CONNECTION='ethernet' DESCRIPTION='Ethernet' INTERFACE='eth0' IP='static' ADDR='192.168.0.120' GATEWAY='192.168.0.1' DNS=('192.168.0.1') root@bender:~# netcfg ethernet :: ethernet up [BUSY]
No connection
[FAIL] root@bender:~# Doing 'sh -x netcfg ethernet' shows that it's printing 'No connection' from '/usr/lib/network/connections/ethernet up ethernet' on this snippet: if ! checkyesno "${SKIPNOCARRIER:-no}" && ip link show dev "$INTERFACE" | fgrep -q "NO-CARRIER"; then sleep ${CARRIER_TIMEOUT:-2} # Some cards are plain slow to come up. Don't fail immediately. if ip link show dev "$INTERFACE" | fgrep -q "NO-CARRIER"; then report_iproute "No connection" fi fi And if I bring up the connection with the old rc.conf syntax, 'ip link show dev eth0' indeed shows: 2: eth0: <NO-CARRIER,BROADCAST,MULTICAST,UP> mtu 1500 qdisc pfifo_fast state DOWN qlen 1000 link/ether 00:30:67:8f:7c:a8 brd ff:ff:ff:ff:ff:ff Which maybe means something to someone. ;) At this point, I'm ready to chalk it up to the hardware. I can reboot my laptop, and the light on the router that indicates that it sees the ethernet cable will only turn off for a second here and there throughout the shutdown/boot process. I do the same with this machine, and don't see so much as a flicker. I tried downloading and booting from an ubuntu live cd and didn't have any luck getting a connection. And both of my machines are using the same NIC (at least according to lspci), and should be at roughly the same version of the applicable software -- I updated my laptop an hour, at most, before I updated my desktop.
